Garage Door. Saturday , December 09th , 2017 - 05:56:57 AM
The spring is perhaps the most undervalued part of a garage door initially but makes its value known very quickly. Low-cost doors tend to use extension springs. Make sure an internal safety containment cable is included in case of breakage. Springs tend to be the first part of the garage door to need service or replacement. Many springs are tested to operate between 5,000 to 10,000 cycles while some manufacturers make a spring that will last up to 30,000 cycles or more. That's a wide difference in longevity and value when you add it up. Most homeowners use their garage doors up to 3,000 times per-year so a 10,000-cycle spring could break within 3-4 years. Replacement usually costs $150 - $250. Check the manufacturer's warranty on the spring. Never buy a door with only a one-year warranty on the spring.
In response to the inherently dangerous old style garage spring issues as above, a newer and safer system for opening the overhead garage door was created. The idea was to transfer the load or weight of the door via a cable and pulley system to a vertical rod now equipped with a torsion (twisted) spring. This type of spring is installed with specialty hardware and bolts to a fixed plate at one end, while the entire spring is installed around a horizontal pipe. This load balancing device is normally installed directly over the header of the garage opening. Using appropriate cables, connectors and pulleys, the weight of the garage door is transferred into the torsion spring system. The difference between the old style stretched spring and the newer torsion spring is the way that the spring energy is stored. With the old style stretched spring, the energy is stored and released by pulling on the spring or returning the spring to its un-stretched condition. With a torsion type of spring, the energy is imparted or removed by rotating the spring clockwise or counter clockwise depending upon the direction of usage. With professional installation, the complete loading of the torsion spring is controlled by the garage installer, and is determined by the weight and size of the garage door that it is operating. When this type of torsion spring fails, it remains attached and intact to the location on the horizontal control rod where it was mounted. I have not heard of or seen any torsion spring fly across a garage, creating injury from failed components as with the stretched older style garage door springs. This is not to say that injuries have not occurred with the torsion style spring. The installation of this type of spring is generally safe when left to a trained garage door installation professional. Severe and serious injuries have occurred when untrained, unqualified individuals have attempted to install or service this type of spring. In most installations, a warning tag is left attached adjacent to the torsion spring when the garage door is installed. This tag warns of the danger associated with the stored energy of this spring, and alerts untrained individuals to not attempt any repair, adjustment or to even touch the spring and associated hardware. When the label that should be attached to this spring becomes damaged, is removed or tampered with, it is important that a new warning label be reattached immediately to show the dangers of this spring tension
The unique climate of the region brings stress to houses in Dallas-Fort Worth, and all of the cities around. Dallas homeowners are not strangers to fence and roof problems due to weather, as well as landscaping anxiety and lost windows due to hail. They also know that their garage doors undergo a lot of pressure. Their doors must be lasting enough to withstand possible hail damage on the surface of the garage door and the overhead door fixtures and hardware, warping due to extreme wind gusts and UV exposure, and parts malfunction from the high temperature fluctuations. If Dallas was voted as the city with the most weather hazards, then Dallas residents need the garage door with the most quality. This means that residents need to use special care when choosing which overhead door to acquire and which garage door company will be granted the installation job. If they don't order an overhead door that will endure the meteorological punishment of North Texas, they will soon regret it. Likewise, if they buy an overhead door of the highest quality, but use a new company that is unqualified and inexperienced to install the door, they may find their high quality door blown off, broken or split during the next wind storm. Improperly installed garage doors that come loose off the track during wind storms have been known to crash down on automobiles, or fly into neighbor's yards and cause property damage.
