7⅝ HDS-25 Tong
When application demand a wide range of sizes, this tong handles pipe sizes 2⅜ inches all the way to 7⅝. Built around the 7⅝ Standard, the 7⅝ HD provides a thicker rotary gear for more added strength, an additional idler gear, a larger pinion gear, and stronger bearings for load bearing capacity and durability.
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® series of tongs that is 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-GritTM wrap-around dies provides excellent gripping capabilities on corrosion-resistant alloy (CRA).
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.
