General Information about Torsion Spring Mechanism System

To know about how do garage doors work, first of all, let us talk about the torsion spring system. This one is factually the mechanism system that is more common to use and choose for garage door opener. Usually, the torsion springs are installed above the door or on the ceiling horizontally. The springs will wind up when the door is closed down, giving the whole system energy. On the other hand, when the door is about to be opened, the same springs will unwind and by using the energy mentioned previously, these have enough power to lift the door open.

As long as the door is not closed and opened over time, this system mechanism will always work properly and there will never be problems like broken door where the springs are broken or the one that cannot be opened. The work would be even better when proper maintenance is also done to the door mechanism system regularly, including also by oiling some door parts to make the garage access works smoothly without any noise.

General Information about Extension Spring Mechanism System

The next type of mechanism system used in common garage door is called as the extension spring mechanism system. The way it works is factually quite similar to the way the other mechanism works explained previously. Although it is so, it cannot be denied that there is a rather big difference found in this one. The difference is located in the springs. These are not winded but stretched instead. This happens when the door is closed. On the contrary, when the door as access to the garage area is opened, the springs will be extended. It is quite the same also with the previous type in the way the mechanism, especially the springs, will be broken when the door is opened and closed too many times in a quite short period. That is why, even this mechanism is different, and the same treatment and maintenance is still needed to be done for better performance and longer durability.
