They are doors that work compensated by springs installed on their upper shaft, provided with two side pulleys, where they wind the steel cables, which are fixed to the lowest part of the sectional garage door, facilitating the climb. When we make the opening, the wire is wound on the pulleys thanks to the tension of the springs, and when it is lowered, it is unrolled by tensioning them again.
This means that in the case of not being automatic, that is to say, that they work manually, it facilitates the ascent, by not having to carry the full weight of the sectional door.
