A lifting platform provided with a pair of rails forming a letter shape, and arranged at a position in the extending direction of the rails outside the lifting space in which the lifting platform moves up and down, and at intervals equal to the vertical spacing of the upper lifting platform and the lower lifting platform. A bicycle storage space provided with multiple levels above and below, and rails for the lifting platform provided on both sides of the lower part of the bicycle storage space, having the same spacing and the same cross-sectional shape as the rails of the lifting platform, and stopping at the same height level. a pair of rails arranged in an extended manner relative to each other; a bicycle storage pallet placed above between the pair of rails in each of the bicycle storage spaces; and an upper and lower elevating platform of the elevating platform. It is placed on each platform and is supported between the grooves of the rails provided on the upper and lower lifting platforms, and the rails of both are placed between the bicycle storage spaces at the same height level as the upper and lower lifting tables. a self-propelled pallet carrier that can move freely along the pallet carrier; and a plurality of pallet lifting machines installed on the pallet carrier so that they can be vertically extended and retracted to lift the bicycle-mounted pallet and float it off the rail. , the lifting platform is located at a lower part of the lifting space where the lifting platform moves up and down, and is located outside in the extending direction of the rail of the lifting platform, and is adjusted in height to the upper and lower lifting platforms of the lifting platform that stops at the lowered position of the lifting space; It has a structure that consists of a table lifter that can be used.

[Effect]

Bicycle mounting pallets are arranged in all but one of the storage spaces, and a plurality of bicycles are mounted and stored on each pallet.

To take out a bicycle, stop the upper lifting platform at the same height as the storage space from which you want to remove the bicycle, move the carrier from the upper lifting platform into the storage space, and when the carrier lifts the pallet, it will move to the upper level. Returning to the lifting platform, the upper lifting platform descends to the lower take-out zone of the lifting space, and the bicycles on the pallet are artificially removed to the outside.

Empty pallets are transported by a lower elevating table and sent sequentially by a conveyance truck into the storage spaces emptied by the previous removal, so that the bicycles in each storage space can be taken out in order.

Furthermore, bicycles can be stored by moving an empty pallet to the take-out zone on the upper lifting platform, and when the bicycle is placed on the pallet, the pallet is sent to the previous empty storage space.
