Garage door torsion springs are a critical component of overhead garage door systems. They play a key role in balancing the weight of the garage door and assisting in its smooth and controlled opening and closing. Here’s how garage door torsion springs work:
- Location: Torsion springs are typically installed horizontally above the garage door, parallel to the top of the door and perpendicular to the door tracks. They are mounted on a metal shaft that spans the width of the door.
- Counterbalance: Garage doors are heavy, and without the assistance of torsion springs, they would be difficult to lift manually. Torsion springs act as a counterbalance to the door’s weight. When the door is closed, the springs are under tension, storing potential energy.
- Opening the Door: When you activate your garage door opener or manually lift the door, cables attached to the bottom of the door pull on drums at the ends of the torsion shaft. As these cables wind around the drums, they unwind the torsion springs, releasing the stored energy.
- Balanced Movement: The release of stored energy in the torsion springs helps to lift the door with less force. This makes it easier to open and close the door, and it allows for smoother, controlled movement.
- Closing the Door: When you close the garage door, the torsion springs are wound up again, this time in the opposite direction. The tension in the springs helps to control the descent of the door, preventing it from slamming shut. This controlled descent enhances safety and reduces wear and tear on the door and opener.
- Maintenance: Over time, garage door torsion springs can weaken or break due to the stress of frequent use. Broken torsion springs are a common issue with garage doors and should be replaced promptly by a trained technician for safety reasons.
It’s important to note that adjusting or replacing garage door torsion springs can be dangerous and should only be done by experienced professionals who have the proper tools and knowledge. Attempting to work on these springs without the necessary expertise can result in serious injury or damage to the door. Regular maintenance and inspection of the springs are also recommended to ensure they are in good working condition.
