Garage gate lifting adjustment. Installation of automation on sectional doors. We turn to the elimination of sagging, this technique also applies when the gate cables break

The car as a means of transportation has become an indispensable attribute for many residents of megacities. Its service life and appearance are greatly influenced by the operating and storage conditions. A garage equipped with a new generation of gates is a reliable marina for a vehicle.

Peculiarities

The products presented by Doorhan are in great demand. This company is engaged in the production and production of a wide range of gates. It is noteworthy that panels for such structures are produced directly in Russia, and are not imported from abroad.

Gates are installed by many car owners in their garages. Automatic adjustment, as well as setting and programming the key fob, allows you to freely enter the place of its storage without leaving the car.

A distinctive feature of the products of this company is reliability and a long period of operation. The degree of its protection against the penetration of strangers into the garage is very high. The purchase price is quite affordable.

Having the skills of installation and welding, you can install the gate yourself, without resorting to the help of specialists. It is necessary to follow the instructions step by step (it is necessarily included in the package of purchased products), tune in to scrupulous preparatory work.

Kinds

Doorhan manufactures and sells almost all types of garage doors:

• sectional;
• rolled (roller);
• lifting and turning;
• mechanical hinged and sliding (retractable).

Sectional doors for the garage are very practical. Their thermal insulation is quite large - no lower than that of a brick wall 50 cm thick, they are strong and durable.

This product is available in various designs. The Doorhan company provides for the presence of a built-in gate in the garage door.

Sectional doors are made from sandwich panels. The thickness of the canvas consists of several layers. The inner layer is filled with foam, which allows you to retain heat. Installation of such structures is possible in garages with small side walls.

Roll (roller) gates are a set of aluminum profiles, which are automatically rolled into a protective box. It is located at the very top. Due to the fact that the gates are placed vertically, their installation is possible on garages where the adjacent territory (entry point) is insignificant or there is a sidewalk nearby.

Your name lifting and turning the gate was obtained due to the fact that their canvas (a shield with a system of rollers and locks) moves in space from a vertical position to a horizontal one, thus forming an angle of 90 degrees. An electromechanical drive controls the motion process.

Sliding gates made of sandwich panels with a smooth or textured surface. The bearing beams of sliding gates are made of hot-rolled steel. All steel elements are covered with a thick layer of zinc. This provides corrosion protection.

The most common gates are swing. They open outward or inward. They have two wings, which are hinged with bearings on the sides of the opening. In order for the gate to open outward, it is necessary to have a territory in front of the house of 4-5 meters.

Doorhan has developed and introduced high-speed rolling shutters into production. A convenient moment with their intensive use is the speed of the workflow. The heat inside the room is retained due to the ability of the gate to quickly open and close. The heat loss is thus minimal. They are made from transparent polyester. This makes it possible to see the territory from the outside.

Training

Before purchasing doors manufactured by Doorhan, it is necessary to carry out their thorough analysis and preparatory work at the installation site.

Often, the garage area is not enough to install your favorite type of gate. It is necessary to correctly assess the situation (make calculations and measurements of all parameters, clarify how the structure will look like in the assembly).

At the beginning of work, you should measure the height of the ceiling (the frame is attached to it) in the garage, as well as the depth of the building. Then measure how wide the walls are. After you need to find out what is the distance between the top point of the garage opening and the roof (can be no more than 20 cm).

The opening is checked for defects. Cracks and irregularities should be eliminated by covering them with a solution, and then leveling all the irregularities with plaster. This should be done on both sides of the opening - external and internal. The whole further complex of works will depend on the quality of the prepared foundation.

Before proceeding with the installation of the gate, you need to carefully check their complete set.

The kit includes the following mechanisms: sets of parts for fastening and guide profiles; torsion engine; sandwich panels.

You can independently install the purchased gate, pull the cables, program the automation if you have the following tools:

• tape measure and a set of screwdrivers;
• building level;
• drills with a set of drills and nozzles;
• riveting tool;
• hammer;
• wrenches;

• jigsaw;
• knife and pliers;
• grinding machine.
• marker
• fixtures for fastening profiles;
• screwdriver and bit to it;
• a set of wrenches;
• spring winding tool.

You must be dressed in overalls, protective gloves and goggles.

All installation, welding, and electrical connections are carried out only with serviceable power tools.

Mounting

The gate installation algorithm is clearly spelled out in the instructions of the company that produces them.

Installation of each type is carried out taking into account the individual design features.

Sectional garage doors are installed according to the following scheme:

• opening verticals are mounted;
• fastening of load-bearing panels is carried out;
• install balancing springs;
• connect automation;
• handles and bolts are attached (to the door leaf);
• adjust the tension of the lifting ropes.

After connecting the electric drive, the quality of the web movement is checked.

Let's take a closer look at the installation. At the very beginning, you will need to prepare and install the frame. When the gate is purchased, it must be unpacked and unfolded to check for completeness. Then vertical racks are attached to the opening and a mark (bait) is made on the place where they will be located.

Be sure to go beyond the edge of the garage opening the sides of the bottom of the canvas. In the case when the floor in the room is uneven, metal plates are placed under the structure. Panels are placed only horizontally. Vertical profiles are installed along the lower section and fixing points for racks are fixed. A distance of 2.5-3 cm from the end edge to the guide assembly must be maintained.

Then racks are attached on both sides of the opening. The horizontal rails are fixed with bolts and angled connecting plates. They are twisted, pressing tightly to the surface. This is how the frame is assembled. Upon completion of this operation, proceed to the assembly of the sections themselves.

Gate manufacturers have made the assembly process easier. It is not necessary to mark or drill holes for the mounting panels, since they are already there. They put side supports, hinges and corner brackets (in the bottom panel). The structure is placed on the bottom panel, which must be adjusted horizontally, and fixed with self-tapping screws.

The next section is taken. On it you need to fix the side holders and connect with the internal loops. Side supports are placed in previously made holes. After that, the roller bearings, holders and corner brackets are fixed on the top panel. All elements are very tightly fastened to avoid breakage of structures and their loosening. The holes in the section should line up with the holes at the bottom of the hinges.

The panels are inserted into the opening one after another. Installation starts from the bottom section; it is fixed in the guides by the sides. The panel itself should go beyond the sides of the gate opening with its side edges in the same way. Rollers are placed on the corner brackets in the roller holders.

Separately, fixing profiles are assembled in the room and set in place in a vertical position. Racks are attached to the side of the opening. After a special plate, all horizontal and vertical guides are fastened. A framework is formed. The panel is periodically checked with a level so that it is placed strictly horizontally.

After attaching the lower section, the middle section is attached, then the upper one. All of them are interconnected by screwing loops. At the same time, the correct operation of the upper rollers is regulated, the canvas at the top should fit as closely as possible to the lintel.

The next step is to fix the support riser to the assembled gate with self-tapping screws.

On both sides of the section there are places for fastening the cable, which is fixed in them. In the future, it is used to operate the torsion mechanism. In the process of work, you need to install the rollers in the places intended for them. After the assembly of the shaft and drum is done. The drum is mounted on the shaft, a torsion mechanism (springs) is also placed there.

Next up is the top section. The shaft is fixed in a pre-prepared bearing. The free ends of the cables are fixed in the drum. The cable is pulled into a special channel, which is provided for by the design of the gate. The drum is attached with a special bushing.

The next stage of work involves adjusting the rear torsion springs. Buffers are installed in the middle of the opening, the cross member web is fixed to the ceiling beam using corners for fasteners. Further along the outside, a place is marked where the handle and valve will be attached. Fix them with a screwdriver.

A sleeve is put on the shaft, and a drive is placed on top of the guide and the entire structure is connected together. The bracket and traction are attached to the profile and everything is fastened with self-tapping screws.

The final installation operation is the installation of a guide profile, which must be above all ceiling profiles. Next to the drive is a beam with fasteners, on which the second end of the cable is ultimately fixed.

The tension of the cables is the final stage of the entire work process. After this stage, the gate system, mounted and installed by oneself, is checked for operability.

Automation of any structures is carried out using a drive and a control unit. The choice of drive depends on the frequency of their use and the weight of the leaves. The connected automation is controlled by a key fob, a programmed remote control, a button or a switch. Also, the structures can be equipped with an electric drive with a manual (rotary) lifting system.

Sectional doors are automated using chain and shaft drives.

To lift heavy sashes, use shaft. In the case when the gate opening is low, use chain. They regulate the stop and lifting of the canvas. Signal coded device, built-in receiver, radio button make these devices comfortable and very easy to use.

Sliding gates are equipped with hydraulic drives. In order for the sections to move smoothly, special rollers are used. The foundation in this case must be prepared in advance for roller carriages.

In swing gates for automation, electric drives are used (connected to each leaf). They have automation inside the gate, as they open inward or outward. What automation to put on their gates, each owner will decide for himself.

In the instruction manual, Doorhan door developers give advice on the correct use of their products:

Car owners of up-and-over doors are not recommended to put their cars close to the garage. The door leaf opening forward can damage the vehicle.

When choosing a design, you should pay attention to the appearance of the canvas. It will be the central component of the entire garage complex.

Pay attention to the garage walls. If they are made of ordinary brick, then they should not be strengthened. Walls made of foam blocks and other materials (inside hollow ones) are subject to strengthening. Their strength does not allow inserting the gate and using the torsion force. In this case, the frame is welded, which is inserted into the garage opening and fixed.

If your garage has sectional doors, then you will certainly be interested in the issue of adjusting automatic garage doors yourself. After all, everyone knows that professional craftsmen charge a rather high price for such work, and every good owner wants to save money. Also, calling a master will waste your precious time, which is a luxury these days.

Cables and the level of their tension are important in the entire design of such gates. It is on them that the life of your gate depends. 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 situations with sagging cables.

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

Rules for adjusting overhead sectional doors

It is worth noting that during the operation and repair of your garage door yourself, you should pay attention to the following rules:

• Violation of the geometric component of your garage doors, i.e. skew 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.
  
• Correctly adjusted balancing for the gate opening/closing mechanism is of particular importance. If errors were made during setup, this can lead to excessive load on the entire structure, and, therefore, the cable may break or other parts will quickly break
  
• And of course, you should always use only high-quality materials in the installation and adjustment of lifting gates. The reliability and service life of the entire structure will depend on this.

Cable adjustment on gates with one torsion bar - the task is simple and absolutely any owner can handle it. But, if you are unable to adjust the tension of the cables of the sectional doors, then we still advise you to turn to professionals. Otherwise, poor gate repairs can lead to even more problems and fatal errors.

Gate drive adjustment Dorkhan

Today, more and more of our customers opt for Doorhan gates. These are the most practical and reliable garage door models for your home.

But very often, after mounting the entire structure directly, you may have a question: how to adjust Doorhan electric gates? Adjusting sectional doors Dorhan (Doorhan) yourself is quite simple, you only need to follow our instructions.

If you are interested in how to tension a cable (chain) on a large garage door manufactured by Dorhan or another similar company, follow the instructions:

1. First of all, it is necessary to securely fasten the bottom brackets to the wall. The better and stronger you can fix them, the greater the load they can withstand.
2. Install a key for your gate section.
3. Fix the drum with the process of tightening the screw to install.
4. At this stage, you need to rotate the shaft until the sagging of the structure disappears. This work should be done slowly and unhurriedly so that you have a chance to stop at the right moment.
5. Screw the springs in two or three turns and no more.
6. Tighten the tips on the bolts, which will help to further fix the springs

Performing repairs according to this scenario, you will be able to maintain your garage door in the purchased form for many, many years. Nevertheless, it is worth checking the tension in the cables from time to time, as it can weaken without giving a visible effect. And, as you know, any breakdown, like a disease, is better to prevent than to cure.

Sectional door spring adjustment

In the process of adjusting the mechanism of lever gates, the most popular question among our customers is the issue of self-adjusting the springs of automatic gates.

Correct spring tension on sectional doors allows you to avoid sagging cables and, consequently, unplanned wear on the entire garage door mechanism. Such adjustment of the opening and closing of automatic sectional doors is quite simple by unscrewing and tightening the bolts.

Therefore, if you are interested in how to properly tighten the spring on a sectional door, for example, manufactured by Dorhan, or a similar design, then for this it is worth relieving the tension on the bolts and then turning the shaft from the side where the cable sag occurred. And then it is worth tightening the bolts back. This method is universal and works flawlessly.

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 the work of the garage door is carried out. 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 adjustment is not a difficult process, however, ignorant people may have a lot of questions about this.

Action algorithm

Cable adjustment is carried out in several stages. It is important to follow the step-by-step instructions so as not to miss anything and not damage the structural details.

1. At the bottom of the structure there are brackets that must be fixed at the initial stage of work. For each section of your gate, you need to install special dowels. After that, tighten the drum and set screw. This is the preparatory stage of the adjustment.
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 for the normal functioning of 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.

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 lot of 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

To carry out repairs, you will need a 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.
