发明名称 Precision grapple
摘要 The precision grapple-which is removably attachable to a vehicle which has implement fittings to which civil engineering implements are removably attachable-has a forwardly converging, low walled lifting bed so that oddly shaped objects-such as rocks and boulders-can be moved, held, and carried by the grapple, has a forwardly converging tongue which is removably attachable to the lifting bed to extend the lifting bed, and has a prong with two arms spaced to clear a tall object-such as a balled tree-held on the lifting bed by the prong.
