Adjustment of Dorkhan roller gates. Doorhan gates: step-by-step instructions for self-installation

The most important factor Good and long-term operation of sectional garage doors depends on the tension in the cables. They are used to activate the work of the canvas, as well as to create balance of the entire structure.

A person who has this type of gate on his site should under no circumstances allow the cables to sag, because this is the main and main mistake when using them.

Due to such inattention, you may later encounter deformation of the guides and door leaf; the gate moves along the guides for opening and closing.

Adjusting sectional doors involves precisely adjusting the cables, but such a task cannot be called difficult. Each person can handle it with their own hands and without resorting to the services of specialists. The main thing is to understand how this is done.

Work algorithm

First of all, it is necessary to grab and strengthen the brackets at the bottom of the structure, after which a key is installed on each section of the gate. Next, the drum is fixed, and the set screw needs to be tightened.

At the second stage, the shaft is rotated until the traces of sagging completely disappear. To achieve the desired effect, a person will need to make one and a half to two turns of the springs. When the process is completed, each bolt is tightened on the tension lugs.

This allows the spring to be finally fixed, and the gate returns to the required state.

If the described algorithm and the adjustment made garage doors did not give the opportunity to get rid of the sagging, then it is necessary to use the principle of simultaneous rotation of the shafts.

Taking into account the fact that rotation can be done using the coupling design, initially each coupling bolt is loosened, and after that it is necessary to rotate the shaft from which the negative process is observed. The second shaft must be stationary, it is important to observe this.

Exhibiting structures with continuous shaft

If sectional garage doors are equipped with a continuous shaft, then the algorithm of work that will need to be performed will change slightly for the adjustment to be successful.

The working panel rises, then it must be fixed in this position. This will be necessary to loosen the tensioned cable a little.
The screw that secures the cable in the drum must be unscrewed.
Try to adjust the cable to the amount that you need to get rid of the slack. Try to reduce the size to the minimum mark.
On next stage The screw of the cable is tightened, with the help of which the fixation is carried out.
The panel returns to its original position, check whether you managed to get rid of the sagging and whether you managed to tension both cables equally.

If the adjustment of the garage door was successful, and the cable no longer sags with the help of springs, then you can safely leave the structure, because you managed to cope. If even a slight sagging is observed, then the algorithm indicated above must be repeated.

Each cable should be stretched evenly, so do not overdo it by tightening one of them.

If in the future you happen to encounter it again and need adjustment, you can safely use the methods described. This will ensure that your garage door is always in good working order.

Do not forget that even if there is no sagging, the tension of the cables will have to be checked from time to time.

You can adjust sectional garage doors yourself. To do this, you need to properly fix the cables and level the structure.

How to adjust garage doors with your own hands

If overhead garage doors are installed, you need to monitor the tension of the cables. Any adjustment can be done independently, without the involvement of professionals.

The cables fly off and get tangled, and as a result, the operation of sectional doors poses a threat to the entire structure.

What to pay attention to

The gate must be adjusted in the following situations:

You purchased them and are installing them yourself;
The installation specialists made serious mistakes.

When using sectional doors, you must pay attention to their correct operation. What we recommend you take a closer look at:

Geometry of lifting canvases. If there are distortions, this interferes with proper opening/closing. Most importantly, the risk of wear of basic structural parts increases, which leads to high costs.
State of the spring-inertia mechanism. Any distortion increases the load on the axles and rollers. These elements quickly fail. The cable may break and fly off the drum.

Check the quality of the components you will buy if replacement is necessary. Only certified spare parts from the gate manufacturer should be used.

Checking the cables

The main requirement proper operation The main difference between sectional garage doors is the position of the cables: it must be stable and tense, and they must be fixed evenly. They are used not only to move the working blade, but also to create a balanced state. Even minimal sagging causes deformation of the canvas and guides.

That is why the cables need to be adjusted on time. And you can deal with this yourself: you will need a minimum of working tools and not much time - unless repairs are required.

Adjusting garage doors with a split shaft

To adjust the design of sectional doors with a split shaft, you must perform the following steps:

The bottom brackets are taken. They must be securely fastened to the wall. Be sure to check the strength: they should withstand quite a lot of weight.
A sectional door key is installed on each section. This action must be approached as carefully as possible so as not to damage the structure.
Tighten the set screw and fix the drum.
Let's move on to getting rid of sagging. It is necessary to turn the shaft until it is completely eliminated. This is done slowly in order to have time to stop: then the cables will not be too tight. The adjustment must be correct, monitor the condition.
The springs are wound to completely eliminate sagging. For normal fixation of the cables, three turns should be enough.
The tips of the bolts are tightened, ensuring reliable fixation of the spring.

There is a possibility that the left and right cables will not be tensioned evenly. Mutual rotation of the shafts is possible. The design of the coupling allows this to be done. If one of the cables automatic gates still starts to sag, do the following:

The coupling coupling bolts are loosened.
The shaft on the side of which there is sagging is rotated.
The second shaft remains in its original position.
Getting rid of sagging.
Tighten the coupling bolts.

After this, the regulation of sectional doors can be considered complete.

Features of regulation of gates with a continuous shaft

Adjusting garage doors with a continuous shaft is easy; anyone can do it with their own hands. The process looks like this:

The working panel rises. In front of you will be a screw securing the cable. You need to lift the panel to loosen this cable.
The screw is unscrewed to allow the cable to be adjusted. The screw secures it in the drum.
The length of the cable is adjustable. Make it minimal. The main condition is complete elimination of sagging. But here you need to not overdo it so that the sectional door cable does not get torn off.
The cable is held in the required position. Now you need to tighten the screw that secures it.
The working panel is installed back. Now you need to check whether the sagging has been eliminated and whether the gate is evenly fixed. In case of discrepancy with the norm, it is necessary to repeat the procedure. It may not work out right away, so be patient.

After adjusting the gate operation with your own hands, do not forget to take preventive measures and monitor the cable tension during operation. This will reduce the risk of needing major repairs to your automatic gate.

Every good owner knows that any mechanism, even the most reliable one, can break down. And to prevent any unpleasant surprises, we recommend inspecting your garage door mechanism at least once a month for possible problems.
The most common problem with garage doors during their constant use is sagging of the cable, which is responsible for raising and lowering the garage door. This occurs due to improper installation of the springs on sectional doors.
First of all, we would like to draw your attention to the fact that adjusting or replacing the cable of sectional doors is unsafe, since the torsion springs are under high tension. Therefore, perform this work with great care and use only reliable and high-quality tools.
Here are the main stages of work:

Check the marking strip on the spring to ensure it looks like a straight strip.

Secure sectional doors so that they do not rise while repair work is being carried out.

Insert the tension rod into the hole where the spring ends and turn.

Perform the same operation with another rod, but pulling out the first one.

Secure the spring using a key.

Check the operation of sectional doors.

The installation of the torsion spring mechanism of Dorhan sectional doors is carried out according to a similar principle. If you still cannot adjust the tension of the sectional door cables, then our advice is to seek the services of qualified repairmen.

How to twist a spring on a torsion gate

Setting up torsion springs for sectional garage doors on our own it happens quite simply. Even a beginner in repairs can understand how to tension a torsion spring on a gate. The main thing is to comply with everything necessary measures precautions and use only high-quality tools.
If you are interested in how to tension and secure the cable on garage big gate, for example, manufactured by Dorhan, then you must understand that the entire torsion shaft is assembled in parts. So here's a basic plan on how to adjust a torsion gate mechanism:

Relieve the tension on the springs by lowering and fixing the structure.

Unscrew the screw, which will give the drum mechanism free movement.

You wind the cable.

Screw the screw into its original position.

Many inexperienced workers wonder: why do garage door cables fly out? The answer to this lies precisely in the uncoordinated operation of the entire mechanism and, in particular, the springs.

All renovation work on sectional doors they are carried out using the same method, but adjusting the cables of sectional doors with an electric drive still has some features. Since such structures, in addition to all components, have electrical components. Therefore, before proceeding with installation or repair, for your safety, you should disconnect the wires from the electric drive while performing work. Since accidentally touching the wires with a metal screwdriver can lead to electric shock. If you have sectional doors installed in your garage, then you will certainly be interested in the question of adjusting automatic garage doors yourself. After all, everyone knows what kind of work this is professional craftsmen They charge a hefty price, and every good owner wants to save money. Also, calling a specialist will waste your precious time, which is an unaffordable luxury these days.

The cables and their tension level are important in the entire design of such gates. The service life of your gate depends on them. They are intended to activate the workflow , and also to balance the balance. If you are the owner of just such a gate, then you should not allow the cables to sag.

Any owner who is concerned about the quality of his garage door mechanism can handle this type of work. All you need is to understand how to do it. To do this, we suggest that you watch the video presented at the end of the article.

Rules for adjusting overhead sectional doors

It is worth noting that when operating and repairing your garage door yourself, you should pay attention to the following rules:

Violation of the geometric component of your garage door, i.e. distortion of the canvas itself. If such a defect is not eliminated in a timely manner, it can lead to rapid wear of all structural parts.
Especially important has correctly adjusted balancing for the gate opening/closing mechanism. If errors were made during setup, this may lead to excessive load on the entire structure, and, consequently, the cable may break or other parts may quickly break.
And of course, you should always use only quality materials in installation and adjustment overhead gates. The reliability and service life of the entire structure will depend on this.

Adjusting the cables on a gate with one torsion bar - the task is not difficult and absolutely any owner can cope with it. But, if you are unable to adjust the tension of the sectional door cables, then we still recommend turning to professionals. Otherwise, poor gate repair can lead to further big problems and fatal errors.
