Currently, the so-called KDM type machines (combined road car), which are built on the basis of a bare truck chassis or are placed directly in a standard serial on-board or folding body, have become popular for road cleaning. The advantage of this technique is its versatility, which eliminates machine downtime during different seasons. All utility vehicles can be used as a means of extinguishing fires (for example, in forests).
general information
The main chassis for creating such machines were trucks of the Kama plant and the Likhachev plant. After the termination of the production of ZIL automobiles, the Tatar truck became the main domestic chassis for large utility vehicles.
KAMZ based KDM is created on the basis of a conventional cargo chassis with an elongated tipper body and is intended for cleaning and maintenance of the surface of paved roads at any time of the year. For this, the machine is equipped with all necessary equipment, the control of which is displayed on a separate remote control located in the driver's cab. The production of such plants is carried out at the enterprise PC “Yaroslavich”, Mtsensk and Arzamas plants “Kommash” and a number of other enterprises. In the manufacture of KDM based on KamAZ-65115, the main engine and transmission of the machine remain unchanged. The truck uses a 280-horsepower eight-cylinder diesel engine and manual transmission.
Yaroslavl option
The main component of the Yaroslavich PC development machine, model KDM-7615, is a mixture spreader, which is installed directly on the floor of a folding body. Since mixtures are made on the basis of various salts, the spreader housing must be resistant to their effects. Therefore, it is made of a sufficiently thick (about 3 mm) stainless steel sheet. The rise in price of construction is offset by the long life of the product. The internal volume of the hopper for the mixture on KDM based on KamAZ is about 8.3 cubic meters.
Optionally, the hopper can be made of ordinary steel and coated on top with a special polyurethane-based paint. This design is slightly inferior to the corrosion resistance described above, but costs significantly less. At the same time, the spreading unit is still made of stainless steel.
In the summer, the machine can be used for washing roads and cleaning them with special brushes, which are included in the equipment kit. The water supply is stored in removable plastic tanks and amounts to 10,000 liters. The maximum water supply distance is up to 18 meters.
Cars from Arzamas
This type of machine carries the designation KO-829B and is made on the chassis 65115. All equipment is attached to the car frame through a special subframe. It includes a tank for 14,000 liters of water, two additional plastic tanks of 6,000 liters each and a hopper for the mixture, containing up to 9.5 cubic meters of sand. Optionally, humidification tanks can be installed that hold 2080 liters of fluid. All important elements of the sand scatter system are made of stainless steel.
The maximum weight of the installation reaches 25 tons. Despite this, the dynamic and technical characteristics of KDM based on KamAZ-65115 remain at a level quite acceptable for the urban rhythm of movement. For example, the spread of the mixture reaches 10 meters, which is sufficient to handle most roads in one pass of the machine. At the same time, washing can be carried out at a distance of up to 20 meters from the machine, so that sidewalks and facade parts of buildings can be cleaned.
Mtsensky version of KDM
Such a machine carries the designation KO-823 and can be produced in several versions. Depending on the version, equipment for:
- Sand scattering.
- Watering the road.
- Cleaning the road surface with a plow and brush.
A feature of the KO-823 machine is a special brush unit drive that dampens vertical vibrations arising from roughnesses in the road surface.
