In the case of the conventional shelving crane described above, the tension of the tension spring for tensioning the chain is such a small tension that does not cause slack in the chain for lifting the platform under the platform. Raise the lifting platform to a position near the upper limit to lengthen the loading platform lifting chain below the loading platform, and reduce the distance between the loading platform lifting chain and the props of the traveling frame. When the traveling is stopped, the carrier lifting / lowering chain below the lifting / lowering carrier may be flexed due to inertia and collide with the pillars of the traveling frame to generate noise. Also, since the end of the lifting / lowering platform on the lower side of the lifting platform is connected to the lifting platform via a tension spring for tensioning the chain, when the tension spring is disconnected, the lower platform for lifting the platform is lifted. The chain 8 falls, which is dangerous. Further, in the case of the conventional shelving crane, there is a drawback that the tension of the chain for lifting the platform cannot be adjusted.

According to the present invention, the loading platform lifting chain 8 below the lifting loading platform 1 is farther from the columns 25 and 26 of the traveling frame 9 than the loading platform lifting chain 8 above the lifting loading platform 1. Since it is arranged, even if the shelving crane 14 that is traveling with the lift platform 1 placed in the raised position is stopped,
It is possible to prevent the load carrier lifting chain 8 below the lift carrier 1 from laterally swaying due to inertia and colliding with the columns 25 and 26, and generating noise due to the collision, and the chain tension compression spring 7 Even if the chain breaks, the chain tension adjusting nut 17 is supported by the supporting member 3, so that it is possible to prevent the load platform lifting chain 8 below the lift platform 1 from dropping. By rotating the chain tension adjusting nut 17, it is possible to easily adjust the tension of the chain 8 for lifting the platform. Further, a chain tension sprocket 5 is rotatably attached to a lower portion of the support member 4 by a horizontal shaft 6 perpendicular to the traveling direction of the crane, and a chain 8 for lifting and lowering a cargo bed, one end of which is connected to the side frame member 2, The chain sprocket 5 is wound around the upper half of the sprocket 5 and hung down from the side of the sprocket 5 opposite to the side frame member 2, so that the vertical movement amount of the support member 4 at the time of adjusting the chain tension can be increased or decreased. Since the amount of movement of the lower loading platform lifting chain 8 can be halved, the chain tension compression spring 7 can be downsized.
