In 1999, our XK-90 power swivel launched with the simplicity of no gears.
By 2008, with its high tonnage and torque ratings, it had become the preferred power swivel by well servicers around the world.
By 2015, it had evolved to the current XK-100 with 7000 ft-lbs torque and a 100-ton load rating. Many other unique features include power tilt, 10,000 psi washpipe seal assembly, powered 4-hose reel which handles the hydraulic hoses, and optional air brake. Our patented safety valve is also included to prevent downtime from blown shaft seals if someone forgets to hook up the drain hose.
20 years in the field - 3rd generation design - same compact size
Variable speed, zero to maximum - 2 speed hydraulics not required
7,000 ft-lbs max torque - Higher than 2-7/8" IF connection rating
100-ton static load rating - 99 tons rotating load rating
Patented 10,000 psi Washpipe Seal Assembly - Unique design - Auto-lubricated for low friction and long seal life - no manual greasing
Patented Power Tilt - Max tilt angle easily set at rigup - Tilt then stops at same angle throughout job. When tilt not in use, unit stays in vertical position hydraulically, no rope or chain required. Local tilt control valve on power unit transport rack assists safe loading/unloading.
Patented Safety Valve - Prevents downtime if someone forgets to hook up the drain hose.
Only four hydraulic hoses required - All on one powered hose reel
Optional Air Brake - More brake torque than swivel torque
High-Pressure Seal Assembly
Our patented seal assembly is rated at 10,000 psi. It is automatically pressure-lubricated and requires no manual greasing. Quite different than other sealing concepts, this is a uniquely engineered approach.
Our seal assembly has been lab tested at 7,500 psi for 1,000 hours, and seals looked good. But lab testing is not field testing, and after two years in the field, reports are at 500 hours seal life. The next generation of improvement parts have already been installed in all units in the field (appx 50), but we have no data yet. Two more big interchangeable improvements are almost ready and will be installed on every new unit. When life data is available, we expect more than 1,000 hours of seal life before replacement.
XK power swivels include our patented power tilt function. Our customers are very pleased with the safety benefits and time savings. The driller easily sets the max tilt angle at rigup to match the pipe angle in the V-door, then the tilt stops at the same angle during the job. When tilt is not in use, the power swivel is automatically held in the vertical position without rope or chain. Only four hydraulic hoses are required for all swivel functions, all on one powered hose reel.

XK-100 Power Units
Trailer Power Units
Two-axle trailers are arranged with rugged fender tanks for best road balance and serviceability. Units have electric brakes on both axles. Gooseneck or bumper hitches are optional, and spare tire is included. Hydraulic-powered 4-hose reel is standard with 100 foot hydraulic hoses, and reel will accept 200 feet if required. The unit also includes a variable displacement piston-type hydraulic pump to allow any swivel speed desired. Caterpillar engines are standard, others are available.
Skid Power Units
Rugged oilfield skids are designed for truck winching and are fully floored. Heavy-duty dual tank design uses minimum floor space, and all equipment is arranged to allow easiest access for service. Hydraulic-powered 4-hose reel is standard with 100 foot hydraulic hoses, and reel will accept 200 feet if required. The unit also includes a variable displacement piston-type hydraulic pump to allow any swivel speed desired. Overhead lifting frames are available for offshore crane lifting. Caterpillar engines are standard, others are available.
Air Remote Controls
Air remote controls are connected by a 50-foot control hose umbilical. Fully stainless control panel features liquid-filled torque gauge, single handle control for variable speed & direction, auto-throttle, and power tilt. Also included are engine kill (fuel shutoff), emergency engine kill (air shutoff), plus torque release control which allows controllable unwind of the drill string before picking up. Emergency engine kill can also be operated at the engine.
Stainless control box for setting maximum torque is mounted on each unit near the pump with the same torque gauge as on the main panel.
Torque setting instructions are etched on front panel of the box.
Torque Reaction Equipment and Rigup
Two telescoping torque arms are included with every unit, and several length ranges are available.
Four oil-impregnated nylon sheaves roll up and down wire ropes stretched between crown and floor.
Safety cables protect rig floor people from falling objects in case anything was to come loose.
Optional parallel torque arms are arranged toward the back of the mast which moves the wire ropes out of the way.
