Garage Door Automatic Opener

Overhead Garage Door Opener 

The electrical overhead garage door opener was devised by C.G. Johnson in 1926 in Hartford City, Indiana. Electrical Garage Door openers didn't become popular until the Age Meter Business of Chicago offered one after the Second World War, where the overhead garage door could be opened via a keypad found on a post at a switch inside the garage or at the end of the drive.

Contrary to popular belief, the electrical opener will not supply lifting electricity to open a heavy garage door. Most of the real lifting electricity comes from the counterbalance springs. The electrical opener supplies a modest amount of force to control how much the door shuts and opens. Generally, the garage door opener holds the door shut instead of a lock.

The typical electrical garage door opener is made up of a power unit that has an electric motor. The power unit attaches to a course. The trolley is pulled along the track when a chain, belt use, motor, or screw turns. Limitation switches on the power unit control the space, and the garage door closes after the motor gets a signal from the remote control or wall push button to open the door and open it.

The whole assembly hangs above the garage door. The power unit hangs from the ceiling towards the back of the garage. The power head is generally supported by perforated angle iron.

Lately, another kind of opener, the jackshaft opener, has become more popular. This opener style includes a motor that transfers the door and attaches to the side of the torsion stick, down and up, by just spinning the stick. These openers need several additional parts to work for residential use. They have the advantage of freeing up ceiling space that a railing and an average opener would occupy. They also have the disadvantage that the door must have a torsion spring to attach the motor.
