  • Patent number: 10407497
    Abstract: A stuffing box loosening device for loosening a locking collar securing a stuffing box to a well head. The device includes a rotatable clamping tool having a clamp securable to an external surface of the locking collar. The clamp prevents relative rotational movement between itself and the locking collar. A force-receiving body extends away from the clamp. A main frame has a mounting portion securable to the well head, and the mounting portion prevents relative rotational movement between the main frame and the well head. A force-supporting body is attached to the mounting portion. An actuator is mounted to the force-supporting body and in operation extends to displace a second end to engage the force-receiving body of the clamping tool and apply a force thereto. The force rotates the clamp to loosen the locking collar.
