IN-LOADING PLATFORM STORAGE TYPE LOAD RECEIVING PLATFORM ELEVATING/LOWERING DEVICE

PROBLEM TO BE SOLVED: To provide an in-loading platform storage type load receiving platform elevating/lowering device which can be automatically secured at a working position as the load receiving platform elevating/lowering device is turned, and automatically returned to a securable condition again at the working position when the load receiving platform is arranged in a storage position. SOLUTION: In the in-loading platform storage type load receiving platform elevating/lowering device, the load receiving platform is elevated/lowered between a loading platform and the ground, and the load receiving platform elevating/lowering device is turnable between the storage position at which the load receiving platform elevating/lowering device is arranged within the loading platform around a turning post 46 erected in the loading platform, and the working position outside the loading platform. The load receiving platform elevating/lowering device has a securing means 5 which automatically stops and secures the turning operation at the working position, and a returning means 7 which releases the securing by the securing means 5 and returns the securing means 5 in a securable condition at the working position when the elevating/lowering device is arranged from the working position to the storage position.
