ABSTRACT:
A self-contained power-operated manipulator for piping and the like is capable of coordinated movements which approximate those of the human arm and hand. Spaced pairs of cooperative opposing fixed and movable jaws on a common carrier structure can rotate in two directions around the axis of a main support to which the carrier structure is pivoted on crossing relationship. The carrier structure, with the attached pairs of jaws, can be swung in two directions through large angles around the pivot axis of the carrier structure. The pairs of jaws on the carrier structure can be rotated in unison around the axis of the carrier structure and the movable jaws of the opposing pairs can be rotated relative to the fixed jaws around the axis of the carrier structure. Separate power units are utilized for producing the several movements of the manipulator in a coordinated manner. The pipe manipulator can be attached to a crane boom jib or other support.
