Garage Door Torsion Springs

Torsion Springs are mounted directly above the garage door opening, when the door is in the down position.
Torsion Springs

Garage Door Torsion Spring systems use a spring bar, also known as the torsion tube. The spring fits around this bar, and is mounted with tension.

How a Torsion Spring System Works

Once the garage door spring is mounted to the spring bar, it is loaded with energy, when the spring bar is loaded with energy from the spring. The bar is then called the torsion tube.

The torsion tube has drums connected to each outer end. The drums allow for a cable attachment point to the torsion tube. From these points the cables wind and unwind around each end uniformly, as the door opens and closes. The cables connect the bottom mounting brackets on the door to the torsion tube on each side.

Above is the most basic explanation of how a torsion spring system works.

If you take into consideration different applications such as the height, width and weight of different garage doors. The logistics can compound and become more complicated. Distributing the load of the door evenly when in operation, will allow for less strain on the entire system.

Some torsion spring systems have up to 4 springs to assist in operation. Once the basics of the mechanical operation is understood, safety in maintenance can proceed.

Without proper understanding and proper tools, replacing springs can become extremely dangerous and should not be attempted.

Torsion spring systems have been proven to be the most reliable, and most safe option of garage door spring assisted systems.
