In simpler terms, they store energy when you close your garage door and release this energy to lift it open with minimal effort. There are two primary types:
- Extension Springs: Located parallel to the tracks on each side, these springs extend as you close the door.
- Torsion Springs: Mounted above the closed door, these coils twist and coil on themselves to provide lifting power.
Both types work by principles of physics – tension, and torque – to make lifting what could be hundreds of pounds feel almost weightless.
Guiding Hardware: Tracks, Rollers, and Cables
The smooth operation of your garage door also relies on several other key components:
- Tracks: These metal guides run vertically up from each side of your doorway and then horizontally across your ceiling. They provide a path for your rollers.
- Rollers: Fitted into brackets on each panel, they roll within the tracks, allowing for seamless navigation up and down.
- Cables: These run from bottom brackets on either side of your door up to drums located at each end of your torsion spring shaft. As your garage door closes, these cables wind around drums – storing tension that is then used to help lift your door.
Basic Working Principle
To encapsulate:
- You activate your garage door opener via a switch or remote.
- The motor powers up, driving your trolley along its rail.
- As this happens, springs release stored tension – assisting in lifting your heavy door effortlessly.
