Abstract
A pallet-truck-compatible load elevator includes a vertical mast and a carriage coupled to the mast for vertical motion of the carriage along the mast. The retractable forks are housed in assemblies connected to the carriage and are beyond the front face of the carriage when in retracted position, such that access to the front face of the carriage is unobstructed to a pallet truck carrying a pallet. Each fork assembly includes an outer fork coupled to a support attached to the carriage and an inner fork coupled to the outer fork, the outer fork being horizontally movable with respect to the carriage and the inner fork being similarly movable with respect to the outer fork to provide telescopic extension and retraction of the fork assemblies.
