ABOUT GARAGE DOOR OPENERS

There are two main types of automatic garage door opener. The first, known as the trolley actuator, comprises a motorized trolley which runs along a rail fixed to the center of the ceiling of the garage. The trolley is attached to an arm attached to the door, and as the trolley moves back and forth the garage door opens and closes. The second type, is the jackshaft. This attaches to a spring shaft at the side of the door. Because it is located at the side of the door it does not take up space below the ceiling of the garage. This enables space to be left to accommodate high vehicles. In all cases it is important that the garage doors are properly counterbalanced with springs or weights, to avoid undue strain being placed on garage door openers.
