We understand the types of roller mechanisms, choose the web and give instructions for installing console and suspended gates with an electric drive.
Entrance gates on the rollers are much more convenient than traditional folded, and it is easier to automate them. We will tell about how to choose a mechanism, assemble and install a rollback gate with your own hands.

Installing an electric drive
Retractable gates do not break off by the wind, reliably locked up, while opening the passages between the houses do not interfere with the maneuvering of the car. At the same time, the drive for them is one and a half or two times cheaper than for swing, it rarely capricious (unlike the hinge and lever drive of the sash). However, not all the designs of the sliding gate are equally convenient and durable.
Types of roller mechanisms
The reliability of the operation of retracting designs largely depends on the type of roller mechanism, so to begin with the field of the web movement.
Mechanism on roller support
The mechanism is the easiest and most cheap and does not require the acquisition of special details. The rail can be made from the corner (setting it up and fixing with steel crutches or partially imagined into concrete), and the rollers acquire ordinary TV, with a rubber or plastic rim, in which it is not difficult to do the groove to hold the roller on the rail (sheller's rails instantly clogged with mud).
Alas, the system has large drawbacks. Such homemade skate gates are afraid of snow and ice, moreover, with the time, the rail begins to deform under the pressure of the car passing along it. We do not recommend using the mechanism of this type, even in a relatively soft climate of the Krasnodar Territory and Stavropol, the more it will not suit it for Moskva and St. Petersburg.
It will automate only a design with stable geometry, not subject to skew and seasonal rolls.
Mechanism on roller suspension
For him, it is better to purchase special components, such as "Roltek", but it is possible to do without them: the rail is not so hard to make a square cross section from the pipe, the longitudinal groove in it, and roller carriages or single rollers to buy on the construction market. The design is the same as the interroom sliding door: the rail is installed above the opening (it is attached to the jumper from a powerful steel profile, concrete or brick, which relies on the side pillars). Inside the rail, mounted rollers for retracting gates, equipped with height adjustable by the brackets, on which the canvas is suspended. One of the lateral racks is mounted a lower fork, warning swaying when moving; The opposite rack is equipped with P-shaped cattakers. The design is quite reliable, the rack to the effects of the atmosphere, easily automates, but limits the height of the proof: to enter the cargo transport, it will have to dismantle the jumper, which is not always simple, and sometimes almost impossible.
The mechanism for suspended gates is equipped with rolling bearings.
The carriage consists of a pair of rollers with a double rim and bracket to which the canvas is fixed.
Console mechanism (self-supporting gate)
The most common system today, necessarily requiring special components, which produce Roltek, Dorhan, Alutech, etc., the main parts of the console mechanism - the carrier beam (it serves as the lower support profile of the web) and the trolley; Auxiliary - upper guides and support rollers, end lifts and gear rails for connecting the electric drive. The estimated service life of such a mechanism is 10-17 years (or 15-25 thousand opening and closing cycles). DIY systems offered by large dealers allow you to collect a rollback gate with your own hands, a step-by-step instruction with the photo we will give in the article.

The size of the suspended or console mechanism is chosen based on the mass of the web and the width of the day. The simplest and inexpensive kits are designed for weight up to 250 kg (sometimes 350 kg) and a 3 m wide.
Materials for the web
As a rule, the canvas consists of a frame (frame) and trim. The exception is forged products, but they also have frame elements to which the elements of the mechanism and the electric drive are fixed. The service life and reliability of the design depend on the choice of materials and the quality of the assembly of the canvas is almost to the same extent as from the mechanism.Wood
The frame of the wooden canvase is usually collected from bars or boards (for example, a cross section of 100 × 38 mm), reinforce with cut off and cut with boards with a thickness of 22-25 mm, while the boards are allowed to be directed both vertically and horizontally. To reduce the deformation, when the wood moisturize between the boards you need to leave the gaps of 5-10 mm (depending on the width of the board) or use the installation of the "Christmas tree" or "chess". It also does not hinder the roof above the gate - the so-called overturn (it is easiest to arrange it when designing on the suspension, as the jumper between the columns can be the basis for rafting farms and doom). Wooden canvas perfectly fit into the appearance of a country house, but will require regular painting and periodic repairs.
Professor
Structural designs today are most popular, like metal fences. The frame is usually welded from metal (corner, square tube), and the professional flooring is fixed with roofing screws or bolts. The main advantages of the design are relatively low weight, the stability of geometry and durability (with high-quality zinc coating and painting). Frame details should be protected from corrosion by rust paints.
When assembling the canvas, you can combine the decide elements and solid.
The lattice canvas less susceptible to wind loads.
Saintwich panel
The shell of such panels is performed from fine steel or aluminum, and the filler serves foolerolyrethane. The frame is made from aluminum p-shaped profiles, fastening them with mortgage elements and screws.

The strapping is collected using mortgage corners.
The sandwich panels look gracefully, do not rust and isolate the street noise, which is useful if the road with a revolving movement passes by the site. In addition, when damaged, any of the panels can be replaced, to acquire a new web for this there is no need. The ends of the sandwich panels are required to be thoroughly sealed, since the polyurethane is able to absorb moisture and collapse under its impact.
The cloth from the fillenteed sandwich panels will cost no cheaper.
Instructions for mounting a suspended gate
Now let's tell you how to make a sliding gate on the suspension mechanism. First of all (at the stage of the construction of the fence), there are reliable side pillars made of steel, concrete, concrete blocks or bricks. They must be shrouded at least 1.2 m, but better - below the ground freezing point in this area. Then arrange a jumper, to which, with the help of M-shaped brackets, a strictly horizontally fasten the rail. Next, the carriages and additional elements (trappers, guide rollers) and regulate the system to achieve smooth stroke and accurate sash in the catches.
Console Gate Mounting Sequence
It is quite possible to mount console structures. Step-by-step instructions are attached to the set of details, but there are also additional practical nuances that need to be considered.
The foundation is reinforced by a frame from a rod with a diameter of at least 8 mm.

Guides and catchers are fixed to the post.
The carriages of the self-supporting design must be installed on a reinforced concrete foundation, the depth of the embezzlement of which should exceed the depth of the primer of the soil. Do not save, since when the base is disturbed, the design will fail (the sash will stop entering the trappers, the drive will experience elevated loads and can burn). On the most bunted swampy soils (clays with an admixture of il) at the bottom of the foundation it will be useful to arrange broadening. Another option is the semblance of a pile-painted construction, where only the "anchors" are laid on the depth of the freezing, which are linked to the fine-gulled randbalknka on the sandy pillow (the consumption of concrete and the volume of earthworks at the same time). Sand and cement ratio for concrete preparation - standard - 1/3 (if you use the grade 400 and higher cement), the aggregate is a crushed stone of the middle fraction (better than 5-20 mm).
In the foundation you need to mount mortgages for fastening carriages. Adjust the position of the horizontal cloth helps the washers and nuts under carriages.
Installation of a drive for a rollback gate with your own hands
Automatically open the entrance to the area will help the drive. It is possible to establish it with your own hands, but this is due to a certain risk, as most companies provide a warranty on the electric motor only when installing a specialist dealer company.
The automation kit includes the drive, remote control and security device (signal lamp, photocells).
By visiting the wizard, you need to prepare a connection point, and even better - lay an underground cable (the depth of the trench should be at least 0.7 m). Optimal selection - armored copper cable with a cross section 2 mm2. Such a section is quite enough to work the engine, as well as security systems and video surveillance consuming the mining of electricity. You can also apply the usual three-core insulated cable, but it should be placed in a protective steel corrugation.
Rake is fixed only by teeth down.
The electric motor is installed on the foundation next to the cart.
Like other street networks, the liner to the drive must be grounded and is protected by the Uzo and the circuit breaker (or a combined device).
