TRUCK HINGE MAINTENANCE

HOW TO MAKE YOUR HINGES LAST LONGER

We have all seen those trucks driving down the road with rust stains bleeding down the door and destroying the paint or tarnishing the decals. It looks bad, and if they are rusting like that, it means they are about to start having door issues. That means costly repairs and truck down time. NOT IDEAL!

Unless you are going to use stainless hinges or use a MCLAREN DOORS hingeless door, the fact is they are going to rust! MCLAREN DOORS has launched its new external hinge door, we have been researching different ways to improve the longevity of your hinge. We have managed to break it down to 3 simple points that we now call “Hinge S.L.C.” and we would like to share them with you.

Your Hinge S.L.C. are:

  1. Straight – When hinges are installed even on a slight angle, it reduces the life of the hinge. You might not notice right away but there are tell tale signs. Grease splatter by a specific hinge or difficulty opening the door at certain points could indicate signs of friction caused by slanted hinges.
  2. Lubricate – Greasing hinges once a month can greatly reduce the hinge deterioration rate as well as keep the door operating smoothly which can help reduce driver fatigue. We recommend a white lithium grease as it has less tendency to attract dirt, which brings us to our next point.
  3. Clean – Road debris, salt and environmental pollutants acts like sand paper on your hinges, and cause rusting especially between the door panel and the hinge. A quick spray will help clear out the debris and keep the hinge rotating properly.

Although you can’t stop the inevitable march of rust, with these three simple steps you can save some money, reduce an injury or even just keep your moving billboard looking better longer!

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 driver 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.
