Top Drive System Rated drilling depth 12,000 m Rotary speed 0~200 r/min
Descriptions of Top Drive System Rated drilling depth 12,000 m Rotary speed 0~200 r/min:
Top drive adopts heavy duty thrust bearings and special structure design.
Link tilt assembly of pipe handler can be forward or reverse and/or rotating which is useful to grasp drill pipe and make main shaft closer to rig floor when drilling.
Pipe handler is equipped with back up tong,which is of wide clamp range. IBOP won’t rotate when tilt.
The mechanical, electrical, hydraulic and electronic technologies are integrated to improve the automation level.
Related components confirm to API 8C.
