The guide rails 15 face each other. The inner surface is open. The fall prevention body 11 has a window frame shape, and a pair of left and right side frame members 16 and a pair of upper and lower fall prevention members 18 connected between upper ends and lower ends of the side frame members 16 via bolts and nuts 17. Consists of. These fall prevention members 18 are formed of a rectangular cylinder, and the arrangement pitch (spacing) in the vertical direction is equal to or substantially equal to the pitch of the load receiving portion 7. Brackets 19 are provided on the rear side of the left and right ends of the fall prevention member 18.
A guide roller 21 which can be fitted into the guide rail 15 is provided at the outer end of the pin 20 in the left-right direction supported by 19 so as to be freely rotatable. In addition, at the upper and lower ends of the guide rail 15, bolts
Stoppers 22A and 22B that are detachable by a nut type are provided. The lifting device 23 interlocking with the fall prevention body 11,
A horizontal shaft rotatably provided via a bearing 26 between a bracket 25, which is attached near the upper end of the front support column 2 via a bolt / nut 24, and extends forward, and between the free ends of the bracket 25 facing left and right. 27, a pulley body 28 attached to both ends of the horizontal shaft 27, and a chain 29 hung from the pulley body 28 from above. One end of the chain 29 is connected to the upper end of the side frame member 16. At the same time, the other end can be engaged and disengaged with the locking member 32 attached to the lower front surface of the front support column 2 through the bolts and nuts 31. That is, the locking member 32 has a slit-shaped locking groove 33 opened on the front surface and the upper and lower surfaces, and by inserting one link into the locking groove 33,
The next link, which is connected to the lower portion of this link by being displaced by 180 degrees, engages with the lower surface of the locking member 32. Reference numeral 35 denotes a drum, which is an example of an object to be stored, and four pallets can be placed on one pallet 36. The stored items may be stored directly without using the pallet 36, or the stored items may be placed on the pallet 36 one by one.
