ABSTRACT:
A rotary assembly for use in processing a tubular member wherein the assembly comprises a gripping mechanism, that is moveable from an open position to a closed position. In the closed position the gripping mechanism engages at least a portion of the tubular member. The gripping mechanism is operatively engaged to a piston that is fluid actuatable from a first position to a second position by a fluid acting upon the piston, such that when the piston is in the first position the gripping mechanism is in the closed position and when the piston is in the second position the gripping mechanism is in the open position. The assembly defines a circuit through which the fluid is transmitted to the piston.
