The standard electric garage door opener consists of a power system that includes the electric motor. The power system attaches to a record. A trolley joined to a handle that attaches to the head of the garage door slides behind and forth on the track, thus starting and closing the garage door. The trolley is picked along the track by a cable band or screw that turns when the motor is run. These combine a cable pressure monitor, to recognize when a cable is broken, and a separate locking device to block the door when it is fully closed.
