Lift truck load clamp having nonresilient contact pad surfaces textured for directionally variable resistance to slippage

摘要

A load-handling clamp for lift trucks having load-engaging, nonresilient contact pad surfaces specially textured for resisting slippage of the load variably depending on direction of slip. Each load-engaging surface of the contact pads is constructed of a nonresilient material, preferably metal, in which is formed a series of spaced parallel grooves, each having beveled longitudinal edges and lands therebetween, extending generally parallel to the direction of travel of the lift truck. The provision of the grooves and their orientation with respect to the lift truck provide a load-engaging surface having minimal resistance to slippage between pad and load in the direction of travel of the lift truck during engagement of the load by the clamp, but much greater resistance to slippage perpendicular to the grooves for holding the load. In addition, the surface is exceptionally resistant to wear and to clogging with bits of paper or cardboard from the loads handled.
