The hydraulic, motor-driven Logan 120-ton power swivel provides smooth, shock-free torque. It is rated to support tensile pipe loads of 120 tons at zero rpm and 65 tons of dynamic load at 100 rpm. The compact, swivel-head design weighs only 2,000 lbs. and fits into most drilling or workover masts. Maximum torque is rated at 8,100 ft./lbs at 150 rpm maximum.
The design incorporates a reliable, custom drive train with hardened steel gears and eliminates the use of dangerous spinning chains, tongs, and kelly spinners in most applications. The power swivel reduces stops and start-ups, improving rig efficiency and reducing wear on the pump, drawworks, and other rig equipment.
