The field proven Tri-Grip® Backup features a three head design that encompasses the tubular that applies an evenly distributed gripping force. The Tri-Grip®Backup provides exceptional gripping capabilities with either Eckel True Grit® dies or Pyramid Fine Tooth dies. The hydraulic backup is suspended at an adjustable level below the power tong by means of three hanger legs and allowing the backup to remain stationary while the power tong moves vertically to compensate for thread travel of the connection.

Special applications and tough requirements demanded that we respond with a new tong designed and built with today"s pipe handling challenges in mind, the 8⅝ Hydra-Shift® HT. By utilizing a two-speed mechanical shift transmission in conjunction with the two speed Hydra-Shift® motor, the operator has a more flexible choice of torque/RPM"s to work with during make-up or break-out. At the beginning of the job, the operator will choose a tong gear ratio that is most appropriate for the current tubular connection and shift the variable speed motor handle into high or low as required. This tong also offers sliding heads with wrap-around dies, which provides evenly applied pressure to the pipe and a greater pipe gripping coverage, which reduces tubular damage. This tong not only offers the operator the speed options down to the slow speed parameter now demanded by the pipe manufacturers and oil companies, but it also has the option of speeds of 100 RPM"s when required. Available torque: 40,000 ft-lb

The Tri-Grip® Backup is the industry standard for reliable make-up and break-out of tubular connections that are optionally supplied with Eckel tongs. Utilizing two hydraulic cylinders and a three head arrangement ensures a slip-free operation. The backup is suspended at an adjustable level below the power tong employing three hanger legs and allowing the backup to remain stationary while the power tong moves vertically to compensate for the connection"s thread travel. The Tri-Grip® uses two pivoting heads and one stationary. The Eckel Tri-Grip® Backup has exceptional gripping capabilities with Rig Die
