Different Types of Garage Door Springs
Extension Springs
They are widely used in residential applications because they are less costly to purchase, replace, and mount. Extension springs are located above the top tracks on both sides of the entrance. As the door rises and falls, this sort of spring expands and contracts, providing a counterweight and making the door easier to work. When the door is in motion, they stretch and contract with the help of cables and pulleys.
Inspecting a broken extension spring might show gaps in the coils. You should also pay attention to how your garage door is aligned. If one of the springs fails, the garage door will not open properly on that side and hang aslant.
Torsion Springs
In garage doors, the number of torsion springs can vary. It varies depending on the door’s size, weight, and strength. Torsion springs are mounted on the metal shaft immediately above the door opening. After the cable length and aluminum drums are set, the springs are tensioned, giving this spring its name.
The torsion spring can be broken if it has a split, crack, or separation. You can often tell if your torsion spring is broken by looking at it. For example, you could find a two-inch gap in the spring, indicating where it broke.
