• TDS-11HD

    The TDS-11HD increases power and torque by up to 45 percent compared to standard top drive models, enabling drilling in longer laterals and deeper wells.



    The TDS-11HD builds upon the field-proven performance and brand quality of the TDS 11SA top drive, offering extra power and torque for increased drilling requirements. Featuring two 600-horsepower induction motors plus gear box internals, the TDS-11HD yields more torque than previous top drive models in its size and class, enabling drilling of wells beyond the technical limits of the standard top drive. The 500-ton main thrust bearing ensures hoisting capacity to handle heavy pipe, helping you reach your pay-zone in the most demanding formations.
