Generally, there are four kinds of garage door openers: chain drive, belt-drive, screw-drive, and direct drive. Obviously, they're distinguished by the mechanical drive they use to function.
The most common kind is the chain-drive. This cost-effective kind of garage-door openers operates by using a series, similar to a bicycle chain. It's the oldest, but still the most used type. It might not perform softly, but it still provides good value. The chain might develop loose over time, though. There are models that hide the chain, so making the chain drive garage door opener just a little more silent.
Belt drive garage door openers are using a steel-reinforced rubber belt, just like the fan belt of an automobile, rather of a sequence, lower and as a way to raise the garage-doors. This type is less cheap compared to the chain drive kind, but it works almost silently because there's no metal-on-steel contact. Since the rubber belt is sturdily built, belt-drive openers can elevate provide years of support, even the heaviest garage-doors, and often come with a lifetime belt warranty.
Screw-drive garage-door-openers are likely the simplest to install if you intend to go the do-it-yourself course, and they need hardly any care afterwards. This sort works on the long metal pole threaded to operate like a screw.
Drives will be for the last thirty years in use in Europe, but they've been just recently getting popular in the United States of America. A motor that drives it self along the fixed chain is being used by these. Easy to maintain, they appear to be quite reliable, as the warranty covers perhaps not only the motor, but the circuit-board, chain and rail at the same time. They can be as peaceful as the belt-drive openers.
Beside the degree of sound and the lifting power that they produce, their speed may be one of the most significant features. Having them come with lights can be significant in many instances.
No matter which kind you end up buying, make sure it has a rolling code safety attribute. Electronic ray that controls the safety is also essential.
Purchase a garage-door opener, say good bye to stooping and lifting!
