Abstract
A lift truck-mounted load clamp for handling paper rolls having selectively openable and closeable opposing clamp arms with elongate, arcuate, concave contact pads hingedly connected to the forward ends of the respective clamp arms. Each contact pad is provided with exceptionally compact, durable restraints which limit the hinged movement of the respective pad, such restraints each comprising a cable having a swaged-on eye at one end pivotally connected to the contact pad and a swaged-on ferrule at the other end which is slidably contained within a yoke mounted on the clamp arm. A pair of such restraints are provided for each respective contact pad, the restraints being located exterior of each longitudinal edge of the clamp arm rather than interior thereof. A specially formed, heat-treated protective casting is provided on the rear surface of each contact pad which prevents wear and resultant weakening of the hinge joint of each pad, while also preventing wear and weakening of the tips of the pad, and provides an exceptionally durable and strong connection between the respective restraints and the pad.
