A garage door is usually a huge steel door either attached to the garage or by some kind of electric motor to open it. Garage doors can be tall enough to accommodate cars and other larger vehicles. Also, small garage doors can be created in a single panel that tilts back and forward above the garage floor. This allows for more room inside the garage.
Most overhead garage doors have a swing out arm along one edge, which is then attached to a drum or rollers which move the door up and down on the tracks. Overhead doors can be designed with various different styles, from elaborate iron designs to sleek steel doors that offer little curb appeal. Many times, homeowners choose the style of their door based on the space they have available to them. Other times, they look at the design and size of their home and decide on the type of door best suited to their needs.
In the case of overhead doors, the system will consist of several cables. The cables are connected to a drum or roller that is attached to the ceiling joists above the garage door. Cables are suspended from these joists and rollers. These rollers are controlled by a motor which moves the cables along the tracks. As the motor turns these cables, the rollers move up or down the tracks thus opening or closing the door.
Usually there are three different types of springs in overhead garage doors. These include torsion springs, extension springs and extension ladders. All of these springs are important to the operation of the door but the quality and amount of workmanship that goes into the installation of these springs is often overlooked.
When the cables and rollers are set to function in conjunction with the motor, the entire assembly is often called a spring assembly. This is the part that is under the most stress and therefore the most important part to take care of. There are several things that you can do to maintain the spring assembly of your garage door. These things include lubricating the moving parts; applying weather seals to the hinges and rollers; and cleaning and painting the springs.
Garage doors that are made of steel are often supported by torsion springs. These springs are made of copper wire, which is twisted tightly together. On some cars, a third type of spring called a torsion spring can be used instead of the steel torsion springs. These are often more expensive than the steel torsion springs. Even though torsion springs cost more, they have been found to provide a better quality of lift and an increased lifetime of service than the steel springs.
