What Are The Function of Garage Door Springs?

Torsion springs and extension springs are kept under enormous pressure when the door is shut to assist it upwards once you want to open it. With torsion springs, this pressure is made by the springs being tightly coiled and compressed, usually by a metal cable drum that tightens the spring because the door is lowered. With extension springs, the pressure is made when the springs, which run parallel to the overhead tracks. are stretched when the door is lowered.

Without the springs, a garage door, which may weigh several hundred points, is almost impossible to lift and lower, either by hand or by the relatively small electric motors found on mechanical garage door openers. Lowering a garage door without springs may be a dangerous affair because the door can easily slam down violently.

In many installations, the garage door springs can last as long as 30 years, but like all moving metal parts, garage door springs will eventually wear out or break thanks to fatigue. When one of the spring breaks, your garage door will cease to work properly.

If you use the garage door by hand, you’ll notice that the door begins to feel very heavy to lift, or it’s going to slam down hard once you close it. If you’ve got an automatic garage door opener, the electric motor may pack up properly, unable to handle the load.
