Abstract
Improved bolted joint designs are used for a joint between a bolt-on load-lifting member such as a fork or clamp arm and a carriage or carrier associated with a material handling device. In various embodiments, an elongate rear vertical shank of one or the other of the load-lifting member or the carrier may have a plurality of mounting bolt holes spaced longitudinally along its length, each mounting bolt hole extending from a respective recessed area formed in one or both of the joined surfaces. Each bolt hole has a respective bolt-hole width dimension transverse to the elongate member, and each recessed area has a recess width dimension parallel to and greater than the bolt-hole width dimension.
