Power drilling swivel
Used for transmitting the rotation of the drill pipe upper part in drilling operations, and oil and gas well workover, including sidetracking.
The swivel comes with the power station providing the swivel shaft rotation with the established moment and smooth changing the rotation frequency and direction.
