Sectional garage door adjustment. Do-it-yourself sectional door adjustment. Preparation for construction: drawings and diagrams

In order for a sectional garage door to serve for a long time, it is necessary that the support cables are always in a state of tension. These cables are simply necessary, since with their help all work is carried out. garage doors. Thanks to the supporting cables, the structure is in balance. If you have sectional garage doors installed, then you should carefully monitor the condition of the supporting cables, periodically inspect and adjust them. Sagging cables are one of the most common mistakes in the operation of such garage doors.

Actually, the adjustment of the garage door is the adjustment of the cables. If the cables are in order, then in most cases the sectional doors themselves will function normally. Their regulation is not complex process, however, ignorant people may have a lot of questions about this.

Action algorithm

Cable adjustment is carried out in several stages. Important to follow step by step instructions so as not to miss anything and not damage the details of the structure.

  1. At the bottom of the structure there are brackets that must be fixed to initial stage works. For each section of your gate, you need to install special dowels. After that, tighten the drum and set screw. it preparatory stage adjustments.
  2. At the second stage, it is necessary to turn the adjusting shaft until the cable is taut. As a rule, two turns are necessary to achieve the desired result. After you complete this process, you need to fasten all the bolts on the tension lugs. So you can fix the spring, and the slack in the cables will disappear.

It happens that the above process does not allow you to achieve normal functioning sectional garage doors. In this case, you can try to turn both shafts at the same time, which will achieve an even tension. Initially, you should dissolve both shafts and turn the one that gives the worst result. At this time, it is necessary to monitor the condition of the second shaft (it must be at rest), then both shafts are turned simultaneously and fixed.

Features of adjustment of structures with a continuous shaft

It happens that sectional garage doors come with a continuous shaft. In this case, it is necessary to apply a different algorithm of operation in order to adjust the gate.

  1. It is necessary to raise the working panel. Fix it in this position. This is necessary so that the support cable is loosened.
  2. Loosen the screw that holds the cable in the drum.
  3. Calculate the cable adjustment in such a way as to get rid of its slack. Try to make the size of the working part of the cable as small as possible.
  4. Tighten the cable fixing screw.
  5. Return the panel to its original state. Now you need to check if you got rid of the problem. If the result is negative, repeat the operation. Pay attention to whether both cables are equally tightened.

Try not to overdo it by pulling on one of the cables. Remember that both cables must be tensioned evenly. This is one of the keys to properly adjusting your garage door. If the gate is left in a state where one of the cables is pulled tighter, then this will inevitably lead to distortions and deformations.

In the future, you will probably have to deal with the adjustment of sectional garage doors again and again. You can use the instructions above again. So you can significantly extend the life of your garage sectional doors.

Remember that the tension of the cables must be constantly checked from time to time. If you notice that one of them gradually becomes unusable, strongly stretched and worn out, then it is necessary to replace it, and preferably both cables at once. This will increase the life of your sectional doors by at least one and a half times.

Sectional garage door service

Regardless of the type and specifics of use, garage doors need to be inspected and maintained from time to time. It is important to pay attention to the following factors:

  1. Corrosion. All iron components of your sectional garage doors (including supporting cables) are highly susceptible to corrosion due to moisture. It is important to clean up problem areas in a timely manner.
  2. Damage. During use, the gate may be damaged, which must be fixed by you and corrected in a timely manner.
  3. Pollution. Clean the gate from dirt in time. So you will not only improve the aesthetic qualities of your gate, but also extend their service life.

Follow these instructions and your sectional garage door will serve you for years to come.

This technique is for gates with a spring, torsion mechanism, which is located above the gate opening. For the correct and trouble-free operation of sectional doors, it is necessary to periodically carry out technical inspection and lubrication of moving parts.

With absence Maintenance gate, safety elements, such as a photocell, sometimes there are cases when the gate runs into mechanical obstacles when lowering. Mechanical obstacles are any objects accidentally forgotten in the gate opening. The consequence of a collision, as a special case, is a different tension of the cables.

Possible typical manifestations of misalignment of sectional doors with a manual chain drive or motor:

  1. the lift gate has stopped rising or falling;
  2. there is a bias on one of the sides;
  3. lifting is not carried out to the end;
  4. the descent of the canvas is not carried out to the end.

Typical design of a torsion shaft assembly. Single-shaft balancing system for garage and industrial doors. Split shaft.

For normal operation of sectional doors, the cables must be taut. Sagging of cables of sectional doors is not allowed.

As a result, the balancing cables of sectional doors fly off or get tangled.

Let's try to figure out how to fix this problem.

You - got confused, flew off, the cables on the gate and rollers broke off, the brackets are in place. This technique is also applicable when the cables are skewed.

First of all, at the beginning of the adjustment, we unblock the engine (if the control is automatic), if it is a chain, we will unblock the chain.

We produce a complete weakening of the traction spring.

The next step is spring tension.

We turn to the elimination of sagging, this technique also applies when the gate cables break.

With a weakened spring, we had the opportunity to remove the lower thimble of the cable. Next, unravel the cable. Having untangled the cable, we throw the cable into the groove of the drum, at least 1/4 of the drum. Next, we lay the cable behind the rollers. We fasten the cable loop to the thimble, depending on the design of your gate.

We turn to the tension of the traction spring and eliminate the slack in the cables.

Turn the shaft until the cable slack is removed. To ensure the tension of the cables, it is necessary to wind the springs by 1.5 - 2 turns and fix them in this position by tightening the bolts of the tension lugs.

Elimination of uneven tension of the left and right cables.

If one of the cables still sags, the sagging is eliminated due to the mutual rotation of the shafts, which is ensured by the design of the coupling (the presence of slotted holes for the coupling screws).

.

To do this, loosen the coupling bolts, turn the shaft, on the side of which there is sagging, while holding the other shaft in its original position.

After removing the slack in the cable, tighten the coupling bolts of the coupling.

The next step is to fully cock the springs in accordance with the recommendation. The number of turns must be indicated on the nameplate of the gate.

The torsion spring is responsible for balancing the door leaf.

It distributes all the weight evenly, thus making it easier to lift the gate. Acts as a counterweight. The force of the spring is directed upwards, and the mass of the gate is directed downwards. The ideal setting of the door leaf is set according to the method recommended by the manufacturer. Data on the number of turns of the spring tension is indicated in the product passport, on the nameplate of the door, available from the door supplier.

Check for correct spring tension.

The spring sags a little in the middle - this is its normal charged state. The number of marks on the skein must correspond to the number of revolutions indicated in the passport for the set.

Variants of the state of the torsion spring.

  • Curved upward;
  • wavy shape;
  • smooth;

The external signs of the spring indicate that it is overtightened.

If during the operation of the gate clicks or rattles are heard from the side of the spring, the torsion mechanism must be lubricated with liquid lubricant, if the sound does not stop, a specialist should be called. Check the condition of the spring before changing the season, and especially after severe frosts, the spring should sag a little in the middle - the main recommendation

After adjusting the springs, it is necessary to check the correct adjustment of the sectional door balancing mechanism.

To do this, raise and then lower the sectional door by hand. The applied force should be 10-20 kg. The movement of the gate must stop when the force stops.

How to eliminate the uneven tension of the left and right cables with a non-split shaft.

What does it mean not a split shaft - it does not have a coupling. The consequence of the lack of detail is that the tension of the cables is adjusted not from the top, but from the bottom. The coupling, as described above, eliminates the uneven sagging of the left and right cables.

Very often, after installation, sectional doors need additional adjustment. And more precisely, in the adjustment of the cables. Why is this needed? The fact is that unregulated gates deteriorate much faster and become unusable. Which in turn leads to unnecessary waste of money. So, first: What does adjusting a sectional door actually mean?

The main idea is to eliminate possible slack and ensure that the cables are tight enough, but, which is also very important, not overtightened.

I would like to immediately note that sectional doors are of two types:

  • with uncut;
  • with split shaft.

First, consider the installation algorithm according to the scheme: “sectional garage door adjustment”, if you have a gate with a split shaft.

Algorithm of actions when adjusting cables

  1. First of all, we take the bottom brackets and securely fasten them to the wall. It is very important to fasten them firmly, as they hold quite a lot of weight.
  2. Install the gate section key. This must be done very carefully so as not to damage other parts of the sectional door.
  3. After the key is installed, we fix the drum. This is done by tightening the set screw.
  4. The next step is to rotate the shaft until the slack disappears. This must be done slowly so that you can stop in time. Since there is a possibility that you will pull the cables. Of course, this will require effort, but the possibility still exists.
  5. To achieve a complete absence of sagging, it is necessary to wind the springs. Usually, in order for the cables to take their normal position, it is enough to make only two or three turns.
  6. After the springs are adjusted, the bolt tips are tightened, this must be done in order to additionally fix the springs.

Adjusting the spring of sectional doors eliminates sagging of the cables, and, accordingly, premature wear of the mechanism. But, unfortunately, it doesn't always work. If this is your case, then you need to adjust the cables in a different way.

Loosen the bolts, then turn the shaft from the side with which there is sagging, and the opposite side must be held in its original position. Then you need to re-tighten the bolts. This method is good because it always works, no matter if the Dorhan sectional doors are adjusted or the Alutech sectional doors are adjusted.

How is a sectional door with a continuous shaft adjusted?

This is a fairly simple process, so you can not paint a clear step-by-step solution to this problem. The gist is this:

  1. You must remove the work panel, after which you will see a screw that holds the slack cable.
  2. Next, you need to loosen it and adjust the length of the cable, since you have sag, you need to reduce it.
  3. After completing all these steps, you must screw the vit back, while holding the cable in the position of your choice, and install the work panel back.
  4. Once a sectional door has been assembled into a standard look, you need to make a thorough assessment of each of the cables. After all, it may be that at the time when you strengthened the screw, the cable weakened a little. In this case, you will have to repeat the entire procedure from the very beginning.

Using the above methods of adjusting sectional doors, you can always keep them in excellent condition, and only in this case they will serve you for many years without upsetting you with frequent breakdowns. But still, it is worth checking the tension of the cables from time to time, because over time it can weaken and then it will be necessary to tighten them again.

In order to effectively use sectional doors, it is necessary to ensure a stable tension of the cables. The cables are designed to move the working canvas, create balance. Make sure that the cables do not sag, even a little. Due to sagging, the door leaf can be deformed, as well as the guides. If sagging is found, the overhead sectional door needs to be adjusted.

The following signs indicate a skewed garage sectional door:

  1. The impossibility of raising / lowering the gate.
  2. Noticeable skew to one side.
  3. Inability to fully raise the gate.
  4. Inability to fully lower the gate.


Rules and technique for adjusting overhead sectional doors

When using and repairing a structure, you must remember the following:

  1. If the skewed gate is not repaired in time, the structural elements will undergo rapid wear. Will have to replace them with others.
  2. It is required to correctly adjust the balancing for the lifting mechanism. If the balancing is not carried out correctly, this can lead to an increased load on the gate. Possible breakage of the cable, breakage of other structural elements.
  3. When installing and repairing the structure, it is required to use only high-quality materials. The operating period of the gate depends on this.

Typically, the design includes 4-6 sections connected by hinged elements. When the gate is opened, the following happens:

  1. Sections move up, overlap one another.
  2. The movement of the sections is carried out thanks to the rotating drums and the cables wound around them. They are balanced by springs.
  3. Guides are located under the ceiling surface (longitudinally to the frame). They are designed to slide panels that are supported by roller elements.

Sectional doors have certain advantages:

  1. Saving a large number space, both in the garage and at the entrance to it.
  2. High thermal insulation performance of sections. The thermal conductivity index is 0.5 watts per square meter.
  3. High soundproof performance of sections (up to 29 decibels).
  4. The opening is well sealed.
  5. Sections can be installed in garages with different opening sizes.
  6. Increased fire protection.

For self-assembly of such gates, you will need the following tools:

  • pliers;
  • set of wrenches;
  • metalwork hammer;
  • rivet gun;
  • electric drill with a set of drilling tools;
  • measuring tape;
  • level;
  • gloves, goggles (to protect hands and eyes);
  • perforator;
  • construction knife;
  • marker.

Installation algorithm:

  1. Marking of fixing points of horizontals and verticals.
  2. Alignment and fixation of vertical elements.
  3. Installation of load-bearing elements with a lamella located at the bottom.
  4. Assembling the canvas with the section located at the bottom.
  5. Adjustment of the brackets located at the top.
  6. Fixing control nodes, bolts, handles.
  7. Spring installation.
  8. Summing up and connecting the electric drive.
  9. Installing limiters.
  10. Checking the move.

Required Tools and Consumables

Repair will require wrench, keys, fasteners (bolts, nuts). It is also necessary to prepare a collar. You can prepare an oily liquid to immediately lubricate the parts.

We turn to the elimination of sagging and breakage of cables with our own hands

Sectional doors are divided into 2 types: split and continuous. Each of these types of structures needs to be repaired in different ways.

Elimination of uneven tension of the left and right cables with a split shaft

The algorithm for adjusting structures with a split shaft is as follows:

  1. Fixing the bottom brackets.
  2. Mounting the key on the section.
  3. Fixing the drum by tightening the set screw.
  4. Shaft rotation. You need to turn it until the sagging is no longer noticeable. To tension the cables, the springs must be rotated 1.5-2 turns. After tightening the springs, tighten the tension lug bolts. This is necessary to securely fix the springs.

If the structure still sags, it is necessary to use the method of mutual rotation of the shafts. Due to the fact that the rotation is carried out by means of a coupling, loosen its tightening bolts. Then turn the shaft located on the sagging side. Make sure that the second shaft maintains its original position.

How to fix the uneven tension of the left and right cables with a continuous shaft

If the design is equipped with a continuous shaft, the adjustment sequence will be as follows:

  1. Raising the operating panel, fixing it in an elevated position. This is necessary to loosen the cable, which is stretched.
  2. Unscrewing the screw fixing the cable in the drum.
  3. Adjustment of length on the required size. If the cable sags, its working length must be reduced.
  4. Tightening the screw that secures the cable.
  5. Returning the panel to its place.
  6. Checking the state of the structure. Make sure it doesn't sag anymore.

If the repair was successful, nothing else sags, no additional steps will be required. Otherwise, perform the above steps again. Do not forget that the cables need to be tensioned in the same way.

Sectional door spring adjustment

To adjust the spring, do the following:

  1. Unscrew fasteners (bolts).
  2. Turn the spring one to three turns (the exact number of turns depends on the individual case).
  3. Tighten the bolt fastener.

This completes the spring adjustment.
