Retrofitting the garage door operator

Forget about ever having to get out of the car again to open the garage door
In bad weather conditions, and especially as winter approaches, manually operating a garage door is often nerve-racking. So why not retrofit the garage door with an electric garage door operator? Existing garage doors can also be conveniently opened and closed by radio using a door operator.
It's snowing, stormy or pouring with rain and still you have to get out of the car to open the garage. Then you have to close the garage again, in bad weather, with your hands full of shopping. With an electric garage door opener, you can easily control your garage door. Control is achieved using a transmitter or a smartphone app. This allows you to open and close your door at the touch of a button. We explain how a garage door operator can be retrofitted and what you should look out for.
Retrofitting the garage door operator: When doing so ensure:

To retrofit a garage door opener, you should find out how big your door is and its approximate weight. Depending on the door type, weight and size, you will need a suitable electric motor, that has the necessary pull and pushing force to open and close the door. Common garage door types are sectional doors, one piece doors and roller doors. Hinged double doors are used less, but can also be retrofitted with a door operator; special fittings may be required.
In principle, an electric garage door operator can be retrofitted to any garage door. It does not depend on the technology. The motor only replaces the manual force required to open the garage door.
Automate existing garage door
Garage doors have their own system in which they are guided. This system is still necessary and ensures a correctly adjusted garage door. This is important, because an incorrectly adjusted door can lead to a heavy load on the operator motor and to unpleasant noises. In addition, a door that does not run freely and is sluggish reduces the service life of the operator and the door fittings. The garage door should open and close easily by hand. If a mechanical locking device is present, it must be removed or shut down, since this task is performed by the motor.
A garage door operator requires some space under the garage ceiling. Under certain circumstances, a SUV, pick-up or off-road vehicle, which up to now barely fitted into the garage, no longer has enough space in height.
When retrofitting an electric garage door operator, also take safety into account. Power-activated doors are machines and, as such, the requirements of the Machinery Directive must be met. SOMMER door operators are developed and manufactured in Germany and comply with the latest international standards For example, an electronic motor monitoring system monitors the closing forces in accordance with EN 12453 and thus ensures greater safety.
