ABSTRACT:
A load carrying apparatus designed to be very low relative to its length, to be capable of crawling under a string of loaded pallets in a crawl mode, to be capable of carrying the string of loaded pallets in a walk mode, and to be capable of moving a string of loaded pallets forward or backward relative to the apparatus. The apparatus includes (a) a track member, which during use of the apparatus, is moved across and in contact with a surface; (b) a load moving member carried by the track member; (c) a vertical drive mechanism for moving the load moving member vertically relative to the track member from a down position in which the load moving member is supported by the surface to a partly up position, from the partly up position to a fully up position in which, during use of the apparatus, the load moving member supports a load to be moved by the apparatus, from the fully up position to the partly up position, and from the partly up position to the down position; and (d) a horizontal drive mechanism for effecting relative horizontal movement of the track member and the load moving member when the load moving member is in either its partly up position or its fully up position.
