What Are Torsion Garage Door Springs?

Why Are Torsion Springs so Dangerous?

A torsion spring is used to provide support and cushion movement in a garage door mechanism. There are 2 distinct kinds of torsion

garage door springs. The first is in fact not a spring at all, it has torsional or spring-like properties and is a torsion bar. The second one is a helical-wound spring, which is commonly seen in mouse traps.

A torsion bar is normally used on automobile chassis, and trailer suspensions. The long spring, like the ones seen found tightly wound on overhead garage-door axles, is another kind of torsion spring. While a basic coil spring is designed to be compressed against a load or stress, a torsion spring works by twisting against itself while placed in a horizontal position. This twisting causes the coil to wind tighter, which in turn provides the power for the spring to work.

As the helix is wound tighter, it retains energy in the numerous coils which go to make up the spring. Once it is released, the spring will snap back to its original wound position. When these are used in a garage door, the torsion spring provides the energy to help open the garage door. This spring is wound tightly around the top part of the garage door.

This is an extremely dangerous operation due to all the pent-up energy, and could seriously injure or even kill anyone should it snap. The amount of pressure which is placed on the torsion spring must be just enough to make the lifting of the garage door seem effortless. However, should these garage door springs be wound too tightly, it could pose a potential danger to the door, the user or both should it break.
