This weakening of the springs or points of connection will often result in an unintentional explosive failure, flinging the damaged spring components across the garage and embedding them in the garage walls, vehicles, or other objects in the path of travel. Unfortunately, people were occasionally caught in the course of these explosive events. As the springs failed, several manufacturers invented a “caging” mechanism for the springs as a precaution. These cages were retrofitted onto the stretched springs in the hopes of capturing the pieces that would release if the springs failed. These shackles were useful, but they weren’t absolutely successful. Still now, some of these spring devices are in use. A certified technical service technician should be consulted if this condition occurs or the standard of garage components is in doubt. Try this Titan Garage Doors Coquitlam
A newer and safer method for opening the overhead garage door was developed in response to the potentially dangerous old style garage spring issues described above. The idea was to move the door’s load or weight to a vertical rod now fitted with a torsion (twisted) spring through a cable and pulley system. This sort of spring is attached to a fixed plate at one end and wrapped around a horizontal pipe with special hardware. Normally, this load balancing system is mounted directly over the garage opening’s header. The weight of the garage door is transferred into the torsion spring system using necessary wires, connectors, and pulleys. The way the spring energy is stored differs between the old model stretched spring and the newer torsion spring. The energy is collected and released by pulling on the spring or returning it to its un-stretched state with the old style stretched spring. The energy is imparted or extracted from a torsion spring by rotating it clockwise or counter clockwise, depending on the direction of use. The garage installer controls the total loading of the torsion spring during professional installation, which is determined by the weight and height of the garage door it is working.
