In 1921, the upward-lifting garage door was invented by C.G Johnson; he was also the man behind the invention of the electric garage door opener in 1926. A general garage door consists of more than one panel hinged together which a system of tracks which the help of roller. Torsion spring system or garage door springs play a vital role of balancing the weight of the door.

Mechanism of a garage door spring:

A garage door spring or torsion spring system which counterbalance the weight usually consist of one or maximum two very tightly wound up springs on a iron shaft with cable drums at both of its ends. The entire system placed on the garage wall above the garage door and generally has no less than three supports. A center bearing plate with an iron or nylon bearings and two end bearing plates one at the each end.

The garage door springs are consists of the steel wire with a non-moving cone at one of its end and a cone which can wind at the other end. The non-movable cone is generally attached to the central bearing plate. The cone which has the ability to wind is consists of hole at a distance of every 90 degrees for the winding of the springs and two sets of screws to make sure the springs to the shaft.

 

The counterbalance cable which is made up of steel run from the roller brackets which is placed at the bottom of the corners of the door to a notch which is at the cable drums. The springs unwind when someone raise the door. When the door comes down, the cable unwinds from the drums and the springs rewound to regain its previous position of full tension.

 

Lifespan of a torsion spring:

Generally the springs fitted by the door manufacturers, door dealers produce and sell torsion spring which comes fitted with garage doors support a minimum of 5,000 to 1000 cycles. One cycle means a complete round of opening and closing of the garage door. With a life span of 10,000 to 15,000 cycles the springs generally allows the garage owner to close or open his or her garage from 3 to 7 years. If the owner puts some extra weight on the door by painting several times of fitting glass then that could reduce the lifespan of a torsion spring.

 

Maintenance of a torsion spring:

It is the responsibility of the owner of the garage to check the door of the garage monthly. If someone faces any obstacle at the time of raising or lowering the garage door or the door doesn’t remain stationary at the highest point then he or she should conclude that the balance of the door has been disturbed and should be checked. Then he should ask an expert mechanic to rebalance the springs of the door or replace it, if needed.

Along with that one should never forget to lubricate the garage door springs regularly for the frictionless movement.

Garage Door Torsion Springs

Garage door torsion springs as the name suggests finds a utility in the overhead garage doors. In a garage door, the torsion springs play the role to balance the weight of the garage door. First time C. G Johnson made a upward lifting garage door in 1921 and again went ahead to invent electric garage door openers in 1926. There are several kinds of garage doors now available in the market.

 

Single panel garage doors

Single panel garage doors, which is constructed from a single monolithic panel. Single panel garage door has a disadvantage. When the door is opened the panels of the door swing upward in an arc and get deposited at the top of the door and bulges outside of the door. That means the vehicle has to stop in front of the door at a distance, otherwise there is a chance of getting damaged by the arc formed by an upward going door. Incase of sectional doors, there are six to eight numbers of panels instead of one in case of single panel door.

Sectional garage doors

Sectional garage doors have some advantages over the single panel garage door. It has more strength in comparison to single panel doors and a vehicle can park close to the door at the time of entering into the garage as there is no danger of being get damaged by the garage door. Roller doors are usually made up of corrugated steel, though other materials can be used for its manufacturing. These kinds of doors specially find a place for the commercial use but there is also a disadvantage here, these kinds of doors can not be insulated perfectly.

Garage Door Spring guide

No matter what kind of door one is using for his or her garage but there are garage door torsion springs are present in every kinds of garage doors. And it is the torsion spring which is responsible for the upward and downward movement of the garage door.

And door torsion spring is the only part which requires a constant maintenance. Usually the torsion springs comes with the garage doors have a usual life span of 10,000 to 15,000 cycles, where a cycle means closing and opening of the door once. So, with a life span of 10,000 to 15,000 cycles, torsion springs can help the garage door to function smoothly for almost 3-7 years. After that these may need replacement.

 

If someone doesn’t able to open his or her garage door easily as he or she should or the door doesn’t stay stationary at its upper position then he or she should go to an expert mechanic and ask him to check the garage door springs. If those are in good condition then he would rebalance those or he will ask to replace those.

Then the owner should act according to the mechanic for the sake of his or her garage door and for the sake of his or her vehicle. If one able to keep the torsion springs of his or her garage door well, then his or her garage door will remain well.
