Abstract
A clamp lift truck for lifting a rectangular hexahedral stack of boxes incorporating a vertically movable four-side clamp lift employing a plurality of uniformly dimensioned generally flat clamp plates having widths substantially covering the surroundings of the rectangular hexahedral stack of boxes. The flat clamp plates are supported to be adapted for closely abutting against two pairs of opposing sides of the stack of boxes so as to clamp the stack with entirely uniform clamping force. A drive mechanism is utilized for driving the clamp lift into an open position for receiving the stack therebetween and a closed clmap position for simultaneously clamping two pairs of sides of the stack.
