Current rod tongs have not been designed to stop at the shoulder, recognize the shoulder, or move to any predetermined position beyond the shoulder. They were mechanically engineered to deliver speed and an approximate torque. The Automated Rig Technologies CD Rod Tong, however, has been designed not to spin past the shoulder; once the shoulder has been reached, the tong seamlessly transitions to move a predefined distance (circumferential displacement) that is operator-adjustable. This tong will make up single or double connections and is fully mechanical, meaning there are no electronics on the tong. This leads to quicker and easier field maintenance and repairs. Optional electronic monitoring and data acquisition can be installed but are not critical to the operation of the tong. The CD tong replaces existing floor sucker-rod tongs and works with any service- or workover-rig hydraulic system.
