Garage Door. Monday , November 20th , 2017 - 03:42:05 AM
Canopy Doors: When a canopy door opens it swings outwards and then slides upwards into the garage ceiling. This leaves one third of the door outside the garage. The security of the door is enhanced as the pivot points are located down the door. These doors are easy to install as no tracks are required inside the garage and the entire door mounts to the door frame. Canopy Doors are available in timber, steel ABS and GRP. This garage door provides a good drive-through width.
As automobiles were invented and came into consumer market, there became a need to safely store them. At the time, outbuildings were a type of unattached garages that kept the horse and buggy. The original outbuilding held the transportation and all transportation related tools. So, consumers naturally begin storing automobiles right next to their horse and buggy in the same outbuilding. High society was the main consumers in the early 1900's and they didn't appreciate their shiny new car smelling like horse manure. A new solution was necessary to keep them happy.
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
