Drive Drilling Equipment System
Top drive drilling equipment has many patent technologies.
The main features are:
Power swivel adopts AC motors, and driven by VFD system.
Power swivel adopts heavy duty thrust bearings and special structure design.
Link tilt assembly of pipe handler can be forward or backward and rotating which is useful to grasp drill pipe and make main shaft closer to rig floor when drilling.
Pipe handler equipped with backup tong, which is of wide clamp range. IBOP doesn't rotate with the tilt.
Integrated with mechanical, electrical, hydraulic and information technology, the automatization level is highly improved.
