The VK-150 Power Swivel is in oilfield usage worldwide, including Alaska's north slope, Wyoming, Texas, Oklahoma, Canada, Columbia, Bolivia, and Australia. These machines have made a solid name for themselves as a heavy duty, economical power swivel providing smooth, high torque. Since 1980, we have been known for rugged, simple hydraulic drilling equipment, and the VK- 150 fits right in with these design criteria.

With a 150 ton static load capacity, the VK-150 is also dynamically rated 97 tons at 150 RPM. Because of the large gear widths and hydraulic motor capacities the units are capable of being driven by up to 550 HP.

The two high-torque, fixed displacement, piston-type hydraulic motors have a high tolerance for contamination because of their low speed characteristics. These hydraulic motors and two pinion gears drive a central bull gear to provide torque ratings of 10,000 ft-lbs. or an optional 14,000 ft-lbs. The VK-150 uses a large thrust bearing, a rugged 4 1/2" tool joint connection, and a full length 3" bore. The full floating washpipe cartridge is quickly replaceable without removing the mud hose, and is rated at

5000 psi. The cartridge can also be installed inverted to allow greasing while rotating under pressure if desired.

The swivel is balanced to hang vertically, and is also balanced to allow easy tilting for stabbing the next joint of pipe.

Available lifting devices include our Cobrahooks™; these are link hooks which allow wireline lubricator access to the gooseneck top connection for horizontal drilling work. Hook-type and elevator-type bails are also available.

Standard torque reaction assembly is two telescoping torque arms for use with wire ropes tensioned vertically between crown and floor. These torque arms have steel wire rope sheaves for rolling contact with wire ropes.
