Your garage door has many parts working together to make it possible for your door to open and close. The spring or springs, shaft, and drums work together to form an assembly referred to as the counterbalance. This is why the team at Neighborhood Garage Door of Bay Area recommends you only use an expert to change out your springs.
The counterbalance helps make it possible for just about anyone to be able to lift the huge garage door up and over their heads. The job of the counterbalance is to counteract the force of gravity pulling on your garage door. When the tension breaks, it can cause damage to you.
How Does It Work?
Most doors are connected by hinges and ride on rollers guided by vertical and horizontal tracks. There are cables on each side of the doors that are connected to brackets at the bottom of the door. The cables only lift the bottom section of the door and the other sections are stacked on top of each other.
What the Cables Do
When the cables lift the bottom section, the other sections are lifted as well and eventually will push the other sections into the horizontal tracks. One end of the cables are connected to brackets at the bottom of the door.
How The Drums Work
The other end of the cables is locked into a slot on the drum. The drum is locked into a shaft with screws. This is for each side of the garage door. The two drums attached to the same shaft operate as one single rotating assembly. This allows them to both reels in the cables at an equal rate so that both sides of the door raise and lower at the same time to keep the door level.
The stationary end of the spring is bolted to a bracket that is anchored to the wall. The other end has what is called a winding comb. This allows the spring to be wound and has set screws that fasten the spring to the shaft after it is wound. The cables now link the door to the counterbalance and will keep the spring from unwinding. The drums keep all force of the door from the spring onto the cables.
As the door goes up, the spring will unwind and get progressively lighter. This will help keep some of the pressure off the cables and onto the horizontal tracks and the spring. You want to make sure the cables stay tight when the garage door is fully opened. When the door is in the down position, the weight goes back onto the cables and rewinds the spring.
The Lifecycle of Torsion Springs
As the garage door is opened and closed over time, the springs can start to weaken and the door will gradually becometooo heavy, rendering them less effective. The springs will eventually break, which will keep the door from opening.
Cold weather and rust can also affect the springs. One good thing is that the torsion springs can last between 5-7 years, and about 10,000 cycles. So, if you use your door 3-5 times per day every single day, you should get the normal use out of your door and not need to replace your springs.
