Garage Door Pulley System

The garage door pulley system consists of various components working together to facilitate the movement of the garage door. Here are the key aspects of the garage door pulley system:

1. Cable Drum

The cable drum is responsible for winding and unwinding the cables that are attached to the garage door. It plays a vital role in ensuring the balanced movement of the door.

2. Extension Spring

The extension spring provides the necessary tension to counterbalance the weight of the garage door. It works in tandem with the pulley system to ensure smooth and controlled door movement.

3. Torsion Spring

The torsion spring is another type of spring commonly used in garage door systems. It utilizes torque to counterbalance the weight of the door and works in harmony with the pulley system.

4. Shaft and Bearings

The shaft and bearings provide support and allow for smooth rotation of the pulley system. These components are crucial for minimizing friction and ensuring efficient operation.

5. Garage Door Cable

The garage door cable connects the pulley system to the door itself. It is responsible for transmitting the force from the springs and pulleys to the door, enabling its movement.
