Garage Door Pulley System

The garage door pulley system consists of several components that work together to ensure the proper functioning of the garage door. Let’s look at each component in detail:

Pulley Wheels

The pulley wheels are the main component of the garage door pulley system. They are responsible for guiding and supporting the cables that lift and lower the garage door. High-quality pulley wheels reduce friction and enhance the overall efficiency of the system.

Spring System

The spring system assists in the lifting and balancing of the garage door. It consists of torsion springs or extension springs, depending on the type of garage door. The pulley system works in conjunction with the spring system to provide a smooth and controlled operation.


The cables are an integral part of the garage door pulley system. They are attached to the pulley wheels and connected to the bottom of the garage door. These cables ensure that the garage door moves up and down in a controlled manner.


Bearings are used to reduce friction and facilitate smooth movement in the pulley system. High-quality bearings ensure durability and minimize maintenance requirements.

Bracket and Shaft

The bracket and shaft provide the necessary support and stability for the pulley system. They are securely attached to the garage door frame and hold the pulley wheels in place.

Replacing Garage Door Pulleys

Over time, garage door pulleys may wear out and require replacement. Here are the steps to replace them:

  1. Disconnect the garage door from the opener system.
  2. Release tension from the springs using the appropriate tools.
  3. Remove the old pulleys by disconnecting them from the cables.
  4. Install the new pulleys and reconnect them to the cables.
  5. Re-tension the springs and ensure proper balance.
  6. Test the garage door to ensure smooth operation.

Choosing and Customizing Garage Door Pulleys

When selecting or customizing garage door pulleys for diving schools, several parameters and practical considerations should be taken into account:

  • Door Weight: Choose pulleys with a load capacity suitable for the weight of the garage door.
  • Material: Consider the material of the pulleys based on the environmental conditions of your diving school.
  • Size and Design: Ensure that the pulleys are compatible with the existing garage door system and properly fit the cables.
  • Friction Reduction: Look for pulleys with features such as ball bearings or low-friction coatings to enhance efficiency and minimize wear.
  • Customization: If necessary, consult with a professional to customize the pulleys to meet the specific requirements of your diving school.
