In a garage door system, extension springs are mounted on both sides of the door and are often connected to the door’s horizontal track. As the door opens, the springs extend, pulling the door up through a series of pulleys and cables. These springs are typically rated for a specific weight and cycle life (the number of times they can open and close without failing). Over time, extension springs can wear out or break, leading to difficulties in operating the garage door. Regular inspection and maintenance of these springs are crucial for maintaining door functionality and safety.
Extension springs are typically made from high-tensile steel.
They are measured by their length, diameter, and spring rate.
The lifespan of extension springs is typically counted in cycles.
Incorrect spring tension can lead to door misalignment or failure.
Regular maintenance of extension springs involves checking for wear and tear, ensuring proper tension, and lubricating the springs to prevent rust. It is vital to replace springs that show signs of fatigue or failure to avoid safety hazards.
Did you know that extension springs can stretch to over 50% of their original length during operation?
