TDS-10 Top Drive The TDS-10 Top Drive is a single motor top drive developed for use in a variety of land and workover rig applications. It generates 350 HP with a hoisting capacity of 250 tons and a continuous drilling torque rating of 20,000 ft. lbs. The TDS-10 has a maximum speed of 182 RPM and makeup/ break-out torque of 36,500 ft. lbs. Because of the broad speed and torque range of AC motor technology, this impressive performance is obtained using a single-speed gear box.

The TDS-10 Top Drive system is driven by a Variable Frequency Drive (VFD) control system for a greater range of torque and speed performance. System components include an integrated swivel, bi-directional link tilt system, remote and manual IBOP valves, back-up clamp for breaking out connections, guide tube for reacting drilling torque and an electric service loop. A compact integral power unit mounted on the top drive eliminates the need for hydraulic service loops. And the short overall height and rapid-installation guide beam design of the TDS-10 ensure easy installation in existing masts or derricks.
