Torsion springs are essential to the proper working and overall performance of your garage door. It is important to know a few things that would ensure you are optimizing the use of your garage door.
Here are some pointers to put you on the right track with regards to your garage door torsion springs:
Use Torsion Springs with Similar Dimensions
In a situation where you have a dual torsion spring mechanism garage door with a couple of torsion springs that are not of the same relative dimension, you may want to convert to having a pair of torsion springs having a similar dimension.
Using torsion springs with dissimilar dimensions is still possible. However, in order to optimize the life cycle of your pair of torsion springs, you would need to use springs with similar lengths, inside diameter and wire size.
Torsion Spring Life Cycle
When it comes to the life cycle of your torsion springs, you should know that it simply means the amount of times you need to own and close your garage door before the springs break. Note that one (1) torsion spring life cycle is calculated as the complete opening and closing of your garage door. Typically, torsion springs come with a life cycle rating which gives you an idea as to when you should consider replacing the torsion springs in the future.
However, the life cycle is only a guide as your torsion springs are exposed to the elements (rain water, snow and sunlight) which can all have a damaging effect on the springs. The steel of the springs may chip or may be corroded by nature. This can lead to the premature failure of your torsion springs before the expiration of their life cycles.
On the average, the standard life cycle of many torsion springs is set at 10,000 cycles. If you intend purchasing torsion springs ensure that their life cycle is not rated below 10,000 cycles. Note that if your intention is to have torsion springs with a life cycle over 10,000 cycles, then your wire size would need to be much larger.
With a large wire size, your torsion springs take longer to break. This is because the steel is thick and therefore requires an extended period of bending for the springs to break.
Also, make sure that an increased wire size comes with a corresponding increase in the overall length in order to maintain a similar torque and lift rating.
If your garage door is heavy and narrow, you may also need to have the inside diameter increased as well. This will ensure that the space on the shaft is sufficient enough for the torsion springs to be fitted in.
