Abstract: A tong positioning apparatus including: (a) a base having a powered cylinder; (b) a first articulating arm attached at a first end to the cylinder and pivotally attached to the base; (c) a second arm attached at a first end to a second end of the first articulating arm; (d) a tong attached to a second end of the second arm, so that when the cylinder moves from retracted and expanded positions, the first and second arms articulate to move the tong between engaged and disengaged positions relative to conjoined tubular members; and (e) a bow structure forming an interface between the tong and the second arm that enables rotation about a generally vertical axis and with respect to an underlying support surface.

Abstract: An improved tong positioning apparatus which includes a base positionable on the rig floor; a hydraulic cylinder positioned on the base, having a first end engageable to a rear support member and a second end engageable to a pivotal moment arm; a forward shock attachment arm engaged at a first end to one of a plurality of attachment points on the moment arm, and a second end which attaches to a tong frame attachment point on the tong. The forward shock attachment arm includes a pair of shock absorbers engaged along its length to provide a smooth, non-jerking motion both vertically and horizontally in moving the power tong. The tong positioning apparatus is designed to be remotely operated by hydraulic, air, air over hydraulics, electronically, by a single operator.

Abstract: An improved tong positioning apparatus which includes a base positionable on the rig floor; a hydraulic cylinder positioned on the base, having a first end engageable to a rear support member and a second end engageable to a pivotal moment arm; a forward shock attachment arm engaged at a first end to one of three attachment points on the moment arm, and a second end which attaches to a tong frame attachment point on the tong. The forward shock attachment arm includes a pair of shock absorbers engaged along its length to provide a smooth, non-jerking motion both vertically and horizontally in moving the power tong.
