Usually the biggest mechanical thing around your house is the overhead garage door-the one that you push through your vehicle, sometimes without even opening it-I know you’re doing:-). For more details click Garage Doors In Tampa.
The key and most dangerous part of the overhead door is the garage door spring-( or springs depending on the design), which supports the entire weight of the door panels (sometimes more than 400 pounds) and allows you to lift / reduce the entire door brace. Personally, I have built 3 overhead garage doors with 2 different types of springs, and you have to believe me on that-garage door springs are under tremendous pressure and you can get seriously injured or even killed when doing these work. When you want to take your chances-follow directions to the last detail is imperative! Even if you’ve got a friend or a specialist doing this for you, read it and review it all after the installer has finished the job. There are no safety brakes at the garage overhead doors (at least I haven’t heard of any), which would keep it from falling down when the supporting spring fails. I noticed several U.S. patents for such devices, but obviously none of them have ever been applied to a garage door.
Garage overhead door-related accidents account for thousands of incidents each year (an estimate of 30000 per year), according to the US Consumer Product Safety Commission. Such casualties, for example, are: fractures, crushings, and amputations. Not all injuries are known to be recorded in the United States. (CPSC) There are essentially two types of garage door spring systems using tracks / side rails (at least the most common in Illinois and probably the rest of the United States): 1. Garage door torsion spring(s) wound-up on a rod above the garage door opening top (door header) section 2. Garage door extension springs that are mounted on either side of the door and extend along the horizontal part of the track when the door is closed You may also have an old, one-piece door that swings outwards as it goes up and overhead. This particular design will have springs placed on the sides of the door opening-secured to a lever bracket system at about your waist height, extending the springs towards the ceiling at the door closing. It is an ancient, extremely dangerous device which is no longer manufactured. If you have such a machine in the garage I would highly recommend that you repair it.
Garage door torsion springs-the spring designs are either single or double. Normally the spring breaks while under the highest tension that is when the overhead garage door closes / travels down, or is already completely closed (Normally). When you manually close it and it happens during this process, don’t try to prevent it from collapsing, let it go… Ok, unless that’s where your foot slams the door!
