To avoid the headache of getting your overhead

by:Hongfa     2020-09-10

Garage doors come in two main categories, if you want an overhead one. There are simple one piece doors which slide down and up using a panel which has a lightweight and rigid structure along with a horizontal set of panels which have junctures using hinges and fold when they are slip open and on there is also another variety of doors which have a more operation than the single door one. Both the models need to be serviced from time to time.

The first step while inspecting the door is to check the hardware and the hinges, rollers and brackets. Confirm that the bolts be tightly in place around the screws. If you attempt to tighten a loose screw and find that it has stripped its threads, pull it out and replace it with a carriage bolt. To put the carriage bolt, make a hole in the door, put the bolt inside it from the outside and tighten it with a nut and washer from the inside.

The next step is inspecting the door rollers for proper functioning and this should be followed with the inspection of the alignment and condition of the spindles. If a roller is observed to be broken, it should be replaced. It is required to lubricate the spindles, the roller bearings and the pins in the door hinges at least once in six months.

All the overhead garage doors are held in place by a metal panel on their sides along which the slide up. The ceiling joists support the two tracks for the single piece overhead doors. Section doors similarly have overhead tracks on either side but as they bend into vertical tracks as they come down. Rollers, mounted in door brackets, travel in the tracks to keep the door on course.

The tracks shouldn't be dirty and the plumbing shouldn't be irregular, in addition, they should be level or slightly pitched inwards. To have a regular and smooth movement of the door the rollers should move properly and there shouldn't be any bends in the track. Debris or dirt may accumulate over the roller and jam it.

The plumbing of the vertical column should be proper and the horizontal members should be leveled. Ensure that the tracks are parallel and the distance between them is equal! In case the tracks are not parallel, a wrench should be used to loosen the holding tracks and then tightened back into place.

The brackets should be tightly put back in place after they have been adjusted. Wipe the tracks clean from the inside and then spray the top of the track with some silicone spray. Heavy duty springs are coupled to the door with braided cable. They assist the operator in lifting and closing the door.

If you have managed to attach the springs correctly, the tension will hold the weight of the door till a height of three feet from the ground. For the remainder of the height, the door rises automatically. To readjust the spring, it is important to make sure the lubrication of the other components is done properly.

The S hook at the end of the braided lift need to be repositioned for adjusting the tension spring. This hook, above the opening on either side the door, fits into one of a series of holes in an overhead bracket. The door needs to be lifted to a certain height and clamps or blocks can be used to keep it in placed. The movement of the hooks should be forward to make the cable taut but on both sides it should be the same so that it stays balanced.

The torsion springs have an internal ratchet mechanism which can be tightened using an iron bar. The spring is under a lot of tension and this is a very dangerous procedure which may sound simple. You are advised to let a professional handle this.
