GRAPPLE/TONG TYPE GRIPPER

摘要

Gripper system (20) includes complementarily shaped major jaw assemblies (102) and (104) positioned face-to-face to each other to cooperatively define an arcuate jaw capable of gripping relatively larger- sized work products (192). A minor jaw assembly (160) is pivotally mounted on at least one of the major jaw assemblies. The minor jaw assembly includes a gripping section (180) complementary to the gripping section (146) of the corresponding major jaw assembly. The minor jaw assembly is movable relative to its corresponding major jaw assembly, thereby to grip relatively small-sized work pieces (190) between the minor jaw assembly and major jaw assembly.
