Increase power and
torque by up to 45%
TDS-11HD
Higher torque and more power enables faster and deeper drilling,
even in the most demanding well operations
As the land drilling market demands high torque at high speed, contractors require top drives
that meet demands for 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. The 500-ton main
thrust bearing ensures hoisting capacity to handle heavy pipe. This means faster and deeper
drilling, both vertically and horizontally, to help you reach your pay-zone in even the most
demanding formations.
Offering the advantage of continued support through the global NOV network, engineering
and aftermarket, the TDS-11HD enables drilling of wells beyond the technical limits of the
standard top drive.
Contact your local NOV representative to learn how the TDS-11HD
can improve your performance.
