Many people are misled into thinking that the garage door opener is opening and closing your door. This really is not the case, the garage door opener is actually an operator, it operates the springs, which are the actual motors lifting your garage door. The operator attaches to and pulls on the midpoint of the door, and allows the springs to raise the door.
A torsion spring system consists of one or two tightly wound springs on a shaft with cable drums at both ends. Mounted on the header wall above the garage door. The springs consist of the steel wire with a stationary cone at one end and a winding cone at the other end. Cables run from brackets at the bottom of the door to the cable drums. When the door is raised, the springs unwind and the stored tension lifts the door by turning the shaft and cable drums, wrapping the cables around the grooves on the cable drums. When the door is lowered, the cables unwrap from the drums and the springs are rewound to full tension.
