SEVERE DUTY GRAPPLE WITH TUBULAR PIVOT

摘要

An improved severe duty grapple (80) for attachment onto the end of a dipper stick (12) of a backhoe has an arcuate - shaped upper jaw (82) with an inner end (86) and a backside. The upper jaw is pivotally attached near its inner end on its backside to the end of a dipper stick and a double action actuator or cylinder (14) for operative pivotal movement of the upper jaw relative to the dipper stick. An arcuate - shaped lower jaw (100) is provided with an inner end and a backside. The lower jaw is attached near its inner end on its backside to the dipper stick by a linkage (16) for operative pivotal movement of the upper jaw relative to the lower jaw. A hollow tubular pivot (88) is attached to the inner end of one of the jaws with open opposing ends. Two lug plates (107,107) are mounted on the inner end of the other jaw each with an eyelet (108). The eyelets are alignable with the open ends of the hollow tubular pivot. A pivot pin (110) is passed through the hollow tubular pivot and eyelets and secured thereat.
