发明名称 Multidirectional grapple
摘要 A multidirectional grapple for a backhoe unit is disclosed. The backhoe unit includes a boom and a forwardly extending stick pivotally mounted to the boom. A mounting base is pivotally mounted to the forward end of the stick, and the grapple assembly includes a back jaw mounted to the base through a rotatable hydraulic system. The back jaw has pivotally attached to it a hydraulically powered forward jaw with the back and forward jaws being so oriented as to open widely forwardly of the backhoe unit, and to rotate as a unit toward one side or the other so as to bite horizontally into a building or the like. The jaws have arcuate, opposing tines which interleave with one another to crush debris between them. The tines of the back jaw extend downwardly and outwardly of the mounting base in position to rake the ground of debris. The mounting base is hydraulically powered and is pivotal about a horizontal axis transverse of the stick to raise and lower the jaws as a unit.
