Usually, overhead garage doors come with a single torsion spring and less often with a pair of these. The spring is mounted over a thick metal shaft which is fixed on the wall above the door. In the traditional design, the component is in the center. There is a drum on each side of the shaft and a cable over each drum. The job of the spring is to counterbalance the weight of the door. When the door is closed, this component is loaded with force and helps to keep the unit in place. When the door is opened either with the opener or manually, the force is released and applied to the drums and cables, which work to lift the unit.
Due to the great amount of force which it holds and the huge amount of work which it does, each garage door spring gets weaker every day. It will break eventually, unless it is replaced in advance. When it snaps in two, there is loud bang because the force is released. After that happens, you will not be able to open the door. In general, you must not use a door with a broken spring as this poses a huge safety risk and the risk of damaging the cables and rollers too. The replacement process involves removing the pieces of the old component and mounting the new one over the shaft. The winding is all about loading the spring with enough force to counterbalance the door.Back To Our Services
