DIY garage door up. Do-it-yourself lifting gates. Installation of gates with counterweights

Making your own garage doors not only allows you to save significantly compared to purchasing and installing ready-made ones, but also brings moral satisfaction. It is much more pleasant for any owner to use something made with their own hands. It should be borne in mind that this structural element is not at all simple, and the importance of high-quality, reliable and beautiful garage doors is obvious.

Types of structures

Before you begin the manufacturing process, you need to decide on the type of structure. In recent years, overhead gates have become widespread. They come in two types:

1. Lifting sectional; (on the picture);
2. Lift-and-swivel; (Look at the photo).

Garage door installation technology

We propose to consider the technology of creating up-and-over gates, as the simplest and most inexpensive to manufacture. Having decided on the type of design, you can proceed directly to reviewing the instructions for making and installing overhead gates with your own hands.

Before starting installation work, it is necessary to complete the finishing of the adjacent ceiling and walls. Work on concreting floors may be carried out after installation of the gate.

Step-by-step instruction:

1. Assemble a frame from bars (one transverse, two longitudinal).
2. Fasten the beams together with plates.
3. The frame from below should be buried 2 centimeters into the floor.
4. Secure the box with pins in the gate opening.
5. Assemble the gate leaf from the selected materials.
6. Cover the canvas with sheet metal.
7. Make a mechanism support from an existing corner.
8. Make holes (d=10 mm) for attaching the bracket with the spring.
9. Make two holes (d=10 mm) in the slats located longitudinally.
10. Make a control plate.
11. Connect the spring and bracket with the adjusting plate.
12. Make a hinge unit from the corner.
13. Weld the frame and hinge assembly.
14. From two corners, make rails along which the canvas will move.
15. Weld a plate with holes and a guide.
16. Fasten the channel with a bolt to the beam on the ceiling.

At the first stage, the frame is assembled, then holes are drilled for the mounting brackets. After this, the box is installed and leveled, the holes between the profile and the wall are sealed with polyurethane foam. It is imperative to check with a level that the frame is installed correctly.

The next stage of work is attaching the guides to the ceiling. Then the canvas is assembled and inserted into the runners. Springs and levers are installed to ensure lifting and movement of the web. A profile for edging must be installed on all sides of the shield, and a limit strip is installed below to protect the gate stop from corrosion.

Necessary materials:

• Wood blocks measuring 120*80 (used for the box) and 100*100 millimeters (used in the manufacture of ceiling guides);
• Metal pins;
• Spring. Minimum diameter – 3 centimeters;
• Angle for frame and guide rails 3.5*3.5*0.4 and 4*4*0.4 millimeters, respectively;
• Bracket made of channel 8*4.3*0.5 centimeters;
• Rod (approximate diameter 0.8 centimeters) for making a voltage regulator.

Video instruction:

The most important points to pay attention to:

• The location of the guides must be strictly horizontal. This is necessary to avoid the web getting stuck while moving. The best option is to install hinge systems;
• It is necessary to correctly adjust the spring tension of the gate mechanism to ensure stability in any position of the leaf;
• For safe operation of the gate, it is recommended to install safety stoppers to secure the door leaf in one position or another.

The opening and closing of up-and-over gates is controlled either manually or using an electric drive, which is activated by a button or remote control. The last option is obviously more convenient.

Features of the lift-and-swivel design

The operating principle of this type of gate is that the door leaf, consisting of a single leaf, rises to the ceiling when opened. The movement of the sash is ensured by the action of a hinge-lever device.

Design advantages:

• Relatively high strength and resistance to breaking and possible penetration;
• Quiet operation;
• Possibility of making it yourself.

Self-production

• Structurally, the gate consists of three main elements:
• Box or frame;
• Movable sash;
• A device that closes and opens gates.

The box is the basis of the structure; it is made of beams, steel or wood. Guides are mounted in it along which the sash moves.

The lifting sash itself is made in the form of a solid canvas from different materials: a canvas made of boards, sheathed in metal, a sandwich panel, etc. Often used is the option of using a board made of boards, which is sheathed on the outside with galvanized iron and covered on the inside with polystyrene foam or some other heat-insulating material. No less popular is the design made of galvanized steel sheets, coated on both sides with protective compounds, and insulation located between the sheets. Expanded polystyrene or pressed foam is used as insulation. It is allowed to install a gate in the canvas or install anti-vandal roller shutters (Alutech) on the front side of the structure.

Another video about the features of making it yourself:

The gate opening mechanism is manufactured according to drawings and diagrams or purchased ready-made. The second option is quite acceptable, since there is a large supply of similar products on the market at very reasonable prices.

Lift-sectional gates

The main feature of overhead sectional doors is the presence of a door leaf made up of a number of approximately half-meter panels. In the process of opening, the canvas moves towards the ceiling, and when closing, it accordingly returns down to its original position. The panels are connected by hinges, the canvas moves along guide runners.

Panels are usually made of various materials: steel, plastic, and wood are used. For effective thermal insulation, the internal filling of the gate is made of polyurethane foam.

Design advantages:

• Simplicity of design;
• Operational safety;
• Relatively good strength.

Design disadvantages:

• Low resistance to burglary;
• Quite a high noise level;
• Difficulty in making it yourself.

It seems unrealistic to make such gates yourself, since almost all structural elements require factory production for reliable operation. Otherwise, you will have to sacrifice the performance characteristics of the design. The only possible saving option is to assemble the purchased ready-made kit yourself.

We install overhead garage doors with our own hands

Up-and-over gates are the most convenient, reliable, practical, but quite expensive type of enclosing structure for a garage. In the open position, they take a horizontal position and move forward slightly, forming a small canopy over the entrance.

Their pros and cons, as well as self-installation, will be discussed in this article.

Advantages and disadvantages of this type of gate

The up-and-over design has several clear advantages over other types of garage doors:

• durable solid fabric provides reliable protection against unauthorized entry and burglary;
• characterized by high resistance to corrosion and other negative effects of the external environment (subject to compliance with manufacturing technology and recommendations for the selection of materials);
• does not require space to open;
• when open, does not take up useful space;
• involves finishing with different facing materials, allows decoration with any inserts and panels;
• can be insulated with special polystyrene foam panels;
• can be opened manually or equipped with an automatic opening system;
• Suitable for installation in single and double garages.

The disadvantages of up-and-over gates are mainly associated with some limitations and features of the design itself, which are expressed in the following:

• it can only be installed in rectangular openings;
• when open, reduces the height of the opening (approximately 20 cm).
• the one-piece door leaf makes it impossible to repair individual sections - in case of damage, a complete replacement of the entire element is required;
• the gates are equipped with a spring mechanism, which is designed for a certain mass of the structure, therefore, when performing thermal insulation, the weight of the insulation should be taken into account: if the mass of the insulated gate increases significantly, it is necessary to install counterweights;
• There may be gaps between the leaf and the frame, which can be eliminated using a rubber seal, but it is recommended to install such gates only in unheated garages.

Gate operating principle

The design of up-and-over (panel) gates is characterized by a rather simple structure. It consists of frames, canvas and guides along which it rotates around its axis, moving from vertical to horizontal position and back.

The basis is a steel frame, which is fixed in the garage opening or behind it and is the leading part when the gate moves. For its manufacture, rectangular pipes are usually used.

When the gate is opened, a roller mechanism and lifting arms are activated, with the help of which the gate leaf moves along the guides and is then fixed under the garage ceiling. The lower part of the canvas rises up and forms a canopy over the garage opening. The compensation springs stretch when the gate is closed, but remain free when the gate is open.

Gate in open position

The opening mechanism for this type of gate is of two types:

1. Articulated lever- a simple, reliable and most popular mechanism that ensures simple movement of the shield and prevents it from blocking. Mandatory requirements: careful adjustment of spring tension and high precision installation of guides.
2. On counterweights– this mechanism consists of a cable attached to the lower corners of the frame and passing through the block, as well as a counterweight mounted on the opposite edge of the winch. This mechanism is recommended for use for massive gates with a lot of weight.

Control of panel garage doors can be manual or using an electric drive (usually with a remote control).

Selection of materials

Materials for up-and-over garage doors should be selected depending on the mechanism and leaf used. For the simplest gates that you can make with your own hands, you will need (all measurements are given in centimeters):

• wooden blocks: for a box with a section of 12x8, for a ceiling - 10x10;
• metal pins;
• corner: for frame - 3.5x3.5x0.4, for rails - 4x4x0.4 cm;
• channel bracket 8x4.3x0.5;
• spring with an internal diameter of 3 cm;
• metal rod with a cross-section of 0.8 (for the tension regulator);
• electric drive (if gate automation is provided);
• canvas.

As a canvas, you can use a board made of boards covered with metal, a solid canvas or a sandwich panel.

For self-made gates, the best option is a board panel covered with galvanized iron and coated with a protective compound. For thermal insulation, you can use polystyrene foam, polystyrene foam or insulation in mats, and to improve the appearance, you can line the finished gate with wooden panels or plastic.

Self-assembled gates

Necessary tools for work

To install an up-and-over garage door yourself, you will need a traditional set of tools:

• level;
• hammer;
• pencil;
• drill;
• spanners;
• screwdrivers;
• drill;
• Bulgarian;
• welding machine.

The first step in installing a gate is designing it. For this it is necessary measure the opening and draw up a sketch yourself or select a ready-made drawing.

Drawing of up and over gates

After this, materials and tools are purchased and the actual work of making the gate begins:

1. A box is assembled from bars, which are fastened together with squares or metal plates.
2. The box is fixed in the opening and secured with pins, the bottom is buried approximately 2 cm into the floor screed.
3. The gate leaf is assembled: the frame is sheathed with a shield and covered with sheet metal.
4. A mechanism support is made from a corner, two holes with a diameter of 1 cm are drilled in one shelf for fixing to the longitudinal posts, and three more are drilled in the other for fastening the spring bracket. To attach the channel bracket, used as a support for the spring, 3 holes are drilled in one of the shelves.
5. The bracket and the spring are connected using an adjusting plate made from a strip of iron. The outer coils of the spring are used as hooks, and a tension regulator made of a rod is attached to the bottom. On one side a ring is formed, on the other a thread is cut.
6. The hinge unit at the bottom is made from a corner with a hole (0.85 cm) and welded to the frame between the lower rib and the middle of the hole for the lifting mechanism lever at a distance of 12 cm.
7. A plate with a hole for the tension regulator is welded to the end of the lever.
8. Rails are made for the movement of the shield: 2 corners are made, and the edges of their shelves are welded so that the internal space between their tops is 5 cm.
9. One end of such a rail is welded to a plate with holes. There should be a gap of 8 cm between the center line of the guide and the lower edge of the crossbar. The channel pieces are welded to the other edges of the rails at a distance of 14-15 cm. The channel is attached to the ceiling beam with a bolt.

After assembly is completed, the structure is painted to give it an aesthetic appearance; it is recommended to paint hard-to-reach places before assembly.

• It is recommended to use welding to assemble parts, which will reduce the need for fastening and drilling holes;
• the height of the gate opening should not be less than 2.2 meters, and the distance from the top of the opening to the ceiling should be 0.35-0.5 meters;
• if the rise is low, the drum should be located at the rear;
• there should be a groove in the lower profile of the canvas into which the seal is installed;
• the weight of the canvas is a very important parameter, its optimal value is 100 kg;
• as a drive you can install a reversible self-locking winch (220 V, 350 W, traction force - 125 kg);
• To install automation, you can use a car alarm.

For ease of use, the canvas can be made with inserts made of translucent materials, which will increase the amount of light, and also be equipped with locking devices and security systems that protect against pinching or prevent break-ins.

Homemade up-and-over gates are the most economical opportunity to close a garage opening without limiting the functionality, ease of use and originality of their design.

The video shows a detailed story about making your own up-and-over garage doors:

When purchasing a car, owners first of all think about a cozy, warm, comfortable and spacious home for their steel friend. This individual space is called a garage. It can be attached to the house, or it can be a separate small building.

In any case, the garage simply must be equipped with a personal car entrance. Garage doors are the very first option in search queries for those who want to create this miracle of mechanics and technology with their own hands.

Types of structures

It would seem that nothing could be simpler: choose a standard gate for your opening - and not have any additional headaches. But folk craftsmen, proving to themselves and the world that they are no strangers, continue to look for new ways to save money and use their own creative powers and technical skills.

Among the wide variety of garage doors, there are basic designs that daily delight even the most demanding car owners with their functionality.

The simplest of them are classic swing models.. They usually consist of two leaves, in one of which the entrance door is installed. As a rule, swing gates are very massive and take up quite a lot of space. Since their opening requires a fairly large amplitude. They are installed on a metal frame, to which they are attached with durable canopies. Such gates require increased attention: monitoring the lubrication of the hinged mechanisms. Due to insufficient maintenance of swing gates, you can sometimes find them sagging.

Sectional doors for the garage are several metal movable panels connected to each other by hinges. The edges of each part are equipped with special rollers that move along special guides installed in the gate opening. They go under the ceiling, thanks to which the sectional doors smoothly go up, while saving space in the room.

There is a convenient variation of this type, when the gate slides to the side.

Folding garage structures also consist of vertical sections. But more often they are swing gates that fold like an accordion on the sides. They can be installed in an opening of any width (the number of sections - canvases - will depend on this).

They can be installed in such a way that they will fold both inward and outward, depending on the size of the room and the need to save it. The main load falls on the walls and ceiling, thus leaving the space free and unused.

One of the most common and easy to install types of garage doors are overhead structures. Like others, they can be automatic, but also have their own unique lever mechanism.

The mechanical model of overhead gates opens and closes with a slight movement of the hand., and by installing an additional bar with a motor, you can get excellent automatic gates with a remote control.

Materials

Any garage door is made from the following basic materials:

• metal (corrugated sheeting);
• tree;
• steel.

Structures made from corrugated sheets have a fairly long service life and have high strength. Treated with special anti-corrosion agents, such gates will be resistant to moisture and temperature changes. In addition, caring for metal structures is much easier than caring for any other materials.

Corrugated sheeting is very easy to cut and divided into the necessary sections/sections, removing additional weight load on the guides. However, when working on garage doors yourself, you should keep in mind that it is very easy to get deeply cut on the cut edges of the metal. Basic safety rules will protect you from getting an unpleasant injury.

Wooden garage doors are less in demand on the market, but also have their own functional value. Along with metal ones, they have a low price. Wood is always beautiful and natural. Perhaps, this is where all the advantages of the material end.

Wooden gates are fire hazardous, less durable and have very low strength. They are susceptible to rotting even after treatment with antiseptic and other impregnations.

Steel structures are somewhat more expensive than wooden and metal ones, but are just as durable and strong as the latter.

The main horse that most modern car enthusiasts and professionals bet on is sandwich panels. Practical and economical, such gates are good heat and sound insulators. They are very easy to install, insulate and wash. Excellent fire resistance properties will ensure the safety of your car in the garage with such doors.

Profiled sheets are also an excellent material for making garage doors. With such an entrance structure you are not afraid of weather conditions and mechanical damage. This is a very durable, beautiful and economical material.

Dimensions

Modern manufacturers of garage doors offer a huge number of dimensional varieties of their designs. Some can even make them to order. It won't be difficult for you to take the necessary measurements in your garage.

There is also the opportunity to make an independent calculation using preliminary drawings and diagrams. It is imperative to take into account the specifics of the room, the material from which your gate will be made, and the weather conditions that await them at different times of the year.

Professionals insist that overhead gates can only be installed in rectangular openings. The lifting mechanism also cannot be made differently than what is included in classic models.

A good option is to take ready-made standard drawings of overhead garage doors and substitute your own values ​​there so as not to make a mistake. In this case, the diagram must take into account not only the dimensions, but also the location of the entire structure as a whole. Particular attention should be paid to both the door leaf itself and the lifting mechanism.

The drawing details what measurements need to be taken and where.

The decryption is quite simple:

• H– the height of the opening into which the gate frame and the structure itself will be installed. It is very important to understand that the total height of the opening and the maximum height of the car that can enter the garage after installing the gate are two completely different things. This distance is measured in order to understand how much gap remains for lifting the gate to the ceiling.
• L– the lintel or depth of the garage and b1, b2 – the shoulder pads are necessarily located in the same plane, but they must have different sizes. In this case, L is always greater.
• B– the width of the opening should be measured with gaps of approximately 2 cm on each side.
• L– the depth of the garage is necessarily greater than the height of the entire gate structure, otherwise the door leaf simply will have nowhere to “go.”

How to do it?

It takes two to five days to make overhead gates yourself. Depending on the desired result.

For example, there are two types of lifting mechanisms:

• Levers + springs. Not the easiest, but the most common and safest way to raise and lower garage doors of light weight. During installation, special attention will have to be paid to fixing and adjusting the springs and high quality guides for the rollers.
• Counterweights. As a rule, it is used in the manufacture of homemade heavy-duty folding gates. The cable is stretched from the lower corners of the canvas, passes through a special block and is attached to counterweights located at the other end of the winch.

Determining the lifting mechanisms gives a clear picture of what tools and materials you may need during the production and installation process.

Let's consider the main stages of manufacturing overhead garage doors:

First stage– creating a layout and drawing of the future gate. A little has already been said about this. But when describing the production stages directly, you should start with this.

The second stage involves purchasing the necessary tools and materials for making gates:

• Rectangular pipe profiles 40*20 mm and 20*20 mm. It is very important that they have sufficiently dense walls: at least two millimeters. The former are well suited for making a canvas frame, and the latter - for longitudinal and transverse jumpers and guides.
• Gate leaf. Here the owner needs to decide for himself how he wants to see the entrance to his garage: profile sheet, sandwich panel, wood, metal.
• Wooden beam or metal corner. If you decide to use a lever-spring mechanism, these tools are ideal for securing it.
• Sliding rollers and the gate lifting mechanism itself.
• Insulation if you decide to make your garage warm even in the cold season.
• A set of complex tools: grinder, welding machine, screwdriver.
• Among the simple ones - only what can be found in the arsenal of any craftsman: a level, a screwdriver, a tape measure, a pencil, a hammer, wrenches.

When preparing the opening it should be taken into account that it must be in the same plane with the walls of the garage itself. This will improve functionality and simplify the operation of the structure.

Let's start leveling the walls, which can be adequately assessed using a construction water or infrared level. But also A prerequisite is the strength and horizontality of the floor covering.

So, all the preparatory measures have been completed, we proceed directly to the manufacture and assembly of overhead garage doors with our own hands. And this will be the third stage of work.

Let's make a frame. This is the main element that bears the greatest responsibility and the greatest burden. First, we assemble the box, which will be made of wooden beams or a metal corner, as indicated in the required materials. The main feature of the manufacture and installation of the frame box is that its lower part should extend 2 cm below the floor level. This is an additional means of fixing the structure.

It is important to remember that it cannot be adjusted using wooden wedges and foam. In order to “fit” the frame to the opening, it is necessary to use special metal inserts.

The next step is installing roller bearings. First you need to install the guides. They are sometimes also called roller rails. This point is important because the entire installation process must be accompanied by careful level measurements, otherwise the structure simply will not be able to function.

In the picture, the rails and their correct installation are highlighted in green so that everything works.

It's time to proceed directly to the gate leaf. Manufacturing options are simple and not very diverse.

There are three main types of installation of the gate shield itself:

• wooden frame made of beams, covered with sheets of metal;
• one-piece metal shield;
• metal profile base, on which a solid sheet is also attached.

This is the other side of the coin, that is, what will be located inside the garage. Of course, I also want to add insulation to our incredibly cold winters. As for external processing, everything here depends on your financial capabilities and aesthetic preferences.

The fourth stage in the manufacture of overhead gates is to install the wicket. If there is an urgent need for it, the production of the front door and its installation can be done with greater ease. Simple doors cut from gates and installed on hinges are suitable for this.. After all the main structural elements are ready, a full check of the mechanisms, tightness, level and functionality is carried out.

Many craftsmen in their video blogs talk about the possibility of automating overhead gates. The garage owner can also do this on his own. Here you cannot do without three main components: an electronic drive unit (the brain for automatically opening and closing the gate), a radio signal receiver and a remote control.

To install the first one, professionals advise using practically available means, such as a reverse winch or a power window mechanism.

Another important point is installing a lock on the gate. Since such a structure can often be opened with one slight movement of the hand, it will not be difficult for intruders to deal with both the gate and the contents of your garage.

Among the additional accessories that can be installed during the process of making a do-it-yourself overhead garage door are more decorative tips: installing windows that increase the amount of sunlight and save energy.

As can be seen from the step-by-step instructions for making lifting gates yourself, this process is quite labor-intensive and in some places even complicated. But thanks to the personal participation of the garage owner, it becomes noticeably more economical. For example, the average price of overhead gates from a domestic manufacturer can reach up to 70,000 rubles. When you do all the work yourself, you save about 60,000 rubles, taking into account the installation of options.

By following all the rules and steps in the manufacture of garage doors with a lifting mechanism, you will receive a universal and unique design that will protect your car at any time of the year.

Basic tips and recommendations for operating overhead garage doors come down to the care, adjustment and repair of all components in particular, and the system as a whole. For example, all rubber seals require additional periodic lubrication with silicone. This will help avoid cracking or freezing during the frosty season.

The lever system requires constant lubrication so that it does not rust, does not creak, and lasts as long as possible. Rollers, by the way, have the same hidden need. The tension of the springs needs to be constantly adjusted to ensure that the operation of overhead garage doors is as comfortable and durable as possible.

If the tension weakens, then the gate may simply not be opened. But if, on the contrary, the spring is overtightened, then the sash can be overturned and damage the leaf.

In case of mechanical damage to the door leaf, it is no longer possible to correct it. Since it is installed in one whole sheet, it will be necessary to replace the entire main door covering.

After all the basic manufacturing and installation work has been completed, you should worry about security systems. So, it is best to install feet on the rails so that the canvas does not come off the guides during operation.

One of the main tips from professionals and amateurs is timely diagnosis of the condition of the entire structure as a whole. As well as constant monitoring of the condition of its components.

Making your own overhead garage doors is a very complicated process. It requires constant monitoring, increased accuracy and responsibility. When starting work, you need to weigh the pros and cons of this process, and take on it with confidence. Taking into account all the nuances, tips and recommendations, any car owner will be able to produce exactly what he really wanted, but was scared to imagine. All people are the architects of their own happiness and their environment.

Nowadays, many types of garage doors have been created that are distinguished by their convenience and reliability. The most ergonomic and comfortable to use among the available options are considered to be traditional lifting (folding) structures, which, when opened, effectively disappear into the ceiling.

Types of lifting structures - which ones can you make yourself?

Overhead garage doors are most often manufactured in two main versions. They can be sectional or rotary. Gates of the first type are structures assembled from several plastic, wooden or steel panels up to half a meter high. The connection of individual elements into a common structure is carried out using hinges. Moving parts (couplings, rollers) are made of plastic or metal. But gate guides are always made of stainless steel. The inside of lift-and-turn structures is insulated with polyurethane foam. This ensures high-quality thermal insulation of the garage.

Pivot garage doors are characterized by decent strength characteristics, simplicity and safety of operation. The disadvantage of these designs is that it is almost impossible to make them yourself. If you plan to equip your motorhome with such gates, you will have to purchase them as a set of elements in a specialized store. You can install the factory kit yourself, following the manufacturer's instructions.

You can make your own up and over gates. Their design, which we will discuss in detail in the next section, is simple and durable. The key advantage of such folding systems is the high level of protection for the garage. They cannot be hacked without noise. In addition, turning structures provide truly convenient exit. They also do not take up extra space in front of the garage, which is very important for many motorists.

Disadvantages of rotary systems:

• “eat up” about 25 cm of the opening height (only when they are in the open position);
• the need to use high-quality (and therefore expensive) materials;
• large mass of gates.

Another disadvantage of the rotary design is that if the damage is significant, it is impossible to repair the system. The gate will have to be completely dismantled and then reassembled.

Design and principle of operation of folding gates

Structurally, the described systems, which many garage owners make with their own hands, are made in the form of the most durable and reliable support frame and a canvas covering the entrance opening. A diagram of such structures is shown below.

Folding gates can theoretically be built without guides. But experts do not advise doing this, so as not to reduce the operational reliability of the structure. The door leaf is made in one piece. If you have extra wood on your farm, you can actually assemble the entrance panel from it. But it is better to make the canvas from profiled sheets. This material is relatively inexpensive. And the fabric made from it provides excellent optimal protection from strangers. If the motorhome is used year-round, the corrugated sheets must be insulated with polyurethane foam.

To make lifting the web easier, we recommend using special compensator springs. In general, the movement of the gate leaf is carried out by levers, springs and rollers (the so-called hinge-lever mechanism). The system drive can be mechanical or electrical. Mechanics are considered more reliable during long-term use. Electric drive is more capricious and more expensive. But on the other hand, it is much more convenient to use (the opening/closing of the structure is carried out by command from the remote control).

Folding systems function simply and clearly. When the gate is opened, its upper part is deflected and then moves towards the beam along bearings or rollers, where it is fixed in a horizontal position (parallel to the ceiling). This system does not require the installation of external hinges, which could be cut off by attackers with a grinder. This provides unique security for overhead gates.

In addition, the sash that closes the entrance to the garage is adjacent to the supporting frame from the inside. Therefore, it will be much more difficult for criminals to pull the gate using a cable connected to a tractor or other powerful vehicle.

First steps - a competent start to work

The garage doors are manufactured according to a strict algorithm. First of all, decide on the type of mechanism for closing/opening them. We have already talked about the hinge-lever system. It is considered the most convenient, especially if the structure is built with your own hands. The main thing here is to achieve strictly vertical installation of the guide elements.

In some cases (in particular when installing heavy and large gates), such a mechanism may not be able to cope with lifting the sash. Then you should pay attention to the lifting system, which includes a counterweight. When implementing it, a metal cable should be attached to the lower corners of the support frame and securely fixed, and run it in the direction of the pulley along the block. A weight is placed at the end of the cable. The mass of the latter is selected taking into account the weight of the structure. The mechanism with a counterweight is labor-intensive to install. Therefore, if the gate has a standard weight and standard dimensions, it is better to install a hinge-lever system.

Next, develop a design design. Measure the parameters of the caravan opening for your vehicle, look at the drawings available in the public domain. Use ready-made sketches or create your own project based on them. Below we provide a detailed drawing that will allow you to create lifts with minimal time.

Then stock up on metal pins and rods, strong pieces of wood, brackets, steel corners, rigid springs, and if you plan to finish the structure, also decorative elements. Now you can proceed directly to assembling the gate. More on this later.

Assembling a lifting and rotating structure - bringing the project to life

The gate frame is assembled from two vertical wooden blocks of the required dimensions and one transverse element. These parts are connected to each other by metal plates or corners (the second option is preferable). Then follow these instructions to log in:

1. 1. Deepen the lower part of the canvas into the floor base of the garage (into the concrete screed) by 2 cm, then secure the structure with pins in the opening.
2. 2. Assemble the frame and cover it with corrugated sheets.
3. 3. Make a support from the corner. Drill three holes in one shelf of the product (they will be used to mount the bracket), and in the other - one hole (for fastening to the racks).
4. 4. Using a channel bracket, make a spring support. Connect the spring and bracket with a steel plate. Bend the outermost coils of the spring (you should get some kind of hooks). Connect a metal rod to them, which will act as a tension controller.
5. 5. Make a hinged (bottom) corner. Drill an 8.5 mm hole in the corner and weld this product to the support frame. Then install the lever to lift the gate. Weld a steel plate to its end.
6. 6. Make a rail (connect the corners by welding), attach it to the previously prepared plate at one end. Weld a piece of channel to the second end, stepping back about 0.15 m from it. Connect the latter with a bolt to the beam on the ceiling.

Now you need to install the rubber edging on the structure. If desired, additionally stick on compensator pads. They will increase the stability of the folding structure. All you have to do is secure the canvas well in the box. The gate is ready! You can use them for 10–12 years without the need for any repair work.
