The Eckel 6-3/4 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. The model 6-3/4 will accommodate drill strings to 6-3/4 inches while giving the operator 50,000 ft-lb of torque. A solid investment in lower trip time...readily translated into lower costs on every hole.
