Garage Door Torsion Springs
What is Garage Door Torsion Springs
The Garage Door Torsion Springs is a large coil that helps lift and lower the garage door. By correctly installing and adjusting the spring, the homeowner only needs to manually move the spring up and down a little before it takes over to start the door. The automatic garage door opener will start the door for you, but the spring still plays a practical role in lifting.
There are two basic types of garage door springs: torsion spring and tension spring. They are used with two basic types of garage doors. The split rolling shutter door uses two torsion springs on both sides of the center of the top of the door. The upturned garage door uses two extension springs, which are installed on the extended swing arms on both sides of the door.
When the garage door spring extends, it bears huge tension. If it fails, it may cause the garage door to fall onto the vehicle or person. Unfortunately, most people do not know that springs, rollers, rails, arms and other parts of the assembly require occasional routine safety checks. Corrosion, loose hardware or worn parts may cause accidents, and improper spring adjustment will make it difficult to lift the garage door, or conversely, it will fly away from your hand.
Springs come in different lengths to accommodate various standard sizes of doors, from a single garage door to a double door. The tension provided by the spring is related to the weight of the door. The weight of the door can reach 400 pounds (181 kg), so it is essential to select the correct garage door spring if the door is to work normally, safely and easily.
Many people doubt whether replacing the garage door spring is a DIY (do it yourself) job. Experts stressed that this is not, and should be left to experienced technicians. Those who try to replace the spring may lose control of the spring or cable under tension, eventually leading to disability or worse. The local home improvement center usually reserves various types of garage door springs, and many will provide professional services to install these springs for you.
