Power Swivels
The newly engineered, hydraulic motor-driven Logan 85-Ton Power Swivel provides smooth shock-free torque and reduces drill string damage. It is rated to support tensile pipe loads of 85 tons at zero rpm and 45 tons dynamic load at 100 rpm. The compact, swivel head design weighs only 1,163 lbs. and fits most drilling or workover masts.

The design incorporates a reliable, custom-built drive train with hardened steel gears. For most applications, the Logan 85-Ton Power Swivel eliminates the use of dangerous spinning chains, tongs, and kelly spinners. The Power Swivel facilitates drilling with longer drill string lengths before the rig must be shut down to add pipe. Stops and starts are thereby reduced — improving rig efficiency and reducing wear on the pump, drawworks, and other rig equipment. The Logan 85-Ton Power Swivel utilizes a closed loop hydraulic system with variable displacement, reversible over-center pumps, and air or electric controls. A new wireless remote with an operating range of 150 feet is also available at additional cost. Speed control is continuously variable over the entire operating range. Maximum operating speed is 155 rpm. Pressure compensating type torque control overrides the speed control to maintain maximum torque at 3,950 ft-lbs. Torque limits on the power unit can be set, eliminating the potential danger of twist-offs or swollen boxes in the drill string. An integral rotary swivel bearing, floating washpipe assembly, and gooseneck connection eliminates the need for a separate rotary swivel.

A 2-1/4-inch bore gooseneck and washpipe assembly allows circulation through the 2-inch I.D. stem while rotating or in static mode. An access plug allows wireline to be run through the unit. Complete Power Swivel packages are available either trailer- or skid-mounted. Both frame styles are equipped with increased environmental safety features. Package components include an elevator-type bail; a unitized washpipe packing box assembly; a fixed displacement, piston-type, hydraulic motor rated at 5,000 psi; a torque rein assembly; safety cable; and one-inch swivel joints. Powered hose reels complete the rugged unit. A swivel carrying stand is standard. A variety of engine and control options, and additional accessories are available at extra cost.
