  The corridor board 5 is formed of a plate-like metal member such as a steel plate, for example, and is juxtaposed in the width direction with the elevating frame 2 and used as a step when getting on and off. The corridor board 5 is provided above the upper end of the inner wall P1 by covering the transmission member 32 provided near the upper part of the inner wall P1 of the pit P.

  The corridor board support means 6 includes a corridor board support 61 that extends upward from the bottom surface P2 of the pit P, a front support member 62 that fixes the corridor board 5 to the inner wall P1 of the pit P on the front side, and a corridor on the back side. A back bracket set 63 as a back support member for fixing the plate 5 to the inner wall P1.

  Further, the walkway board column 61 avoids the transmission member 32 and the beam 41, and the front support member 62 and the back bracket set 63 are fixed to the pit P to support the walkway board 5, that is, the lifting means 3 And the walkway board support means 6 is provided in the lifting / lowering means 3 and the frame body 4 so as not to transmit vibration.

  The motor 31 is supported on the upper part of the motor support 42 at the rear of the housing frame 4 via the motor support component 8. The base 31a of the motor 31 is placed on a metal base plate 80, and bolts 81 are inserted into mounting holes opened at the four corners of the base 31a and the base plate 80. The bolts 81 are inserted above the mounting holes of the base 31a. The base 31 a and the base plate 80 are fastened by the attached nut 82 and the nut 83 attached to the bolt 81 below the attachment hole of the base plate 80. A spring washer is inserted between the base 31 a and the nut 82, and a flat washer is inserted between the base plate 80 and the nut 83. The bolt 81 is further inserted through the vibration damping mat receiver 85, the vibration damping mat 86, the motor support member 84, the vibration damping mat 87, and the large square washer 88 in order from the bottom, and is fastened with a nut 89.

  The damping mat receiver 85 is a metal plate such as SS-400 having dimensions of 12 mm × 65 mm × 230 mm, for example. The damping mats 86 and 87 are rubber mats such as a flick mat, for example. The damping mat 86 has a size of 18 mm × 60 mm × 220 mm, for example, and the damping mat 87 has a size of 7 mm × 52 mm × 52 mm, for example. The damping mat 86 is a harder mat than the damping mat 87. The motor support member 84 is sandwiched between two types of vibration damping mats 86 and 87 having different vibration absorption characteristics, and one end is fixed and supported on the motor support 42 by welding or the like. The lower surface of the motor support member 84 is also supported by reinforcing members 84a and 84b having one end fixed to the motor support 42 by welding or the like. The base plate 80, the bolt 81, the nuts 82 and 83, the motor support member 84, the reinforcing members 84a and 84b, the vibration suppression mat receiver 85, the vibration suppression mat 86, the vibration suppression mat 87, the large square washer 88, and the nut 89 are described in the claims. This corresponds to the motor support component 8.

  When the heavy lifting frame 2 moves up and down by the operation of the motor 31, a force acts to pull the motor 31 upward from the motor support member 84 due to the vertical positional relationship between the front-side main sprocket 33 and the driven sprocket 25. In this way, when a force for pulling the motor 31 upward from the motor support member 84 is actuated by the operation of the motor 31, the damping mat receiver 85 causes the damping mat 86 to be moved via the bolt 81 and the nut 89. The motor support member 84 is pressed and compressed. Thereby, the vibration generated by the operation of the motor 31 is reduced from being transmitted to the motor support member 84 by the vibration damping action of the vibration damping mat 86.

  The soundproof cover 9 covers the motor 31 by using a hard plate, for example, a metal plate, particularly a substrate made of a steel plate, having a thickness of several millimeters, in this embodiment about 3 mm, for example, a height of less than 40 cm and a width of more than 30 cm. This is due to a hollow box with a depth of less than 60 cm. In the soundproof cover 9, an opening 9a for inserting a rotating shaft for sprocket connection so as to protrude to the side surface, a slit 9b for inserting reinforcing members 84a and 84b, and a motor support member 84 are inserted. Slit 9c. The opening 9 a and the slits 9 b and 9 c expose the rotating shaft of the motor 31 to the outside of the soundproof cover 9 without contacting the soundproof cover 9 and project the motor support member 84 and the reinforcing members 84 a and 84 b from the soundproof cover 9. It is for making it happen. A lead sheet with adhesive (not shown) having a thickness of 0.5 mm is pasted on the entire inner surface of the substrate of the soundproof cover 9, and glass wool (not shown) as a sound-absorbing and soundproofing material having a thickness of 25 mm is placed on the spindle pin ( (Not shown). A door-stop sponge (not shown) is attached to the surface of the substrate facing the inner wall of the pit P of the soundproof cover 9.

  The bottom surface of the soundproof cover 9 is supported by one fixing plate portion of a supporting member 91 having a U-shaped cross section, and the other fixing plate portion of the supporting member 91 is fastened and fixed to a triangular bracket 92 by a bolt 93. The bracket 92 is fixed to the inner wall of the pit P with an anchor 94. The support member 91, the bracket 92, the bolt 93, and the anchor 94 correspond to the soundproof cover supporting component 90 in the claims.

  With the above configuration, the soundproof cover 9 is supported by the inner wall of the pit P via the soundproof cover support component 90 without contacting the motor 31 and the motor support component 8. The vibration noise is suppressed as much as possible.

  In addition, this invention is not limited to the said embodiment, Including other structures etc. which can achieve the objective of this invention, the deformation | transformation etc. which are shown below are also contained in this invention.

  For example, in the above-described embodiment, the elevating frame 3 is composed of the first frame 31 and the second frame 32 each capable of accommodating three vehicles, but the elevating frame has a pit area and depth. Accordingly, it is only necessary that an appropriate number of vehicles can be accommodated in the width direction and the vertical direction.
