The Eckel 870 DPT combine power tong and cam-type hydraulic backup, providing a single piece of equipment to replace several...one smooth continuous operation instead of numerous time-wasting steps at each connection...and a quick, safe means of tripping, replacing methods that endanger crew members and pipe string a like. For drill strings up to 8 inch collars, the model 870 offers over 75,000 ft-lb of torque for break-out and make-up operations, plus ample speed for spinning joints.
