The rotary table is the element that ensures the transmission of the rotary motion from the rig to the drill string.

The basic functions of the rotary table are:

  • Transmitting the rotary motion and the torque required by the drill bit from the rotor by means of the kelly bushing to the kelly located in the upper part of the drill string;
  • Taking over the load resulting from the drilling string, respectively the tubing column, by supporting them during the maneuvering operations ( introduction, extraction and rotation of the drilling string when screwing and unscrewing );
  • Blocking against the rotation of the drill string, respectively of the tubing column, during the operations of tightening the rods or pipes;
