Abstract
A walkie low-lift truck with tiltable platen having improved stability and tilting characteristics. The truck comprises a main frame, on which are mounted a drive-steer wheel and motorized propulsion means, and a tiltable load-supporting frame connected to the front of the main frame and supported by load-carrying wheels mounted on rearwardly foldable struts. A load-carrying platen is attached to the load-supporting frame and is movable between a raised position for supporting and transporting a load and a lowered position in which the upper surface of the platen slopes forward and downward from the main frame so that the front edge thereof is in close proximity to the floor to allow a load to be picked up or discharged. The rearwardly foldable struts move the load-carrying wheels rearwardly toward the main frame to lower the platen while a mechanical linkage holds the main frame of the lift truck in a constant attitude with respect to the floor, thereby maximizing the angle of articulation which may be obtained between the main frame and platen. Conversely, as the struts are moved forwardly to unfolded, generally vertical positions to raise the platen, the load-carrying wheels are…
