Description

Die vorliegende Erfindung betrifft eine Hubvorrichtung, umfassend

  • ein Fahrgestell, mit zwei Seitenteilen und wenigstens einem Querträger, wobei der Querträger die beiden Seitenteile miteinander verbindet,
  • zumindest eine Masteinheit, die einen sich in Hochrichtung der Hubvorrichtung erstreckenden Mast aufweist und
  • zumindest ein höhenverstellbares Anschlussmittel zum Anschluss eines Hebezeugs.
The present invention relates to a lifting device, comprising
  • a chassis, with two side parts and at least one cross member, the cross member connecting the two side parts together,
  • at least one mast unit, which has a mast extending in the vertical direction of the lifting device and
  • at least one height-adjustable connection means for connecting a hoist.

Hubvorrichtungen dieser Art sind in vielen Varianten aus dem Stand der Technik bekannt. Sie werden zum Heben und Senken sowie zum Transportieren von verschiedenen Gegenständen oder sogar zum Transport von Personen verwendet.Lifting devices of this type are known in many variants from the prior art. They are used for lifting and lowering as well as transporting various objects or even transporting people.

Je nach zu transportierender oder zu hebender oder zu senkender Last, werden unterschiedliche Anforderungen an Hubvorrichtungen gestellt. Ist eine Hubvorrichtung für eine schwere Last vorgesehen oder soll eine Last in eine große Höhe gehoben werden, ist zum Beispiel ein anderes Fahrgestell sinnvoll als bei leichten Lasten und geringen Hubhöhen. Außerdem ist es möglich, dass besondere Umgebungen spezielle Fahrwerke erforderlich machen, damit die Last vom Startpunkt eines Transportes abgeholt oder am Zielpunkt abgeliefert werden kann.Depending on the load to be transported or lifted or lowered, different requirements are placed on lifting devices. If a lifting device is intended for a heavy load or if a load is to be lifted to a great height, a different chassis makes sense than for light loads and low lifting heights. It is also possible that special environments require special chassis so that the load can be picked up from the starting point of a transport or delivered to the destination point.

So kommt es, dass schon heute Hubvorrichtungen mit unterschiedlich breiten Fahrgestellen und unterschiedlich langen Fahrgestellen hergestellt werden.This is why lifting devices with chassis of different widths and chassis of different lengths are already being manufactured today.

Die unterschiedlichen Fahrgestelle machen derzeit Sondermodelle notwendig, die oft durch den Umbau eines Serienmodells geschaffen werden.The different chassis currently make special models necessary, which are often created by converting a series model.

Solche Sondermodelle sind daher oft nur mit einem deutlichen Mehraufwand im Vergleich zu einem Serienmodell herstellbar. Das macht Sondermodelle dann häufig teuer. Auch kann auf die Nachfrage nach einem Hubwagen mit einem besonderen Fahrwerk nicht schnell reagiert werden.Such special models can therefore often only be produced with significant additional effort compared to a series model. This often makes special models expensive. It is also not possible to respond quickly to the demand for a pallet truck with a special chassis.

Hier setzt die vorliegende Erfindung an.This is where the present invention comes into play.

Der vorliegenden Erfindung liegt das Problem zugrunde, den unterschiedlichen Anforderungen an ein Fahrgestell eines Hubwagens zu genügen.The present invention is based on the problem of meeting the different requirements of a pallet truck chassis.

Aus dem Dokument US 2009/0020369 A1 ist es zwar bekannt, dass ein Fahrgestell umgebaut werden kann. So können Räder und Lenkrollen ausgetauscht werden. Auch die Fahrtrichtung der Hubvorrichtung kann um 90° gedreht werden. Darin beschränken sich allerdings die Variationsmöglichkeiten, die durch das Konzept des aus dem Dokument US 2009/0020369 A1 bekannten Hubwagens möglich sind. Eine Anpassung der Breite des Fahrwerks des Hubwagens ist zum Beispiel nicht möglich.From the document US 2009/0020369 A1 It is known that a chassis can be converted. This means that wheels and castors can be replaced. The direction of travel of the lifting device can also be rotated by 90°. However, the possible variations are limited by the concept of the document US 2009/0020369 A1 known pallet truck are possible. For example, it is not possible to adjust the width of the pallet truck chassis.

Das der Erfindung zu Grunde liegende Problem wird erfindungsgemäß durch eine Hubvorrichtung nach Anspruch 1 gelöst.The problem on which the invention is based is solved according to the invention by a lifting device according to claim 1.

Das Fahrgestell ist modular ausgebildet. Modular in diesem Sinne, dass das Fahrgestell aus mehreren Teilen zusammengesetzt ist. Die Teile haben Verbindungsstrukturen, über die sie miteinander verbunden sind. Ein solches modulares Fahrgestell kann je nach den Anforderungen nach Art eines Baukastens aus unterschiedlichen Teilen zusammengesetzt werden, solange gegeneinander austauschbare Teile gleiche Verbindungsstrukturen zur Verbindung mit den anderen Teilen des Fahrgestells oder des Hubwagens aufweisen. Die Teile können monolithisch sein.The chassis is modular. Modular in the sense that the chassis is made up of several parts. The parts have connecting structures through which they are connected to each other. Depending on the requirements, such a modular chassis can be assembled from different parts in the form of a modular system, as long as interchangeable parts have the same connecting structures for connection with the other parts of the chassis or the pallet truck. The parts can be monolithic.

Bei einer erfindungsgemäßen Hubvorrichtung sind die Seitenteile und der Querträger Module des Fahrgestells. So können die Seitenteile variiert werden, um speziellen Anforderungen zu genügen, ohne dass der Querträger verändert werden muss. Umgekehrt kann der Querträger variiert werden, ohne dass die Seitenteile verändert werden müssen. Lediglich die Verbindungsstrukturen müssen beibehalten werden, damit die Verbindung zwischen den Teilen hergestellt werden kann.In a lifting device according to the invention, the side parts and the cross member are modules of the chassis. This means the side panels can be varied to meet specific requirements without having to change the cross member. Conversely, the cross member can be varied without having to change the side parts. Only the connecting structures need to be retained so that the connection between the parts can be established.

Der Quertäger kann monolithisch ausgebildet sein.The cross member can be monolithic.

Nicht nur das Fahrgestell als gesamtes, auch die Seitenteile des Fahrgestells sind modular ausgebildet. Dadurch wird die Modularität des gesamten Fahrgestells erhöht.Not only the chassis as a whole, but also the side parts of the chassis are modular. This increases the modularity of the entire chassis.

Jedes Seitenteil umfasst mehrere monolithische Abschnitte, die miteinander verbunden sind und Module der modularen Seitenteile sind. Die Abschnitte jedes Seitenteils haben Verbindungsstrukturen, über die sie mit einem weiteren Abschnitt des Seitenteiles und/oder mit dem Querträger verbunden sind.Each side panel includes multiple monolithic sections that are connected to each other and are modules of the modular side panels. The sections of each side part have connecting structures via which they are connected to another section of the side part and/or to the cross member.

Jedes Seitenteil einer erfindungsgemäßen Hubvorrichtung umfasst einen ersten Abschnitt, einen zweiten Abschnitt und einen dritten Abschnitt, die miteinander verbunden sind.Each side part of a lifting device according to the invention comprises a first section, a second section and a third section, which are connected to one another.

Der Querträger ist mit einem dritten Abschnitt jedes Seitenteils verbunden.The cross member is connected to a third section of each side panel.

Die ersten Abschnitte, die zweiten Abschnitte und der Querträger sind Hohlprofile mit einem in ihrer Haupterstreckungsrichtung gleichförmigen Querschnittsprofil. Die Hohlprofile sind Rohre, insbesondere Rechteckrohre, die durch Ablängen aus einem längeren Rohr hergestellt werden können. Dadurch ist möglich ohne besondere Lagerhaltung für die Module der Seitenteile oder der Querträger, je nach Anforderung an den zu fertigenden Hubwagen, zur Herstellung der Module die benötigten Rohre abzuschneiden.The first sections, the second sections and the cross member are hollow profiles with a cross-sectional profile that is uniform in their main direction of extension. The hollow profiles are tubes, especially rectangular tubes, which can be produced by cutting a longer tube to length. This makes it possible to cut off the tubes required to produce the modules without special storage for the modules of the side parts or the cross members, depending on the requirements of the pallet truck to be manufactured.

Gemäß der Erfindung weisen die ersten Abschnitte und die zweiten Abschnitte zumindest an jeweils einem Ende und der Querträger an beiden Enden je eine Ausnehmung als Verbindungsstruktur auf.According to the invention, the first sections and the second sections each have a recess as a connecting structure at least at one end and the cross member at both ends.

Gemäß der Erfindung weisen die dritten Abschnitte hervorstehende Bereiche auf, die jeweils einen Querschnitt aufweisen, der wenigstens einem lichten Querschnitt einer als Verbindungsstruktur vorgesehenen Ausnehmung entspricht. Die hervorstehenden Bereiche können dann zur Verbindung des dritten Abschnitts mit dem ersten und/oder dem zweiten Abschnitt und/oder mit dem Querträger in deren Ausnehmungen eingesteckt werden.According to the invention, the third sections have protruding areas, each of which has a cross section which corresponds to at least one clear cross section of a recess provided as a connecting structure. The protruding areas can then be inserted into their recesses to connect the third section to the first and/or the second section and/or to the cross member.

Das bedeutet, dass der erste Abschnitt, der zweite Abschnitt und der dritte Abschnitt jedes Seitenteils durch Steckverbindungen miteinander verbunden sind. Ebenso sind die dritten Abschnitte der Seitenteile und der Querträger durch Steckverbindungen miteinander verbunden. Die Steckverbindungen können durch Stifte, Schrauben oder anderes gegen ein Lösen gesichert sein.This means that the first section, the second section and the third section of each side part are connected to one another by plug connections. The third sections of the side parts and the cross member are also connected to one another by plug connections. The plug connections can be secured against loosening by pins, screws or other means.

Der dritte Abschnitt einer erfindungsgemäßen Hubvorrichtung kann ein Gussteil sein.The third section of a lifting device according to the invention can be a casting.

Die ersten Abschnitte der Seitenteile können gleich sein. Ebenso können die zweiten Abschnitte der Seitenteile gleich sein. Dagegen können die dritten Abschnitte der Seitenteile flächensymmetrisch zueinander sein.The first sections of the side parts can be the same. Likewise, the second sections of the side parts can be the same. In contrast, the third sections of the side parts can be surface-symmetrical to one another.

An den Seitenteilen können über Rollenhalter Rollen befestigt sein. Die Rollenhalter und die Rollen können paarweise gleich sein.Rollers can be attached to the side parts via roller holders. The reel holders and the reels can be the same in pairs.

Unter Bezugnahme auf Fig. 1 bis 3 umfasst eine Hubvorrichtung H, die gemäß einem ersten Ausführungsbeispiel der vorliegenden Erfindung ausgeführt ist, ein Fahrgestell 2 sowie eine Masteinheit 1, die an dem Fahrgestell 2 angebracht ist.With reference to Fig. 1 to 3 comprises a lifting device H, which is designed according to a first exemplary embodiment of the present invention, a chassis 2 and a mast unit 1 which is attached to the chassis 2.

Das Fahrgestell 2 weist zwei sich parallel zueinander erstreckende Seitenteile 3, 4 auf, die mittels eines Querträger 5, der sich in Querrichtung zwischen diesen erstreckt, miteinander verbunden sind.The chassis 2 has two side parts 3, 4 which extend parallel to one another and which are connected to one another by means of a cross member 5 which extends in the transverse direction between them.

Bei dem Querträger 5 (siehe insbesondere Fig. 7) kann es sich um ein Rechteckrohr oder ein anderes Profilteil mit einem über seine Länge gleichförmigen Profilquerschnitt handeln.In the case of the cross member 5 (see in particular Fig. 7 ) it can be a rectangular tube or another profile part with a profile cross-section that is uniform over its length.

Jedes der beiden Seitenteile 3, 4 umfasst einen vorderen (ersten) Abschnitt 30, 40 (siehe insbesondere Fig. 4), der vorzugsweise als Profilteil mit gleichförmigem Querschnitt, insbesondere als Rechteckrohr, ausgebildet ist. Jeder der beiden vorderen Abschnitte 30, 40 der Seitenteile 3, 4 weist ein freies Ende auf, an dem über einen ersten Rollenhalter 33, 43 jeweils eine Rolle 44 angebracht ist. Diese beiden Rollen 34, 44 können relativ zu einer Hochachse der Hubvorrichtung H drehbar sein (Lenkrollen). Es könnten aber auch Bockrollen verwendet werden.Each of the two side parts 3, 4 includes a front (first) section 30, 40 (see in particular Fig. 4 ), which is preferably designed as a profile part with a uniform cross section, in particular as a rectangular tube. Each of the two front sections 30, 40 of the side parts 3, 4 has a free end to which a respective roller 44 is attached via a first roller holder 33, 43. These two rollers 34, 44 can be rotatable relative to a vertical axis of the lifting device H (swivel rollers). However, fixed castors could also be used.

Jedes der beiden Seitenteile umfasst ferner einen hinteren (zweiten) Abschnitt 31, 41 (siehe insbesondere Fig. 5), der vorzugsweise ebenfalls als Profilteil mit gleichförmigem Querschnitt, insbesondere als Rechteckrohr, ausgebildet ist. An den freien Enden der beiden hinteren Abschnitte 31, 41 der Seitenteile 3, 4 können über je einen zweiten Rollenhalter 35, 45 jeweils eine Lenkrolle 36, 46 angebracht sein. Die Lenkrollen 34, 44, 36, 46 sind um die Hochachse der Hubvorrichtung H bewegbar, so dass mit ihnen zum Beispiel Lenkbewegungen durchgeführt werden können. Die Bewegbarkeit der Rollen um die Hochachse kann durch einen Mechanismus blockiert oder zumindest eingeschränkt werden. Alternativ können dies auch Bockrollen sein.Each of the two side parts further comprises a rear (second) section 31, 41 (see in particular Fig. 5 ), which is preferably also designed as a profile part with a uniform cross section, in particular as a rectangular tube. A swivel roller 36, 46 can be attached to the free ends of the two rear sections 31, 41 of the side parts 3, 4 via a second roller holder 35, 45. The steering rollers 34, 44, 36, 46 can be moved about the vertical axis of the lifting device H, so that steering movements can be carried out with them, for example. The mobility of the rollers around the vertical axis can be blocked or at least restricted by a mechanism. Alternatively, these can also be fixed rollers.

Der vordere Abschnitt 30, 40 und der hintere Abschnitt 31, 41 eines jeden der beiden Seitenteile 3, 4 sind über einen mittleren (dritten) Abschnitt 32, 42 (siehe insbesondere Fig. 6), der vorzugsweise als Gussteil ausgebildet ist, miteinander verbunden. Bei dem Gussteil kann es sich um ein Aluminium-(Druck)-Gussteil, ein Graugussteil oder ein anderes Gussteil handeln. Alternativ könnte auch eine Schweißkonstruktion aus Metall oder eine Kunststoffkonstruktion, insbesondere eine Spritzguss-, Laminat- oder eine andere Kunststoffkonstruktion verwendet werden. Ebenso ist es möglich, dass die Abschnitte 32, 42 aus Profilteilen zusammen gesetzt sind, die fest miteinander verbunden sind.The front section 30, 40 and the rear section 31, 41 of each of the two side parts 3, 4 have a middle (third) section 32, 42 (see in particular Fig. 6 ), which is preferably designed as a cast part, connected to one another. The casting can be an aluminum (pressure) casting, a gray cast part or another casting. Alternatively, a welded construction made of metal or a plastic construction, in particular an injection molding, laminate or other one could also be used Plastic construction is used. It is also possible for the sections 32, 42 to be composed of profile parts that are firmly connected to one another.

An den mittleren Abschnitten 32, 42 der Seitenteile 3, 4 sind Strukturen 320, 420, 321, 421, 325, 425 zur Verbindung mit den vorderen Abschnitten 30, 40 und den hinteren Abschnitten 31, 41 sowie zur Verbindung mit dem Querträger 5 vorgesehen. Die Strukturen 325, 425 zur Verbindung mit dem Querträger 5 können monolithisch mit den übrigen mittleren Abschnitten 32, 42 verbunden sein. Es ist ebenso möglich, diese an den übrigen Abschnitten 32, 42 anzufügen, um bei der Montage der Fahrgestells Toleranzen ausgleichen zu können.On the middle sections 32, 42 of the side parts 3, 4, structures 320, 420, 321, 421, 325, 425 are provided for connection to the front sections 30, 40 and the rear sections 31, 41 and for connection to the cross member 5. The structures 325, 425 for connection to the cross member 5 can be monolithically connected to the remaining middle sections 32, 42. It is also possible to add these to the remaining sections 32, 42 in order to be able to compensate for tolerances when assembling the chassis.

Sind als Querträger 5, als vordere Abschnitte 30, 40 und als hintere Abschnitte 31, 41 Rohre vorgesehen, können als Verbindungsstrukturen 321, 421 an dem mittleren Abschnitt 32, 42 der Seitenteile 3, 4 Stutzen vorgesehen sein, die in die Rohre eingesteckt und dort durch Schrauben 37, 48 oder andere Befestigungselemente fixiert sind.If pipes are provided as cross members 5, as front sections 30, 40 and as rear sections 31, 41, connectors can be provided as connecting structures 321, 421 on the middle section 32, 42 of the side parts 3, 4, which are inserted into the pipes and there are fixed by screws 37, 48 or other fastening elements.

Die Abschnitte 30, 31, 40, 41 können Rechteckrohre mit gleichem Querschnittsprofil sein. Vorzugsweise werden die Abschnitte 30, 31, 40, 41 durch Abtrennen von einem Rohr hergestellt. Vorzugsweise sind die vorderen Abschnitte 30, 40 identisch und auch die hinteren Abschnitte 31, 41 identisch. Ebenso sind die Rollenhalter 33, 43 identisch und die Rollenhalter 35, 45 identisch. Das gleiche gilt für die Rollen 34, 44, die ebenso identisch sind wie die Rollen 36, 46. Lediglich die mittleren Abschnitte 32, 42 der Seitenteile 3, 4 sind nicht identisch. Dafür sind diese flächensymmetrisch zu einer Fläche senkrecht zu einer Ebene, die durch Aufstandspunkte der Rollen 34, 44, 36, 46 auf einem Untergrund aufgespannt ist.The sections 30, 31, 40, 41 can be rectangular tubes with the same cross-sectional profile. Preferably, the sections 30, 31, 40, 41 are produced by cutting off a tube. Preferably the front sections 30, 40 are identical and the rear sections 31, 41 are also identical. Likewise, the roll holders 33, 43 are identical and the roll holders 35, 45 are identical. The same applies to the rollers 34, 44, which are identical to the rollers 36, 46. Only the middle sections 32, 42 of the side parts 3, 4 are not identical. For this purpose, these are surface-symmetrical to a surface perpendicular to a plane which is spanned by contact points of the rollers 34, 44, 36, 46 on a surface.

Ein Vorteil des beschriebenen Fahrgestells 2 mit den u. a. aus den Abschnitten 30, 31, 32, 40, 41, 42 der Seitenteile 3, 4 und dem Querträger 5 aufgebauten Fahrgestell 2 ist, dass durch eine Variation der Längen des Querträgers 5 und der Abschnitte 30, 31, 32, 40, 41, 42 der Seitenteile 3, 4 ohne großen technischen Aufwand Fahrgestelle 2 mit anderen Dimensionen geschaffen werden können. Durch die Wahl eines kürzeren oder längeren Querträgers 5 kann ein schmaleres oder breiteres Fahrgestell 2 geschaffen werden. Eine Änderung der Seitenteile 3, 4 oder der Masteinheit 1 ist dazu nicht oder nicht grundsätzlich erforderlich. Durch eine Variation der Länge der Abschnitte 30, 31, 40, 41 der Seitenteile 3, 4 kann ein größerer oder kleinerer Überstand des Fahrgestelles 2 über die Masteinheit 1 nach vorne oder nach hinten erzielt werden. Die mittleren Abschnitte 32, 42 müssen dazu nicht geändert werden. Ebenso ist es möglich, anstelle der beschriebenen und in den Figuren dargestellten vorderen oder hinteren Abschnitte 30, 31, 40, 41 zumindest teilweise anders gestaltete Abschnitte für die Seitenteile 3, 4 zu wählen, wenn das zum Beispiel der Einsatzzweck des Hubwagens sinnvoll oder notwendig macht. Der vordere Abschnitt 30, 40 oder der hintere Abschnitt 31, 41 könnten beispielsweise Abkröpfungen aufweisen oder ähnliches.An advantage of the chassis 2 described with, among other things: chassis 2 constructed from the sections 30, 31, 32, 40, 41, 42 of the side parts 3, 4 and the cross member 5 is that by varying the lengths of the cross member 5 and the sections 30, 31, 32, 40, 41, 42 of the side parts 3, 4 chassis 2 with other dimensions can be created without great technical effort. By choosing a shorter or longer cross member 5, a narrower or wider chassis 2 can be created. A change to the side parts 3, 4 or the mast unit 1 is not necessary or not fundamentally necessary. By varying the length of the sections 30, 31, 40, 41 of the side parts 3, 4, a larger or smaller projection of the chassis 2 over the mast unit 1 to the front or rear can be achieved. The middle sections 32, 42 do not need to be changed for this. It is also possible to choose at least partially differently designed sections for the side parts 3, 4 instead of the front or rear sections 30, 31, 40, 41 described and shown in the figures, if, for example, the intended use of the pallet truck makes this sensible or necessary . The front section 30, 40 or the rear section 31, 41 could, for example, have offsets or something similar.

Oberhalb der beiden Rollen 36, 46 erstreckt sich in Querrichtung des Fahrgestells 2 ein Bremsbetätigungsbügel 9, mittels dessen eine auf die beiden Rollen 36, 46 wirkende Bremseinrichtung festgestellt beziehungsweise wieder gelöst werden kann. Der Bremsbetätigungsbügel 9 ist an den Rollenträgern 35, 45 für die hinteren Rollen 36, 46 schwenkbar gelagert. Die Bremse ist auf herkömmliche Art und Weise ausgestaltet.Above the two rollers 36, 46, a brake actuation bracket 9 extends in the transverse direction of the chassis 2, by means of which a braking device acting on the two rollers 36, 46 can be locked or released again. The brake actuation bracket 9 is pivotally mounted on the roller carriers 35, 45 for the rear rollers 36, 46. The brake is designed in a conventional manner.

Unter dem Querträger 5 ist ein Gehäuse 6 vorgesehen. In diesem Gehäuse 6 ist eine Antriebseinheit untergebracht, mit welcher ein nicht dargestelltes Hebezeug angehoben und abgesenkt werden kann. Die Antriebseinheit ist dazu in an sich bekannter Art und Weise über eine Spindel, die in der Masteinheit 1 angeordnet ist, mit einem Schlitten gekoppelt, der einerseits in dem Mast 10 verschiebbar angeordnet ist und andererseits mit dem Hebezeug verbunden ist.A housing 6 is provided under the cross member 5. A drive unit is housed in this housing 6, with which a Hoist, not shown, can be raised and lowered. For this purpose, the drive unit is coupled in a manner known per se via a spindle which is arranged in the mast unit 1 to a carriage which, on the one hand, is displaceably arranged in the mast 10 and, on the other hand, is connected to the hoist.

Die Masteinheit 1 umfasst einen Mast 10 und eine Mastfuß 11.The mast unit 1 comprises a mast 10 and a mast foot 11.

Der Mastfuß 11 schafft die Verbindung zwischen dem Mast 10 und dem Querträger 5. Der Mastfuß 11 umfasst dazu ein erstes Teil 110, vorzugsweise in der Form einer Platte, insbesondere eines Metallbleches, die auf der Oberseite des Querträgers 5, vorzugsweise durch Verschrauben befestigt ist. In einem Winkel dazu, der einer Neigung des Mastes 10 entspricht, ist ein zweites Teil 111 vorgesehen, das zum einen mit dem ersten Teil 110 und zum anderen mit dem Mast 10 verbunden ist. Das zweite Teil ist ebenfalls vorzugsweise eine Platte, insbesondere ein Metallblech, die an die Rückseite des Mastes 10 geschraubt ist. Die beiden Teile 110, 111 sind vorzugsweise durch Schweißen miteinander verbunden. Wenigstens ein drittes Teil (nicht dargestellt) kann als Strebe vorgesehen sein, welches zusätzlich zur Schweißverbindung zwischen dem ersten und dem zweiten Teil 110, 111 eine Verbindung schafft. Dieses dritte Teil ist vorzugsweise dazu vorgesehen Drehmomente, die auf den Mast 10 wirken, abzufangen und vom ersten Teil 110 in das zweite Teil 111 des Mastfußes 10 abzuleiten. Das dritte Teil seinerseits kann über vierte Teile (nicht dargestellt), vorzugsweise ebenfalls Streben, gegenüber dem ersten Blech 110 abgestützt sein. Die Verbindung zwischen dem dritten Teil und dem ersten und zweiten Teil 110, 111 sowie dem oder den vierten Teilen und dem dritten und dem ersten Teil 110 ist ebenfalls durch Schweißen hergestellt.The mast base 11 creates the connection between the mast 10 and the cross member 5. For this purpose, the mast base 11 comprises a first part 110, preferably in the form of a plate, in particular a metal sheet, which is fastened to the top of the cross member 5, preferably by screwing. At an angle thereto, which corresponds to an inclination of the mast 10, a second part 111 is provided, which is connected on the one hand to the first part 110 and on the other hand to the mast 10. The second part is also preferably a plate, in particular a metal sheet, which is screwed to the back of the mast 10. The two parts 110, 111 are preferably connected to one another by welding. At least a third part (not shown) can be provided as a strut, which creates a connection in addition to the welded connection between the first and second parts 110, 111. This third part is preferably intended to absorb torques that act on the mast 10 and to divert them from the first part 110 into the second part 111 of the mast base 10. The third part, in turn, can be supported relative to the first sheet 110 via fourth parts (not shown), preferably also struts. The connection between the third part and the first and second parts 110, 111 and the fourth part or parts and the third and first parts 110 is also made by welding.

Ein Vorteil der Masteinheit 1 mit dem beschriebenen oder einem funktional vergleichbaren Mastfuß 11 ist, dass die Masteinheit 1 mit diesem Mastfuß 11 an einer im Grunde beliebigen Basis befestigt werden kann. Die Basis kann im Grunde ein beliebiges Fahrgestell 2 sein und es ist nicht notwendig, dass das Fahrgestell 2 auf die vorbeschriebene Art und Weise gestaltet ist. Die Basis muss noch nicht einmal ein Fahrgestell 2 sein. Die Masteinheit 1 mit dem beschriebenen oder einem funktional vergleichbaren Mastfuß 11 kann an einer stationären Basis befestigt werden, zum Beispiel einem Sockel, einem Balken, einer Wand, einer auskragenden Platte o.a.An advantage of the mast unit 1 with the described or a functionally comparable mast base 11 is that the mast unit 1 with this mast base 11 can be attached to basically any base. The base can basically be any chassis 2 and it is not necessary that the chassis 2 is designed in the manner described above. The base doesn't even have to be a chassis 2. The mast unit 1 with the described or a functionally comparable mast base 11 can be attached to a stationary base, for example a base, a beam, a wall, a cantilevered plate or the like.

An einer Vorderseite des Mastes 10 ist ein Anschlussmittel 12 zum Anschluss des hier nicht explizit dargestellten Hebezeugs vorgesehen. Dieses Anschlussmittel 12 ist in einer Anschlussmittelführung 13, die in diesem Ausführungsbeispiel als sich in Hochrichtung des Mastes 10 erstreckende Führungskulisse ausgebildet ist, verschiebbar geführt, so dass ein Heben oder Senken des Anschlussmittels 12 zusammen mit dem daran angebrachten Hebezeug relativ zum Mast 10 möglich ist.On a front side of the mast 10, a connection means 12 is provided for connecting the hoist, not explicitly shown here. This connecting means 12 is slidably guided in a connecting means guide 13, which in this exemplary embodiment is designed as a guide link extending in the vertical direction of the mast 10, so that the connecting means 12 can be raised or lowered relative to the mast 10 together with the hoist attached to it.

Der Schlitten steht mit dem Anschlussmittel 12 zum Anschluss des Hebezeugs in Wirkverbindung und ermöglicht dadurch eine Aufbeziehungsweise Abwärtsbewegung des Anschlussmittels 12 relativ zum Mast 10.The carriage is in operative connection with the connecting means 12 for connecting the hoist and thereby enables an upward or downward movement of the connecting means 12 relative to the mast 10.

An einer Rückseite des Mastes 10 ist oberhalb des Mastfußes 11 ein Gehäuse 15 angebracht, innerhalb dessen eine Steuerungseinrichtung für den Hubmotor untergebracht ist, die an die Antriebseinheit angeschlossen ist und zur Steuerung der Funktionen des Hubmotors vorgesehen ist. Innerhalb des Gehäuses 15 ist ferner zumindest ein aufladbarer Akkumulator untergebracht, mittels dessen unter anderem die Steuerungseinrichtung für den Hubmotor sowie die Antriebseinheit gespeist werden können. Es ist auch eine leitungsgebundene Stromversorgung der Steuerungseinrichtung sowie der Antriebseinheit möglich.A housing 15 is attached to a rear side of the mast 10 above the mast base 11, within which a control device for the lifting motor is housed, which is connected to the drive unit and is provided for controlling the functions of the lifting motor. At least one rechargeable battery is also housed within the housing 15, by means of which, among other things, the control device for the lifting motor and the Drive unit can be fed. A wired power supply for the control device and the drive unit is also possible.

Oberhalb des Gehäuses 15 für die Steuerungseinrichtung des Hubmotors ist ein Handhabungsmittel 16 vorgesehen. Das Handhabungsmittel 16 weist einen Griffbügel 160 mit einem Basisabschnitt 161 auf, der sich beidseitig quer zum Mast 10 erstreckt und an einem sich in Hochrichtung des Mastes 10 erstreckenden Haltemittel 17 befestigt ist oder alternativ auch integral mit diesem ausgebildet sein kann. Das Haltemittel 17 ist in einer Führung 18 auf der Rückseite des Mastes 10 in Hochrichtung verschiebbar geführt, so dass eine Höhenverstellung des Haltemittels 17 mit dem daran angebrachten Handhabungsmittel 16 relativ zum Mast 10 möglich ist. Die Führung 18 ist in diesem Ausführungsbeispiel ebenfalls als Führungskulisse ausgebildet. Um das Haltemittel 17 mit dem daran angebrachten Handhabungsmittel 16 in der gewünschten Position zu fixieren, sind vorliegend z.B. zwei Halteschrauben 19a, 19b vorgesehen, die sich durch entsprechende Bohrungen des Haltemittels 17, die in Hochrichtung übereinander vorgesehen sind, hindurch erstrecken und innerhalb der Führung 18 festgelegt werden können. Nach dem Lösen der Halteschrauben 19a, 19b ist eine Höhenverstellung des Haltemittels 17 mit dem daran angebrachten Handhabungsmittel 16 möglich. Durch erneutes Festziehen der Halteschrauben 19a, 19b kann die Höhenposition des Handhabungsmittels 16 fixiert werden.A handling means 16 is provided above the housing 15 for the control device of the lifting motor. The handling means 16 has a handlebar 160 with a base section 161, which extends on both sides transversely to the mast 10 and is attached to a holding means 17 extending in the vertical direction of the mast 10 or, alternatively, can also be formed integrally with this. The holding means 17 is guided in a guide 18 on the back of the mast 10 so that it can be displaced in the vertical direction, so that a height adjustment of the holding means 17 with the handling means 16 attached to it relative to the mast 10 is possible. The guide 18 is also designed as a guide link in this exemplary embodiment. In order to fix the holding means 17 with the handling means 16 attached to it in the desired position, two retaining screws 19a, 19b are provided in the present case, which extend through corresponding bores in the holding means 17, which are provided one above the other in the vertical direction, and within the guide 18 can be determined. After loosening the retaining screws 19a, 19b, the height of the retaining means 17 can be adjusted with the handling means 16 attached to it. The height position of the handling means 16 can be fixed by tightening the retaining screws 19a, 19b again.

Der Griffbügel 160 weist ferner zwei Seitenabschnitte 162, 163 auf, die sich im Wesentlichen parallel zueinander und orthogonal von dem Basisabschnitt 161 weg erstrecken. Wie insbesondere in Fig. 1 zu erkennen, ist der Griffbügel 160 so angeordnet, dass die beiden Seitenabschnitte 162, 163 leicht schräg nach oben angestellt sind, um dadurch eine verbesserte Ergonomie zu erreichen. Das Handhabungsmittel 16 weist ferner zwei Griffteile 20, 21 auf, die an den freien Enden der beiden Seitenabschnitte 162, 163 befestigt sind. Alternativ können die beiden Griffteile 20, 21 auch integral mit dem Griffbügel 160 ausgebildet sein. Die beiden Griffteile 20, 21 erstrecken sich in Bezug auf die beiden Seitenabschnitte 162, 163 des Griffbügels 160 schräg nach unten und im Wesentlichen orthogonal zu diesen. Mittels der beiden Griffteile 20, 21 kann ein Benutzer die Hubvorrichtung H greifen und sie in der gewünschten Weise bewegen.The handlebar 160 further has two side sections 162, 163, which extend essentially parallel to one another and orthogonally away from the base section 161. Like in particular Fig. 1 As can be seen, the handlebar 160 is arranged in such a way that the two side sections 162, 163 are positioned slightly obliquely upwards thereby achieving improved ergonomics. The handling means 16 also has two handle parts 20, 21 which are attached to the free ends of the two side sections 162, 163. Alternatively, the two handle parts 20, 21 can also be formed integrally with the handle bar 160. The two handle parts 20, 21 extend obliquely downwards in relation to the two side sections 162, 163 of the handle bar 160 and essentially orthogonally to them. Using the two handle parts 20, 21, a user can grip the lifting device H and move it in the desired manner.

Unter Bezugnahme auf Fig. 3 wird deutlich, dass jedes der beiden Griffteile 20, 21 einen zentralen Griffabschnitt 200, 210 aufweist, mittels dessen ein Benutzer das jeweilige Griffteil 20, 21 greifen kann. An jeden Griffabschnitt 200, 210 jedes der beiden Griffteile 20, 21 schließt sich seitlich ein äußerer, vorliegend geschlossen ausgebildeter Bügelabschnitt 201, 211 an. Diese äußeren Bügelabschnitte 201, 211 sind dazu in der Lage, die Verletzungsgefahr für einen Benutzer, insbesondere die Gefahr von Handverletzungen, zu verringern, wenn die Hubvorrichtung H im Bereich zumindest eines der beiden Griffteile 20, 21 zum Beispiel eine Berührung mit einem anderen Gegenstand oder einer Person erfährt.With reference to Fig. 3 It becomes clear that each of the two handle parts 20, 21 has a central handle section 200, 210, by means of which a user can grip the respective handle part 20, 21. Each handle section 200, 210 of each of the two handle parts 20, 21 is adjoined laterally by an outer, in this case closed, bracket section 201, 211. These outer bracket sections 201, 211 are able to reduce the risk of injury to a user, in particular the risk of hand injuries, if the lifting device H comes into contact with another object in the area of at least one of the two handle parts 20, 21, for example a person experiences.

Darüber hinaus weist jedes der beiden Griffteile 20, 21 einen inneren, vorliegend ebenfalls geschlossen ausgebildeten Bügelabschnitt 202, 212 auf. Jeder der beiden inneren Bügelabschnitte 202, 212 schließt sich seitlich an den Griffabschnitt 200, 210 des jeweiligen Griffteils 20, 21 an. Zwischen jedem der inneren Bügelabschnitte 202, 212 und dem zugehörigen Griffabschnitt 200, 210 ist jeweils ein Aufnahmeraum 203, 213 ausgebildet, innerhalb dessen zum Beispiel zumindest eine Bedieneinheit, eine Anzeigeeinheit, eine kombinierte Bedien- und Anzeigeeinheit und/oder zumindest ein Ablageelement, angeordnet werden können/kann. In dem hier gezeigten Ausführungsbeispiel ist zudem an einer Außenseite des inneren Bügelabschnitts 202 des ersten Griffteils 20 eine Bedieneinheit 24 angebracht, mittels derer zum Beispiel die Hubbewegung des Anschlussmittels 12 für das Hebezeug gesteuert werden kann. Die Bedieneinheit 24 kann zum Beispiel berührungssensitiv ausgeführt sein. In einer bevorzugten Ausführungsform kann die Bedieneinheit 24 ein berührungssensitives Anzeigemittel umfassen, mittels dessen Bedieneingaben getätigt werden können und beispielsweise Informationen über ausgewählte Betriebsparameter der Hubvorrichtung H angezeigt werden können.In addition, each of the two handle parts 20, 21 has an inner bracket section 202, 212, which in the present case is also closed. Each of the two inner bracket sections 202, 212 adjoins the handle section 200, 210 of the respective handle part 20, 21 laterally. A receiving space 203, 213 is formed between each of the inner bracket sections 202, 212 and the associated handle section 200, 210, within which, for example, at least one operating unit, a display unit, a combined one Operating and display unit and/or at least one storage element can/can be arranged. In the exemplary embodiment shown here, an operating unit 24 is also attached to an outside of the inner bracket section 202 of the first handle part 20, by means of which, for example, the lifting movement of the connecting means 12 for the hoist can be controlled. The operating unit 24 can be designed to be touch-sensitive, for example. In a preferred embodiment, the operating unit 24 can comprise a touch-sensitive display means, by means of which operating inputs can be made and, for example, information about selected operating parameters of the lifting device H can be displayed.

Die Hubvorrichtung H kann ferner ein weiteres Gehäuse 22 aufweisen, innerhalb dessen eine Anzeige- und/oder Steuerungseinrichtung zur Steuerung eines Funktionselements, wie zum Beispiel einer Greifvorrichtung, des Hebezeugs und eine zugehörige Bedieneinheit 23 untergebracht sind. Ebenso können ggf. Informationen angezeigt werden. Dieses Gehäuse 22 ist an dem Basisabschnitt 161 des Griffbügels 160 des Handhabungsmittels 16 angebracht, insbesondere an diesen angehängt. Da die Bedieneinheit 23 für die Steuerung des Funktionselements des Hebezeugs innerhalb des an dem Griffbügel 160 angebrachten Gehäuses 22 untergebracht ist, kann erschwert werden, dass das Funktionselement des Hebezeugs von einem Benutzer während der Fahrt der Hubvorrichtung H betätigt werden kann. Daraus ergibt sich eine höhere Betriebssicherheit der Hubvorrichtung H. Da das Handhabungsmittel 16 mit Hilfe des Haltemittels 17 relativ zu dem Mast 10 in seiner Höhe verstellt werden kann, wird zudem in vorteilhafter Weise erreicht, dass das an dem Griffbügel 160 des Handhabungsmittels 16 angebrachte Gehäuse 22 und die darin untergebrachte Bedieneinheit 23 unter ergonomischen Gesichtspunkten stets auf eine optimale, an die Körpergröße eines Nutzers der Hubvorrichtung H angepasste Höhe eingestellt werden kann.The lifting device H can also have a further housing 22, within which a display and/or control device for controlling a functional element, such as a gripping device, of the hoist and an associated operating unit 23 are accommodated. Information can also be displayed if necessary. This housing 22 is attached to the base section 161 of the handlebar 160 of the handling means 16, in particular attached to it. Since the operating unit 23 for controlling the functional element of the hoist is accommodated within the housing 22 attached to the handlebar 160, it can be made difficult for the functional element of the hoist to be operated by a user while the lifting device H is moving. This results in greater operational reliability of the lifting device H. Since the height of the handling means 16 can be adjusted relative to the mast 10 with the aid of the holding means 17, it is also advantageously achieved that the housing 22 attached to the handlebar 160 of the handling means 16 and the control unit 23 housed therein is ergonomic Viewpoints can always be adjusted to an optimal height adapted to the height of a user of the lifting device H.

Unter Bezugnahme auf Fig. 9 bis 11 soll nachfolgend eine Hubvorrichtung H näher erläutert werden, die gemäß einem zweiten Ausführungsbeispiel der vorliegenden Erfindung ausgeführt ist. Der grundlegende Aufbau dieser Hubvorrichtung H unterscheidet sich vom ersten Ausführungsbeispiel in erster Linie dadurch, dass die Hubvorrichtung H drei nebeneinander angeordnete Masteinheiten 1a, 1b, 1c mit jeweils einem Mast 10a, 10b, 10c aufweist. Aus diesem Grund wurden in Fig. 9 bis 11 funktional identische Bauteilkomponenten der Hubvorrichtung H gemäß dem zweiten Ausführungsbeispiel mit denselben Bezugszeichen versehen, die bei der Beschreibung des ersten Ausführungsbeispiels verwendet wurden. Nachfolgend sollen in erster Linie nur die konstruktiven Änderungen gegenüber dem ersten Ausführungsbeispiel näher erläutert werden.With reference to Fig. 9 to 11 A lifting device H will be explained in more detail below, which is designed according to a second exemplary embodiment of the present invention. The basic structure of this lifting device H differs from the first exemplary embodiment primarily in that the lifting device H has three mast units 1a, 1b, 1c arranged next to one another, each with a mast 10a, 10b, 10c. For this reason, Fig. 9 to 11 Functionally identical components of the lifting device H according to the second exemplary embodiment are provided with the same reference numbers that were used in the description of the first exemplary embodiment. Below, only the design changes compared to the first exemplary embodiment will be explained in more detail.

Eine erste (mittlere) Masteinheit 1a der Hubvorrichtung H weist einen Mast 10a auf, der an einer diesem zugeordneten Mastfuß 11a angebracht ist, die ihrerseits an dem Querträger 5, der sich in Querrichtung zwischen den beiden Seitenteilen 3, 4 erstreckt, angebracht ist. An einer Rückseite des Mastes 10a der ersten Masteinheit 1a ist wiederum das Gehäuse 15 angebracht, innerhalb dessen die Steuerungseinrichtung zur Steuerung des Hubmotors der Hubvorrichtung H sowie ggf. der Akkumulator untergebracht sind.A first (middle) mast unit 1a of the lifting device H has a mast 10a, which is attached to a mast base 11a assigned to it, which in turn is attached to the cross member 5, which extends in the transverse direction between the two side parts 3, 4. Attached to a rear side of the mast 10a of the first mast unit 1a is the housing 15, within which the control device for controlling the lifting motor of the lifting device H and, if applicable, the accumulator are accommodated.

Das Handhabungsmittel 16 mit dem Griffbügel 160 ist wiederum oberhalb des Gehäuses 15 für die Steuerungseinrichtung des Hubmotors angeordnet und an dem sich in Hochrichtung des Mastes 10a erstreckenden Haltemittel 17 befestigt oder integral mit diesem ausgebildet. Das Haltemittel 17 ist in zwei Führungen 18a, 18b, die sich in Hochrichtung parallel zueinander erstrecken und vorliegend als Führungskulissen ausgebildet sind, auf der Rückseite des Mastes 10a der ersten Masteinheit 1a in Hochrichtung verschiebbar geführt. Dadurch wird eine Höhenverstellung des Haltemittels 17 mit dem daran angebrachten Handhabungsmittel 16 relativ zum Mast 10a der ersten Masteinheit 1a ermöglicht. Um das Haltemittel 17 mit dem daran angebrachten Handhabungsmittel 16 in der gewünschten Position zu fixieren, sind z.B. vorliegend zwei nebeneinander angeordnete Halteschrauben 19a, 19b vorgesehen, die sich durch entsprechende Bohrungen des Haltemittels 17 hindurch erstrecken und jeweils innerhalb einer der beiden Führungen 18a, 18b festgelegt werden können. Nach dem Lösen der Halteschrauben 19a, 19b ist eine Höhenverstellung des Haltemittels 17 mit dem daran angebrachten Handhabungsmittel 16 möglich.The handling means 16 with the handlebar 160 is in turn arranged above the housing 15 for the control device of the lifting motor and is attached to the holding means 17 extending in the vertical direction of the mast 10a or is formed integrally with it. The holding means 17 is in two guides 18a, 18b extend parallel to each other in the vertical direction and are designed in the present case as guide links, guided on the back of the mast 10a of the first mast unit 1a so that they can be moved in the vertical direction. This makes it possible to adjust the height of the holding means 17 with the handling means 16 attached thereto relative to the mast 10a of the first mast unit 1a. In order to fix the holding means 17 with the handling means 16 attached to it in the desired position, for example in the present case two holding screws 19a, 19b arranged next to one another are provided, which extend through corresponding bores in the holding means 17 and are each fixed within one of the two guides 18a, 18b can be. After loosening the retaining screws 19a, 19b, the height of the retaining means 17 can be adjusted with the handling means 16 attached to it.

Die Hubvorrichtung H weist ferner eine zweite Masteinheit 1b mit einem Mast 10b, der an einer diesem zugeordneten Mastfuß 11b angebracht ist, sowie eine dritte Masteinheit 1c mit einem Mast 10c, der an einer diesem zugeordneten Mastfuß 11c angebracht ist, auf. Der Mastfuß 11b der zweiten Masteinheit 1b sowie der Mastfuß 11c der dritten Masteinheit 1c sind ebenfalls an dem Querträger 5 des Fahrgestells 2 befestigt.The lifting device H also has a second mast unit 1b with a mast 10b, which is attached to a mast base 11b assigned to it, and a third mast unit 1c with a mast 10c, which is attached to a mast base 11c assigned to it. The mast base 11b of the second mast unit 1b and the mast base 11c of the third mast unit 1c are also attached to the cross member 5 of the chassis 2.

An einer Vorderseite der Masten 10b, 10c der zweiten und dritten Masteinheit 1b, 1c ist jeweils ein Anschlussmittel 12b, 12c zum Anschluss eines hier nicht explizit dargestellten Hebezeugs vorgesehen. Diese Anschlussmittel 12b, 12c sind jeweils in einer vorliegend als Führungsschlitz ausgebildeten Anschlussmittelführung 13b, 13c in Hochrichtung der Masten 10b, 10c verschiebbar geführt, so dass ein Heben und Senken der Anschlussmittel 12b, 12c zusammen mit dem daran angebrachten Hebezeug relativ zu den jeweiligen Masten 10b, 10c möglich ist.On a front of the masts 10b, 10c of the second and third mast units 1b, 1c, a connection means 12b, 12c is provided for connecting a hoist, not explicitly shown here. These connecting means 12b, 12c are each guided displaceably in the vertical direction of the masts 10b, 10c in a connecting means guide 13b, 13c, which is designed as a guide slot, so that the connecting means 12b, 12c can be raised and lowered together with the hoist attached thereto relative to the respective masts 10b , 10c is possible.

Das Gehäuse 22, innerhalb dessen die Steuerungseinrichtung zur Steuerung zumindest eines Funktionselements, wie zum Beispiel einer Greifvorrichtung, des Hebezeugs und eine zugehörige Bedieneinheit 23 untergebracht sind, ist an dem Basisabschnitt 161 des Griffbügels 160 des Handhabungsmittels 16 angebracht, insbesondere an diesen angehängt. Daraus ergeben sich die oben bereits erläuterten Vorteile.The housing 22, within which the control device for controlling at least one functional element, such as a gripping device, the hoist and an associated operating unit 23 are accommodated, is attached to the base section 161 of the handlebar 160 of the handling means 16, in particular attached to it. This results in the advantages already explained above.

An dem Griffbügel 160 sind wiederum zwei Griffteile 20, 21 angebracht, die in der oben beschriebenen Weise ausgeführt sind.Two handle parts 20, 21 are attached to the handlebar 160 and are designed in the manner described above.
