A pulling swivel is an essential component of a Horizontal Directional Drilling (HDD) machine used to facilitate the pulling or towing of drill pipes, product pipes, and other equipment during the HDD operation. It is designed to minimize rotational torque and frictional forces while allowing for smooth and controlled pulling or pushing movements.
The pulling swivel is typically attached to the drill rig or a pulling machine and is connected to the drill string or product pipe through a threaded connection or other suitable means. It acts as a rotational joint, allowing the drill string or product pipe to rotate freely without transferring excessive torque to the rig or pulling machine.
