XK-150 for Heavier Jobs
For deeper, heavier jobs we offer the XK-150 with 12,000 ft-lbs and a 150-ton rating.
Like all our swivels, it has the simplicity of no gears. The only moving parts are the hydraulic motor, stem, and packing cartridge. Using a hollow shaft hydraulic motor, the swivel stem is driven directly by a massive lubricated spline.
Available lifting devices include elevator type bail or Cobrahook™ link hooks, which allow wire line lubricator access to the gooseneck top connection for horizontal drilling work.
BUnique features include power tilt, 10,000 psi washpipe seal assembly, powered hose reel which handles all hydraulic hoses, and optional brake.
It also includes our patented safety valve which prevents 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 - Two speeds not required.
12,000 ft-lbs torque - Higher than connection rating.
150 ton static and rotating load ratings.
Patented 10,000 psi Washpipe Seal Assembly - Auto-lubricated - Unique design for low friction and long seal life.
Patented Power Tilt - Tilt angle easily set at rigup - repeats throughout job. Automatically holds vertical when tilt not in use. Control valve on power unit swivel rack allows safe and convenient loading & unloading .
10,000 psi Washpipe Seal Assembly
Our patented seal assembly is rated at 10,000 psi. It is automatically pressure-lubricated and requires no manual greasing.
Field reports are so far at 1200 hours seal life before changing without failure. Interchangeable design improvements have continued but we have no field data yet. We expect seal life to continue to improve. This is a uniquely engineered and patented design, very different from other sealing concepts using a stack of brass rings and rubber V-rings of various compounds.
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 for easy stab with no need for a rope or chain.

XK-150 Power Units
XK-150 power units use a variable displacement piston-type hydraulic pump to allow any swivel speed desired. Caterpillar engines are standard, others optional.
Electric motor power is also available if you need to plug in.
Hydraulic-powered hose reel is standard with 100 foot hydraulic hoses, and reel will accept 200 feet if required. Axle rotates on standard high pressure Chiksan-type swivel joints, available economically anywhere in the world. For operator safety, our hose reel control valve is located well away from the reel. We proudly call the reel drive our ugly gear drive, so named because the slow moving open gears are flame cut, not machined, and require no lubrication.
Trailer Power Units
Our trailer power units are designed with the highest degree of roadworthiness. We use the widest tandem axles with oversize weight ratings. Electric brakes are fitted on both axles, and the standard breakaway system locks the brakes should the trailer separate from the truck. For best roadworthiness, all equipment is arranged on the trailer centerline. Rugged fender tanks are arranged on each side to maximize service access on the trailer deck. Gooseneck or bumper hitches are optional, and spare tire is included.
Skid Power Units
Rugged oilfield skids are designed for truck winching and are fully floored with diamond plate. Oil spill containment rail is fully welded all around. Heavy-duty dual tank design uses minimum floor space, and all equipment is arranged to allow easiest access for service. Heavy bumpers are standard on both ends. Offshore skids are built with overhead crane lifting frames, seal welding throughout, and special salt air paint systems.
Helicopter-transportable dual-skid units are available if required.
Air Remote Controls
Air remote controls are connected by a 50-foot control hose umbilical. 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 is also located at the engine.
Stainless control box for setting maximum torque is mounted on each unit near the pump with the same torque gauge as the main panel.
If your preset max torque is reached, rotation will stop and torque will be held.
Torque setting instructions are etched on front panel of the box.
XK-150 TORQUE REACTION
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 from falling objects. Optional parallel torque arms are arranged toward the back of the mast.
Also optionally, our patented top drive torque track can be fitted to the XK-150 power swivel with links and elevator.
