Top Drive System

Brief Introduction:

Top Drive System integrates mechanical, electrical, hydraulic and information technology. It is an important drilling equipment that used to replace rotary table to provide rotary power.The maximum continuous drilling torque covers 22kN·m-85kN·m.

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.
