A movable barrier system for operating a movable barrier may include a torsion tube configured to rotate and a cable drum comprising a cable connectable to the movable barrier. The cable drum may be configured to rotate relative to the torsion tube. The movable barrier system may further include a sensor configured to detect the angular displacement or a force between the torsion tube and the cabled drum and send a signal when the angular displacement or the force changes. The movable barrier system may further include a controller in communication with the sensor and configured to stop rotation of the torsion tube in response to the signal.
