Definitions

  • 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.
  • lifting devices 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.
  • the different chassis currently make special models necessary, which are often created by converting a series model.
  • the present invention is based on the problem of meeting the different requirements of a pallet truck chassis.
  • 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.
  • 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.
  • the side parts and the cross member are modules of the chassis.
  • the side panels can be varied to meet specific requirements without having to change the cross member.
  • 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.
  • the cross member can be monolithic.
  • chassis As a whole, but also the side parts of the chassis are modular. This increases the modularity of the entire chassis.
  • 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.
  • Each side part of a lifting device comprises a first section, a second section and a third section, which are connected to one another.
  • the cross member is connected to a third section of each side panel.
  • 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.
  • 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.
  • 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.
  • 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.
  • the third section of a lifting device according to the invention can be a casting.
  • the first sections of the side parts can be the same.
  • the second sections of the side parts can be the same.
  • the third sections of the side parts can be surface-symmetrical to one another.
  • Rollers can be attached to the side parts via roller holders.
  • the reel holders and the reels can be the same in pairs.
  • 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.
  • 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.
  • cross member 5 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.
  • 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).
  • fixed castors could also be used.
  • 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.

  • the casting can be an aluminum (pressure) casting, a gray cast part or another casting.
  • 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.
  • the sections 32, 42 can be composed of profile parts that are firmly connected to one another.
  • 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.
  • 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.
  • the sections 30, 31, 40, 41 can be rectangular tubes with the same cross-sectional profile.

  • 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.
  • 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.
