The garage door is a relatively modern invention. Garage doors have to counterbalance the weight of the door to make it open and close properly. The weight of the garage door determines the spring force of the springs used in its design. Garage springs come in 1 ¾” and 2 ¼ “ inside diameters. Garage doors open manually or by an electric motor. You have a garage door opener button in the car while you back out. 

Garage doors are held together using springs. There are multiple kinds of garage door springs. The spring is what makes the door open and close. Spring weights are determined by the weight of the door since if the door is 100 pounds, then the spring has to pull against the weight of the door. This is because types of springs pull against the weight of the door, with either torque or special parts that assist in balancing the door. New types of overhead garage doors roll along a system of tracks guided by rollers that guide the door into place as part of it’s mechanics. 

Garage doors have to counterbalance, which means a weight balances another weight if the weight is identical just like the way a pulley works. A 400-pound garage door uses cables and pulleys. The door and the weight are collected. Springs stretch and bend depending on the weight supported on the pulley. A garage door connected by cables on each side has one balance point. The springs are wound enough to support the door, as the door has to be counterbalanced. Standard lift counterbalance systems are designed to pull a lot of force because the door has to rise along the horizontal tracks. 

A garage door has the springs unwinding as the door rises. Cable drums are tapered instead of flat while the door rises to make the springs unwind. The spring is designed so that the pull matches the door weight even as the door is completely open and supported.

Standard torsion springs such as the type you find in lumberyards or at garage door companies will not work because they are not gapped. 

Garage doors have changed because of the insulation used in making them. The motor is hooked up to a 120-volt outlet. The Drive track moves the door open or closed. The operator determines the height adjustment of the door if a door isn’t opening and closing quickly. The force of the door’s motion is harnessed if the door is grabbed while moving. The inverter and battery of the door use a DC current. The average garage door in the United States opens 1500 times a year, according to Popular Mechanics because of the morning commute for those who have to go to work.
