ABSTRACT:
A stacker crane comprising a trolley movable above the ground, a generally vertical rigid mast depending form the trolley, an assembly including a frame moveable along the mast, and a load engaging mechanism mounted on the frame, an adaptor plate mounted on the frame for vertical movement relative thereto, and a brake mechanism including a housing fixed against vertical movement relative to the plate, a brake member which is supported by the housing and which engages the mast to prevent downward movement of the housing relative to the mast consequent to undesirable downward movement of the assembly relative to the mast, and a shock absorber which is fixed relative to one of the adaptor plate and the frame, which engages the other of the adaptor plate and the frame and which stops downward movement of the frame relative to the adaptor plate over a predetermined distance.
