FIGS. 4 and 5 depict suitable heads within the power tong, and it should be understood that the size of the depicted heads is merely illustrative, and that the depicted heads may be replaced with other heads for a different sized pipe. FIGS. 4 and 5 further depict a substantially rectangular-shaped form of the body, which is one of the features of the present invention. As depicted in these FIGURES, the tong motor is substantially offset with respect to the central axis of the tong, which passes through the centerline of the cage plate and the center of the door opening.
