4½ Hydra-Shift® Tong
The 4½ Hydra-Shift is packed with all the features you've come to expect from Eckel: patented cam biting system, quick-change sliding heads, self-aligning open throat. Options include both torque gauge and manual backup or cam-type hydraulic backup. The unit is also available with front or side controls, standard chain bridle suspension, or with its own built-in suspension arm.
The Tri-Grip® Backup are 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 insures a slip-free operation. The 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. The Tri-Grip® uses two pivoting heads and one stationary. The Eckel Tri-Grip Backup has exceptional gripping capabilities with Rig Dies when running drill pipe or optional Eckel Wrap-Around True-Grit® dies or Pyramid Fine Tooth dies for making up other types of tubulars.
