Product Description

7⅝ HDS-35 Tong

When application demand a wide range of sizes, this tong handles pipe sizes 2⅜ inches all the way to 7⅝. The 7⅝ HDS-35 uses a two-speed mechanical shift transmission in conjunction with the two-speed Hydra-Shift® motor, providing the operator a very flexible choice of working torque/RPMs during makeup or breakout. Our patent-pending CASE STIFFENER technology enhances overall torque to provide consistent torque output. Having a high full 360° rotational torque and speed-shifting capability ensures the tong can makeup special torque-turn connections that require continuous rotation. Also, the CASE STIFFENER technology reduces stress and wear on the rotary gear teeth.

7⅝ HDS CHROMEBOSS®: The 7⅝ HD comes standard with pivot style heads; however, upon ordering can be supplied with slide-heads which is designated as 7⅝ HDS. The 7⅝ HDS is part of our CHROMEBOSS® a series of tongs suitable for running corrosion-resistant alloy (CRA) tubulars. Two slide heads in the tong provide a consistent radial load on the tubular, reduced tubular deformation, and when combined with our pyramid fine tooth or True-Grit wrap-around dies provides excellent gripping capabilities on corrosion-resistant alloy (CRA).

Tri-Grip® Backup

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 allows 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 Dies when running drill pipe or optional Eckel Wrap-Around True-Grit® dies or Pyramid Fine Tooth dies for making up other types of tubular.
