How Does an Overhead Door Work?

You may have heard of three basic ways to operate an overhead door. But do you know how they work? Keep reading for more information. These are the backbone of overhead doors, so understanding them is essential. Learn more about them in this article.

Extension spring system

Here are some of the most significant benefits between extension and torsion springs. An extension spring is generally cheaper than a torsion spring system. Choosing between torsion and extension springs depends on the conditions of the building.

The first step in extension spring replacement is to identify the exact length of the broken spring. If the spring is bent or damaged, it will affect approximately half the door’s weight. A measuring hook should be placed between the two ends of the broken spring to measure its size. Using a digital scale may not be accurate since it does not react to weight changes caused by the door binding in its tracks. Using an analog scale will help determine how much the spring weighs.

If you choose the longer-life spring, check if the cables are damaged. This type of spring will last three times as long as a standard spring. However, the spring may still break at some point, so it’s best to get a new set to avoid future hassles. To do this, simply go to the nearest hardware store. Then, depending on the height of the overhead door, you can choose a longer-life spring.

Safety cable system

Overhead doors can be made safer by installing a safety cable system. This device is typically suspended over the overhead door cable and contains a cable drum. When the door closes, a portion of the cable is disengaged from the drum and contacts the device’s monitoring arm. Depending on the size of the door, the device may be used with different-sized cable drums and is easy to install. It may be attached to an existing overhead door or can be installed on a new one.

In addition to replacing cables, proper maintenance of an overhead door can help prevent injuries. Routine inspections from professionals like Overhead Door – Puget Sound include checking the drum, cables, and tracks for debris. Routine maintenance should also include lubricating rollers and checking for auto-reverse functions. 

Another component of a safety cable system for the overhead door is the safety cable. These cables connect the overhead brake with the electric power switch and prevent the door from moving. Sometimes, a temporary restraint on an overhead door can cause the cable to become loose and cause the door to fall. This is dangerous not only for the door but also for the people working inside it. You may want to contact a professional in garage door repairs to do the job. Moreover, a Safety cable system is easy to install and can save you money and time.

Gliding roller system

A Gliding roller system for the overhead door can be locked from the inside or outside the building. These doors feature a streamlined profile with an aluminum bottom rail to help prevent intruder penetration and durable sealant. This system is easy to operate and offers reliable, low-noise opening and closing with minimal friction. The only maintenance required is the occasional cleaning of the guides and a simple wipe-down of the door’s surface.

Another benefit of the Gliding roller system is its automatic reverse mechanism. This safety device detects a current surge and reverses the door when it senses the force of a moving object. Infrared beams have the disadvantage of becoming misaligned, and they are not compliant in the UK. The Gliding roller system is also compatible with infrared beams, a safety device that can be added to your door.
