Self-propelled vehicle with telescopic forks for handling loaded pallets in warehouses and warehouse

摘要

The trolley (6) with telescopic forks (45) services a storage area with loads (8) on pallets. It comprises a cradle (16) equipped with wheels (17,18) and a drive for one of the wheels. A chassis (23) mounted in the cradle can vertically displace the cradle relative to the chassis. The chassis has at its lower end a steering ring with bearings (47) comprising a fixed part (48) connected to the chassis and a part (49) freely rotating relative to the fixed part. The steering ring can support an axial load and a motor reduction gear and chain (50,51) rotate the trolley assembly relative to the part free to rotate on the steering ring. The storage area comprises a structure with several storage levels. Each level comprises several pairs of rails, each pair defining a corridor for circulation of the trolleys. The pallet loads are stored either side of each corridor on supports parallel to the rails.
