  • Patent number: 4217074
    Abstract: The lifting mast (20), frame (12), and outriggers (16) of a slip sheet lift truck (10) are fixed and immovable with respect to one another. The platen (30), push-pull mechanism (45), and back plate (31) are an integral unit mounted to permit side shifting on a tilt carriage (29), which is mounted on lower pivots (28) and tiltable thereabout with upper tilt cylinders (35). These are carried on a lifting carriage (25) which is vertically moveable and supported by a lifting cylinder (26) on the lifting mast (20). The lift truck outriggers (16) extend and slope forwardly and downwardly from the mast (20) to provide better truck stability, clearance for the platen (30), and good underclearance for ramps and dockboards.
