A garage door needs springs to assist in its opening and closing mechanisms. Springs play a critical role in balancing the weight of the garage door, making it easier to lift manually or for the garage door opener to operate smoothly. There are typically two types of springs used in garage doors: extension springs and torsion springs.
Extension Springs: These springs are located parallel to the horizontal tracks on either side of the garage door. They stretch or extend when the door is in the closed position and store energy. When the garage door is opened, the extension springs release their stored energy, helping to lift the door. When the door is closed, the extension springs retract and return to their original position.
Torsion Springs: Torsion springs are mounted horizontally above the garage door opening, typically along the header. Instead of stretching, they twist or torque to store energy. When the garage door is closed, the torsion springs wind up and store energy. When you open the door, the springs unwind, releasing the stored energy, and helping to lift the door.
The use of springs in garage doors has several important benefits:
Counterbalance: Garage doors can be heavy, especially those made of materials like wood or steel. The springs counterbalance the weight of the door, reducing the effort required to open and close it manually or via the garage door opener.
Smoother Operation: Springs ensure that the garage door operates smoothly and doesn't slam shut or drop abruptly when closing.
Reduce Wear and Tear: By distributing the weight evenly, springs help prevent excessive wear and tear on the garage door opener and other components, prolonging their lifespan.
Safety: Properly functioning springs are crucial for the safe operation of the garage door. They help prevent accidents or injuries that could occur if the door were to fall unexpectedly due to its weight.
It's important to note that garage door springs are under significant tension, which means they can be dangerous if mishandled or improperly installed. If you suspect a problem with your garage door springs or need them replaced, it's best to hire a professional garage door technician who has the expertise and tools to safely handle the springs and ensure proper installation. Regular maintenance and inspections of the springs are also recommended to ensure they are in good working condition and to address any potential issues early on.
