Top Drive Unit
The TS-SINOTAI Hydraulic & AC motor powered TDU system features a compact design and rapid installation.
It is suitable for installation on both smaller and big rigs.
This system is driven by Hydraulic or VFD control system resulting in a greater range of torque speed capacity.
Other system components include an integrated swivel, bi-directional link tilt system, remote and manual blowout preventer valves, a backup clamp and a guide beam, etc.
