Abstract:
A gripping device for gripping and spinning a pipe body of various diameters includes a gripping assembly having a pair of gripping arms for gripping the outer surface of the pipe body, and a spinning device having a pair of rollers for spinning the pipe body as it is engaged by gripping arms. The gripping device also includes a rotatable input shaft and a coupler. The coupler connects the rotatable input shaft to the gripping assembly and to the spinning device and is employed to selectively engage the gripping arms and the spinning device. A brake is provided so as to selectively prevent at least one of the gripping assembly and the spinning device from being operated upon rotating the rotatable input shaft.
