Abstract
A paper roll-handling clamp for lift trucks of the pivoted arm type. The pivoting movement of the clamp arms with respect to one another to perform the clamping function is accomplished by use of a generally forwardly extending, selectively extensible and retractible multi-stage telescoping hydraulic piston and cylinder assembly, which gives the clamp arms an exceptionally wide range of motion.
