how to tension a roller shutter door spring

Roller shutters are popular for their durability, safety and ease of use. These doors rely on a coil spring mechanism to function properly, ensuring smooth operation and protection against unexpected breakdowns. However, over time, these springs can lose tension or break, affecting the overall function of the rolling door. In this blog, we will give you a step-by-step guide on how to effectively tension your rolling door springs.

Step One: Safety First
Prioritizing safety is paramount before attempting to tension a rolling door spring. Roller shutters are heavy and can be dangerous if not handled properly. So make sure you have the necessary safety equipment such as gloves and protective glasses.

Step 2: Identify the Spring System
There are two types of rolling door springs: torsion springs or extension springs. Torsion springs are usually located above the door and operate using torque, while extension springs are placed on the side of the door and work by extending and contracting. Determine what type of spring your rolling door has. Manufacturers often provide manuals or online resources to aid in this identification.

Step Three: Release the Stress
In order to effectively tension a rolling door spring, you must release any existing tension. This can be done by winding or unwinding the spring depending on the type. For torsion springs, insert the winding rod into one of the winding cone holes and apply force against the wind. For tension springs, carefully disconnect the spring from the pulley system.

Step Four: Adjust the Tension
To adjust the tension of the spring, it is usually recommended to seek professional help. Handling high tension springs can be dangerous and should not be attempted by anyone without the necessary expertise. Contact a trained technician who can efficiently tension the springs for you.

Step 5: Test and Observe
After the spring has been adjusted, the rolling door must be tested by opening and closing it several times. Pay close attention to any unusual noises or difficulties in operation. If you find any problem, please contact a professional to solve it immediately.

Step Six: Regular Maintenance
To ensure the longevity and optimum performance of your rolling door, regular maintenance is key. Lubricate all moving parts including springs, tracks and hinges. This will prevent rust, reduce friction and promote smoother operation.

Tensioning roller door springs requires careful attention to detail and knowledge to ensure safe and effective results. While this step-by-step guide can provide a general idea of ​​the process, it is critical to seek professional help when dealing with high-tension springs. Remember to prioritize safety and perform regular maintenance to extend the life of your roller shutter door. By following these guidelines, you can enjoy smooth-running doors and enhanced security for years to come.
