The Mechanism of Modern Garage Doors

The Mechanism of Modern Garage Doors Have you ever wondered about the mechanism behind the operation of your garage door? When you reach home and press the remote control that opens the door automatically, do you think for a second about how it actually works? Perhaps this thought has crossed your mind a couple of times but you toss the idea around since you don’t know the exact explanation for it. Garage doors operate with a special mechanism that enables them to open automatically as you enter. This system has brought many people too much convenience that it would be unbearable to go back to the days when ordinary garage doors were not remote controlled. Beautiful wooden garage port doorways are definitely attractive and great for aesthetic reasons. However, operating traditional wooden doors is completely difficult. Can you imagine arriving at your house as the rain pours down heavily and getting out of the car to manually open the door up? It must have been a hard experience. To let you know about the mechanism of an automated garage door, here’s how it works. Once you press that button on the remote control, a signal is sent to the receiver located inside the garage. The normal frequency range for that signal is around 300 to 400 MHz. It’s termed as the rolling code which basically means that the code constantly changes each time you use the remote control to open the door. This makes it virtually impossible for burglars to crack the code. It may sound like a very complicated system; however, the simple part lies on the electronic opening of your door. The more complex parts are actually the hardware components like the springs. When you press the remote control button, the mechanism to open the door up begins, and the doors operate using chains or belts. Your garage port entry way ceiling’s motor begins to turn and pull the chain or belt in a clockwise direction. After this, the springs are pulled along with the track mechanism. Then, the door starts to rise. The process is basically the same when the door closes down, only that the chain or belt moves anticlockwise. Compared to old types of doors with up and over mechanisms, today’s automated garage doors are more secure. They have a limiter that instructs the door to stop upon reaching the top or bottom. Additionally, they come with a sensor which notices if there’s something in the door’s way. Thus, if your pet ever comes running towards you and halts at the door’s passageway, you don’t have to worry that your poor dog will be crushed. The door automatically stops upon detecting an object on its path. This makes modern garage doors very safe and convenient.
