Garage doors can be operated manually (by hand) as well as automatically (by power assisted motor). In both cases the proper operation of the garage door is determined by the proper balancing of the garage door weight springs and related component hardware. An automatic power assisted motor cannot overcome an improperly balanced garage door. The weight of all garage doors is normally deceptive. Due to the fact that a properly functioning door appears easy to open and close many users do not realize the combined overall weight until springs fail to assist the door in its operation. In all cases regardless of the type of garage door the entire system of hinges track hardware and door opener work as a team. Problems with misalignment shifting or jamming can lead to problematic operation of a door. Counter forces imparted to a garage door not engineered into the components can lead to injury. Inappropriate maintenance or complete lack of maintenance has lead to severe bodily injuries. Forcing the operation of a garage door when one or more components have become damaged or broken has lead to serious bodily injuries. In all cases maintenance is a crucial and important aspect of proper operation of all door systems.
This weakening of the springs or points of attachment would often lead to an inadvertent explosive failure flinging the broken spring components across the garage embedding the spring or steel components into the garage walls cars or other items in the path of travel. Unfortunately sometimes people were in the path of travel of these explosive occurrences. As these springs failed as an attempted safeguard some manufacturers devised a "caging" system for the springs. These cages were retrofitted onto the stretched springs in an attempt to capture the parts that would release if a failure occurred. While these caging devices were helpful they were not completely effective. Some of these spring devices are still in use today. Whenever this condition exists or the quality of garage components are questionable a qualified professional service technician should be consulted.
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.
