Torsion springs are part of a sophisticated and exceptionally dangerous counter-balance system. On a two-car garage there are two commonly used systems, the first is a single spring system, the second is a double spring system. On a single car garage typically you will only find one-spring system, this is unless the garage door is exceptionally heavy. The springs themselves consist of the steel wi

re with a stationary cone at one end and a winding cone at the other end. The winding cone consists of holes every 90 degrees for winding the springs and two setscrews to secure the springs to the shaft. Never attempt to unscrew these setscrews as they are under tremendous amount of tension. Garage doors come in different height, widths, and weights; because of these differences it is extremely important to have the correct size torsion spring rated for the weight and height of the door. The wrong size garage door spring can cause personal harm to you, your family or property. Please let 24x7 Pro Service assist you with this. The garage door springs ride on a long tube called a torsion tube. The torsion tube transfers the energy from the garage door spring to a drum on each end. The pair of drums has a pair of cables that attach to a groove in the drum and run down to the bottom bracket on the lower garage door panel. The entire torsion tube system mounts on the header wall which is held up by two end plates and a center bearing plate above the garage door. There are two commonly used bearings for the center bearing plate. The first type is actually just a cheap nylon bushing which many companies use to save on their own expense, 24x7 Pro Service uses an actual steel bearing. A steel bearing has a much smoother action and a much higher life expectancy. Steel counterbalance cables run from the roller brackets at the bottom corners of the door to a notch in the cable drums. When the door is raised, the springs unwind and the stored tension in the torsion tube lifts the door by turning the tube, hence turning the cable drums, wrapping the cables around the grooves on the cable drums. When the door is lowered, the cables unwrap from the drums and the springs are rewound to full tension. The springs are under full tension when the garage door is down. This is why the springs typically break when the door is down. Garage door manufacturers such as Wayne Dulton, Amarr, and others typically produce garage doors fitted with torsion springs that provide a minimum of 5,000 to 10,000 cycles and are guaranteed for two to three years. One cycle is a single opening and closing sequence. 24x7 Pro Service offers a 30,000 cycle spring. It is important to remember that if the weight of the garage door is increased by adding glass, additional insulation, or even several coats of paint, the life of the torsion spring may be greatly reduced. The other factors that may reduce the life of a garage door spring are poor garage door maintenance, track issue, bent hinges or cheap components. A garage door has many moving parts and is the largest moving part of any home. This is why garage door manufactures typically recommend that a garage door tune-up be performed at least once every 6 months for a safe and trouble free operation.
