Springs, Pulleys, Chains, And Power: Know Your Garage Door

Know Your Garage Door

Ever taken a moment to consider the mechanics behind your garage door? The complex interplay of springs, pulleys, and chains is what ensures its smooth functioning. Let’s explore the fascinating world of garage door mechanics.

The Magic Behind Springs

Springs play a pivotal role in the function of garage doors. They counterbalance the door’s weight, making lifting and lowering a breeze. There are two main types:

  • Torsion Springs: Found above the garage door, they wind and unwind to control the door.
  • Extension Springs: Positioned alongside the door, they expand and retract with its motion.

A malfunctioning spring can be a safety hazard. If your door isn’t opening properly, check if the springs are broken.

Pulleys: The Unseen Workers

Pulleys work with springs to make the lifting and lowering process seamless. They reduce the force needed, making manual doors easy to handle and ensuring automatic ones function efficiently.

Chains Drive the Movement

Chains are like the heart of the garage door system. A motor drives them, causing the door to move up or down. If they’re noisy or seem off-track, here’s how you can deal with it.

Power: The Brains of the Operation

Garage door openers, whether manual or automatic, need power. Automated ones come with motors that can be of various types, including chain, belt, or screw-driven. Choosing the right one is crucial. Need advice? Here’s a guide to make the right choice.
