Anatomy Of The Garage Door System

I’m sure you’re just dying to know how the garage door works on a mechanical and electrical level. Thanks to the genius workers at Reliable Garage Door Repair, you can know the inner-workings of a garage door without having to get your hands dirty! Let’s start with the primary source of the lifting strength in a garage door: The Torsion Spring.

The Torsion SpringAnatomy Of The Garage Door System

A garage door usually dies sometime around its 13,476th operation. It’s not a dramatic ending, nor is it very pronounced, it simply occurs because it’s time. Sure, factors played a part in bringing its life expectancy a little lower than the factory predicted amount of time; maybe it was that freeze you had recently that swelled up the doors, or perhaps that one time it closed over something it shouldn’t have, either way, it was time for the garage door to meet it’s end, and that’s what it did. What really met it’s end though, is most likely the torsion spring. This spring is located at the top of your garage door. With it, your motor finds the leverage it needs to lift the door out of a stopped and sitting position. The main controlling mechanism within the garage door’s mechanical infrastructure is the torsion spring, not the motor inside the box at your garage ceiling.

Main Components of The Garage Door Opener

There are 3 main components to a garage door that allow it to work properly.

First, the motor and gears: This dual-entity mechanical unit is hooked up to a 120-volt-outlet which is generally about all it takes to overcome the inertia of a stopped door. This machine also does all the work when it comes to keeping the door from crashing to the ground when it closes.

Secondly, you’ve got a drive track, or also more affectionately referred to as the T-Rail in your garage door opening system. This drive track is connected with a chain, and it pulls your door up and along the specified track of the garage door.

Thirdly, you’ve got a component called the inverter that pulls the regular household AC power and converts (or inverts) it to DC power. This DC power is then directed towards the battery of the unit. The DC converter also powers a backup battery that kicks in if the power of the house happens to go out.

Different Types of Pulley Systems, and Codes

Many different types of pulley systems have been used. People have used belts, chains, and even screws to accomplish their task. Today, the most common of them all is a chain. The reason for this is that it is less effective by the weather, and less able to become damaged due to use.

In the old days, the garage door unlock receiver, meant to communicate with the opener, transmitted just one code in all of its life to open the garage door. Nowadays, the garage door opener code is changed each and every time you remotely transmit the signal code to open or close your garage door. This way, hackers can’t grab that code out of the air and use it when you’re gone.
