The encoder used in the Varco TDS-11SA top drive sometimes does not require feedback from the encoder signal when drilling together, but it must be provided by the encoder when connecting and loosening the drill pipe threads, because the torque transmitted by the top drive needs to be adjusted with the speed signal to be smooth and stable.

The link tilt clamp is a critical part of the hydraulic system, allowing the articulation of the linked components to provide flexibility and movement for the equipment. The 350-ton capacity indicates the load rating or capacity of this particular link tilt clamp. EVERGROW supplies the NOV TDS-11 SA
