Usually, the largest mechanical thing around your house is the overhead garage garage door installation santa rosa – the one you’re driving your car through, sometimes without even opening it – I know that you do :-).
The major, and the most dangerous componnent 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 over 400 pounds) and helps you to lift / lower the entire door assembly. I have personally installed 3 overhead garage doors with 2 different types of springs, and you do have to trust me on that – garage door springs are under enormous pressure and you can get seriously injured or even killed when performing such work. If you decide to take your chances – it is imperative that you follow instructions to the last detail! Even if you have a friend or a professional doing it for you, read it and check everything after the installer finishes the job. The garage overhead doors have no safety brakes (at least I haven’t heard about any), that would prevent it from falling down when the supporting spring fails. I’ve found some US patents for such devices, but apparently none of them were ever implemented into an actual garage door.
According to the US Consumer Product Safety Commission, garage overhead door related accidents account for thousands of injuries every year (average of 30000 per year). For example, these injuries are: fractures, crushings and amputations. It is believed that not all injuries are reported in the United States . (CPSC)
