keeping the balance

When it comes to your truck roll-up doors, one of the biggest part of it's operation is based on how well your cables balance the door!

What most people don’t know is that cables are very rarely balanced properly and can lead to problems both immediately and over the long term which can cost you time, money, downtime and aggravation.

A poorly balanced door can affect your doors operation from cables hoping off and poor door sealing,  to spring and hinge wear, as well as putting your drive in danger.

Taking the few extra minutes to properly install cables will reduce these damaging effects and increase the operational quality of your overhead door.

When installing cables, McLaren Doors recommends following these simple steps to ensure your door is running properly:

Spring assemblies with independent cable drums

·       Once the door counterbalance spring has been set, roll the door open and closed 3 times.

·        Stand on the inside and have someone close the door.

·       With the door closed, inspect the bottom seal contact. The seal should be making even contact across the base plate.

·       If the seal is not making even contact, you can fix this by loosening the cable drum on the effected end of the door.

** Make sure it is done slowly as the weight of the door will correct quickly.

·        Once done, repeat these steps until the seal contact is uniform.

Spring assemblies with independent cable drums

·       Check the cable tension and make sure that both cables are under uniform tension and inspect the bottom seal contact. The seal should be making even contact across the base plate.

·       If the seal is not making even contact or one of the cables seems under tensioned, you can fix this by loosen the spring unit on the effected side until both the seal contact and the cable tension is even.

**Be careful when doing this as the spring is under high tension.

·       Once done, repeat these steps until the seal contact is uniform.
