Manufacturer "Dorhan" is considered one of the leading developers of garage doors with automatic control. The main and most promising direction of its activity can be called sectional structures, which take up little space and are distinguished by high ergonomics in handling. Having the necessary set of tools on hand, it will be possible to implement the installation of the Dorkhan gate with your own hands without professional help. But to obtain a high-quality result at each stage of installation operations, you should follow the instructions and do not forget about the nuances of the workflow in terms of connecting electrical devices.
Installation site requirements - what to consider?
At the stage of preliminary calculation of the garage door installation scheme, it is necessary to evaluate what the specific design parameters will be. Of key importance arethe dimensions of the opening are not only its height and width, but also the characteristics of the lintel, if it is planned to install an electric drive. For example, a Dorkhan chain electric motor with a gearbox requires that the distance from the top of the opening to the ceiling surface is at least 150 mm. The depth of the garage is also taken into account. Dorkhan gate installation experts recommend that when calculating this parameter, at least 500 mm should be added to the height.
In addition to the size of the opening, attention is paid to the condition of its surfaces. They should be smooth and even. Deformations, breaks and all kinds of curvature are not allowed. For a floor surface, level differences should be no more than 1 cm along the entire length. Installation should only be done in a vacant garage.
Installation tools and accessories
The quality of installation and especially the convenience of the installation operations also depend on how complete the set of tools recommended for installing the gate structure will be. In the instructions for installing the Dorkhan gate with your own hands, it is advisable to have the following technical means and devices in service:
- Electric drill.
- Grinder.
- Riveting tool.
- Hammer.
- Pliers.
- Sets of screwdrivers and wrenches.
- Marking tools - tape measure, level, pencil.
- Step-ladder.
- Knife.
It will also not be superfluous to take care of your own safety and prepare goggles, gloves and a hard hat.
Setmounting parts and accessories
The set of the gate itself may be different depending on the specific model. The basic set for installing the Dorhan gate usually includes the following elements:
- Mounting plates with supporting profiles.
- Gate curtain.
- Guides and rollers.
- Torsion mechanism.
- Racks and poles.
- Platforms and supports.
- Mounting kits, including several groups of bushings, nuts, bolts, spacers, etc.
Mounting activities are recommended to be performed with a partner. On average, a team of 2-3 people completes the work within 4-5 hours.

Before starting work, check the completeness of the kit and the condition of the parts. Mounting using defective or unsuitable elements is not allowed. The same applies to electrical equipment. The integrity of the cable, plug, insulation and drive mechanism is checked. If the components and the working tool are in good condition, then you can proceed with the installation of the Dorkhan gate with your own hands. The step-by-step installation technique is as follows:
- Assembly of panels. Top, bottom and side profiles (usually made of aluminum) with rubber seals are mounted to the door leaf.
- Installation of guides. C-profiles are mounted on top and bottom, along which the rollers will move. fastenersis carried out to the walls, the floor base and the upper part of the opening using self-tapping screws or dowels, depending on the base material.
- Installing the support brackets. These are U-shaped corner elements, the presence of which is due to the need to increase the reliability of joints between profiles running from different sides.
- Installation of the torsion mechanism. The key part of the working mechanism, responsible for the movement and assembly of the lamellas of the canvas. This part is also mounted to the corner brackets in special grooves using a pair of bolts.
- The web is being assembled and integrated into prepared niches with further adjustment.
Instructions for installing sliding gates "Dorkhan"
Less technologically advanced design compared to sectional doors, although it also provides for the possibility of connecting an electric drive. The main feature of sliding gates in terms of installation can be called the need for a foundation foundation on which the entire structure will be based. If the same sectional doors are held by the top and side panels with a torsion mechanism, then in the retractable model, the entire load falls on the lower base. So, the step-by-step instructions for installing the Dorkhan gate with your own hands in this case looks like this:
- Device foundation pit. A hole is dug along the line of passage of the gate with a depth of 70-100 cm. Then it is lined with concrete slabs or poured with cement mortar along with the supporting pillars from the configurationgate.
- Assembling the canvas. In some modifications, the Dorkhan sliding gates do without a solid shield at all. But in any case, it will be necessary to assemble the power frame profiles, which ultimately form the frame. You should get a rectangular shape with diagonal stiffeners.
- Installation of guides and rollers. On the foundation base there is a platform with guides and running infrastructure for the rail. The gear rack will become an active link when controlling the mechanics through an electric drive. It is installed in a special profile cornice, which is attached to the platform at the place of pouring the foundation.
- Installing the frame. The frame structure with or without canvas is attached to the pillars and is embedded in the chassis by means of special brackets. A tight coupling of two profile groups with blocking components is made.
Motor installation
As part of the drive mechanism, Dorhan usually supplies photocells to register the fact of passing through the opening, the control unit and the signal lamp. Installation activities involve the implementation of two basic operations:
- Mechanical installation. Installation is carried out on a prepared base. If the Dorkhan gate was previously installed on the basis of sections, then the device is mounted in the lintel area. In the case of a retractable structure, the block is fixed to one of the side posts using bolts or anchors. In any case, it is important that the drive is at least 150 cm above theland.
- Electrical connection. Usually, a 230 V AC cable in a protective corrugation is supplied in the package. Its laying is carried out so that the wiring, in principle, could not fall into the movement zone of the gate. The mains connection is made separately for the photocell transmitter, reducer and lamp.
Gate setting
With regard to sectional structures, it is necessary to adjust the tension of the cables. This is done by twisting the nuts on the metal sleeve of the torsion mechanism. With a wrench, you need to adjust the force until the canvas comes into contact with the lining and the floor. Again, an important condition for the correct adjustment of the tension of the cables is the evenness of the floor base, which must be ensured even before the installation of the Dorhan sectional doors. You can also adjust the sliding gates of this company with your own hands. In this case, the extreme positions of the web should be adjusted. They are installed according to the following instructions:
- Gearbox is being unlocked. At this point, the door leaf should occupy the desired position in terms of setting.
- The upper cam on the drive shaft rises until the circuit breaker operates. The sash closes and the cam is secured with a screw.
- The gearbox is again unlocked, after which the canvas is closed, not reaching 20 cm before full travel. The cam turns again until the switch is activated.
Gate maintenance
The company "Dorkhan" notes the highthe degree of reliability of their products, therefore, additional efforts to maintain the gate's performance on the part of the user are minimized. Nevertheless, it is necessary to periodically clean the surfaces of the structure, check the condition of the protective and decorative coating, and adjust the functional organs. Also, at the stage of installing the Dorkhan garage door, it will not be superfluous to provide opportunities for future improvement of the design. For example, as part of the modernization, it is possible to supplement the gate with lighting devices, motion sensors, security equipment and other accessories associated with a home security system.
Conclusion
As high-tech mechanisms enter the design of garage doors, the methods of their installation become more complicated. Today, it is not enough to simply hang metal doors on the hinges and tie-ins of the locking mechanism. Even in the basic version, the installation of the Dorkhan gate is a multi-level and technically complex process in which every little thing is important. On the other hand, trying to make the tasks of end users easier, the manufacturer optimizes door sets as much as possible in terms of installation. Therefore, adhering to the instructions, even an inexperienced home master in installation operations will be able to provide his garage with Dorkhan brand gates without outside help.
