Torsion Spring Lift Mechanism

The torsion spring lift mechanism of a garage door pertains on how the garage door is operated if it employs torsion springs instead of extension springs.

Torsion springs are tightly wound springs that are situated above the door opener. In every garage door, there can either be one or two torsion springs, depending on the door’s mechanism and weight. Torsion springs are one of the most dangerous components of a garage door that is why a torsion spring lift mechanism is employed so that homeowners do not encounter accidents and injuries while trying to repair or replace their door’s torsion springs.

Torsion springs have cable drums on each end, which are connected to a metal tube on the door. Torsion springs are made of durable metal wires but are flexible enough to stretch up to their capacity. When the door is closed, the springs are on their relaxed state. And during the opening of the garage door, the springs stretch themselves to their full capacity, enabling the door to be lifted to its full height.

The life of a torsion spring lasts for several years, but if homeowners continuously add other accessories to the garage door such as glass, extra insulation and even more layers of paint, its life can be significantly reduced due to more weight that it has to lift over time. They are capable to lift and lower doors to their full strength up to 15,000 times. Torsion springs, as well as extension springs, only have a set weight capacity that they can lift, so if you keep adding weight to your door, they will work overtime and as a result weaken themselves way before their time is up.
