A Garage Door Controllers is a motorized device that opens and closes garage doors controlled by switches on the garage wall. Our garage door openers can also include a handheld radio remote control carried the owner, which can be used to open and close the door from a short distance. Did you forget to close the garage door when you left? A smart controller can send you an alert so you can take care of it on your way down the street.
The electric overhead garage door opener was invented by C.G. Johnson in 1926 in Hartford City, Indiana. Electric Garage Door openers did not become popular until Era Meter Company of Chicago offered one after World War II where the overhead garage door could be opened via a key pad located on a post at the end of the driveway or a switch inside the garage.As in an elevator, the electric motor does not provide most of the power to move a heavy garage door. Instead, most of door’s weight is offset by the counterbalance springs attached to the door. (Even manually operated garage doors have counterbalances; otherwise, they would be too heavy for a person to open or close them.) In a typical design, torsion springs apply torque to a shaft, and that shaft applies a force to the garage door via steel counterbalance cables. The electric opener provides only a small amount of force to control how far the door opens and closes. In most cases, the garage door opener also holds the door closed in place of a lock.The typical electric garage door opener consists of a power unit that contains the electric motor.
