Patent ID: 8282111

Claim:
A cart, comprising: a frame; a plurality of wheels carried by the frame; a pallet support platform movably carried by the frame; a lift actuator carried at least in part by the frame and operably associated with the platform to move the platform up and down relative to the frame; said platform including one or more pallet retention features adapted to be engaged by a pallet disposed on the platform to limit relative sliding movement of the pallet; a guide assembly including guide members carried by the frame and guided members carried by the platform for movement relative to the guide members, the guided members being rotatably movable relative to the guide members to reduce the tendency for the guided members to bind against the guide members during movement of the platform relative to the frame; a linkage interconnecting the frame and the platform to distribute the force provided on the platform by the lift actuator to at least two spaced apart locations on the platform; and the linkage further includes first and second link sets with each link set having upper links connected to the platform and lower links connected to the frame, the upper links and lower links being connected together at a pivot, and the linkage also includes a center link interconnecting the first and second link sets.
