Consists of large common oil supply tank, oil cooler, hydraulic pumps, filters, control valves, cylinders, and
all necessary plumbing.
Tophead Rotacy:
Hydrostatically powered tophead rotary with an infinitely controlled rotation speed of 0 to 120 RPM and a
maximum torque of 70,000 in-lbs.. Unit has a low torque mode, controlled from operator's station for use
when spinning out pipe in carousel. Air/fluid course is 2-1/2 in. diameter. Equipped with a floating sub to
allow smooth drill pipe connecting and a clamp for attaching wear sub. The stroke of the pulldown and
holdback cylinder allows the head to travel 29 ft. up and down the mast.
Mast and Crown Block:
Constructed of square steel tubing and structural steel electrically welded. Equipped with cable sheaves and
guide tracks for tophead rotary which allows tophead to retract off center line of hole. Retracting the
tophead allows 35 ft. working space above breakout table. The mast is raised and lowered by two hydraulic
cylinders. Equipped with a hinge mounted hydraulic breakout cylinder located above breakout table.

Indexing is manually controlled from working platforms.
Pulldown/Holdback:
The pulldown holdhack system powers the tophead rotary in either the pulldown mode or the holdback
mode through the use of heavy-duty cables and a 6-1/2-inch hydraulic cylinder. Pulldown mode provides
25,000 Ib. with a feed rate up to 85 FPM. Holdback mode provides 40,000 lb. with a pull out rate up to 90
FPM.
Winch on Mast:
Hydrostatically driven winch mounted on the mast for the purposes of tripping and pipe handling with jib
boom. The winch is driven through a heavy-duty gear reducer. Rated working capacity is 40,000 lbs. with
2-line reeving and line speed of 200 FPM on bare drum. Design allows for power-up or power-down.
