Homeowners who have to replace a garage door spring often do not appreciate the complexity of the mechanism that opens and closes their door. When the spring breaks, they likely never heard the spring break or felt the door weight as much as a small car trying to move it again. It is often only at that moment that people realise just how much work a spring does in a garage door system.
Garage door springs are more complex than they appear at first because the design required for them to work properly is subtle. Garage door springs are used for more than just lifting a garage door. They are engineered to provide an exact counterbalance for the weight of a specific door with tight tolerances on the travel distance. The opening and closing mechanism of a garage door system relies on a precise amount of spring tension, not simply calculated or estimated, because the opener motor might wear out or because you want to manually operate your garage door. Using a garage door spring incorrectly can be dangerous. For Garage Doors Bristol, contact www.upandoverdoorsltd.co.uk
Torsion springs, in particular, are a type of spring that runs horizontally above and along a garage door system. They store an enormous amount of energy as they are wound, which provides the tension needed to lift the door. When one of these garage door springs fails unexpectedly, it can come down at high speed and cause serious injury.
The design behind the garage door spring is precise and load-specific and is often safety-critical. Homeowners do not always realise just how complex the design is until they have determined that something is wrong with their garage door system.
While the spring is probably the component nobody thinks about, everything else depends on it.
