Garage door springs play an important role of lifting and holding the door weight. Some springs are suitable for commercial heavy doors while others are designed to lift the lighter residential doors. Here are the major door springs:
Torsion springs make use of the torque to lift the door. They are securely attached to the spring anchor bracket by a stationary cone, present on one end. On the other end is the winding cone, which facilitates installation and removal of the springs. Springs in this category share the following qualities that dictate the weight and the number of times they can lift the door to open and close;
· Length of the spring
· Wire size
· Inner diameter of the spring
Major torsion springs models include:
Early set torsion springs
These springs are installed in the central part of the shaft. They are mounted on the torsion shaft near the cable drums on each side, using specific tools.
Standard torsion springs
These springs are normally found on residential doors. The standard torsion are installed above the door opening and supported by the shaft that runs through it. Seeking for professional advice is highly recommended in order to know the number of springs to be installed. However, lighter doors use one standard spring while the heavier doors use two.
Steel rolling door torsion springs
This model of springs is commonly installed in the commercial rolling doors. In order to support the doors using the rolling mechanisms, these springs are mounted within the torsion barrel
Torque master torsion springs
Torque master springs are mounted to run through the torsion shaft. They are well secured in place by the winding cone located at each end of the torsion rod. Unlike other springs that are easily winded using winding bar, torque master springs are only winded by a power drill.
One piece curtain door springs
These springs are commonly mounted to lift doors installed on storage units. Two springs are required to adequately hold the door weight. Each spring is fixed to the torsion rod present on either side of the door.
Standard commercial springs
This model of springs is similar to standard springs for residential doors, only that they are designed to lift heavy commercial doors. A shaft runs through the springs hence securing and holding it in the right position.
Extension springs are typically mounted in the residential doors. They are fixed above the upper tracks that run horizontally along the door. They extend and shrink for the door to open and close respectively. This movement provides a counterbalance force that lifts the door and supports it’s weight. Extension springs are secured by an eye bolt and S-hook that firmly fixes them to the beam present in the garage frame. Garage owners planning to install the extension springs should ensure that they are supplied with safety cables. This entails a pulley and cable system that guarantees safety in case of cable, spring or bracket failure.
