Maintenance Tips for Commercial Overhead Doors

Posted Friday, March 4th, 2016

It is important for businesses to keep their operations running smoothly and even more importantly maintain a safe working environment for their employees. The team at Cressy Door and Fireplace recommends routine maintenance and inspection of your commercial overhead door.

Maintaining Commercial Overhead Doors

Warnings

Door springs, cables, brackets and other hardware attached to springs are under very high tension. If handled improperly, it can cause serious injury or death. Please only allow a qualified professional to adjust or repair the torsion springs.

Never remove, adjust or loosen the red headed fasteners on the bottom brackets of the door. These are connected to the spring by the lift cable and are under extreme tension.

Spring Inspection

  1. Visual Inspection

    Visually inspect the door springs, cables, rollers, pulleys and other hardware for signs of wear.

    Some things to look for include:

    • Fraying cables
    • Tearing or bent hinges
    • Loose bolts or screws
    • Excessive roller wear
    • Rusty, dry or broken springs
  2. Lubrication

    Lubricate all moving parts of the door including hinges, rollers and springs with a garage door lubricant.

  3. Operation

    Motor operated doors should be disengaged and operated manually to assure all door components are functioning properly.

    To operate your door, make sure your lock is disengaged and raise the door to the open position. To close the door, pull down on the rope, step on the step plate to ensure the door is completely closed, and engage the locking mechanism.

    You should be able to life the door smoothly with little resistance. It should stay open three to four feet above the floor. If not, it is out of adjustment.

  4. Opener Test

    Finally, re-engage the opener and test. Make sure safety eyes are functioning.
