摘要： A grip attachment to an implement arm of construction or industrial equipment via a swivel coupling comprises three interdigitating, articulate fingers, two pivotable about a first axis and the other pivotable about a second axis parallel to the first. Each finger consists of a first segment pivotable about the first or second axis and a second segment pin-jointed to the first segment. Hydraulic cylinders are employed to cause pivotal motion of the fingers about the first and second axes, and of their second segments relative to the first segments. An additional hydraulic cylinder acts to cause pivotal displacement of the second axis about the first axis, so that the finger pivotable about the second axis can be extended and contracted with respect to the other two fingers.
