Concrete mixer on KAMAZ chassis

Concrete is by far the most popular building material. Often, due to the remoteness of concrete production plants from the object being concreted and the impossibility of producing solutions directly on the site, it is necessary to resort to transporting the concrete mixture.

To organize its delivery to consumers, as well as to prepare the solution on the way and at its destination, automobile concrete mixers are used. Let's look at what characteristics the equipment on the KAMAZ chassis has, its positive qualities and negative aspects, prices for new cars, and also how you can seriously save money by purchasing a KAMAZ concrete mixer truck: used or from storage.

Requirements for transporting concrete

Requirements for the transportation of concrete solutions are specified in GOST 7473-2010 “Concrete Mixtures”.

Concrete mix

What should be considered when transporting concrete mixtures:

• The solution must be moved in such a way that the possibility of its loss is excluded.
• The possibility of sediment entering the mixture should be eliminated.
• The transportation method must ensure that the mass remains homogeneous.
• The time planned for transportation should not exceed the period during which the properties of the mixture are preserved (mobility and brand strength).

Transporting concrete using truck mixers is an effective way. Even moving it over long distances, it is possible to ensure that the mixture does not separate. Conditions are created that protect the cargo from the effects of sunlight, rain and other atmospheric phenomena.

The use of concrete mixer trucks makes it possible to produce the solution on the way to the construction site. To do this, the required amount of dry components of the mixture and water (in a separate tank) are loaded into the drum.

When approaching the object (30...40 minutes before the finish), the dry ingredients are mixed with water, the concrete solution is ready for use.

Types of concrete mixer trucks

All concrete mixer trucks (ABC) are manufactured on the basis of trucks. General requirements for equipment are formalized in GOST 27339-2016 “Concrete mixer trucks”. To transport solutions, the vehicle is equipped with a mixing drum.

The volume of concrete drums varies from 3 to 15 m3. The inside of the container is equipped with blades for mixing the composition, loading and unloading it. Depending on the type of operation, the blades rotate in different directions.

Mixer blades

Mixers installed on truck chassis differ in the following ways:

1. Direction of solution unloading. It can be done forwards and backwards.

Rear concrete unloading

1. Engine type. The mixer operates from an autonomous engine or by taking power from a truck engine.
2. Drum drive. It can be mechanical (rarely used nowadays) or hydromechanical.

Most mixer models are equipped with special tray devices for unloading concrete in hard-to-reach places.

Unloading concrete mixture into a prepared trench

Concrete mixers can be installed on specialized chassis, as well as on semi-trailers, which must be aggregated with tractors.

The technical conditions for the production of ABS standardize the following indicators of this special equipment:

• overall dimensions and weight;
• drum volume (geometric and based on concrete solution output);
• mixer rotation speed;
• volume of the water tank heated by the exhaust gases of the chassis engine;
• mixer drive power;
• loading and unloading height, etc.

What should be ensured by the design of a concrete mixer:

• receiving ingredients for preparing concrete mixture:
• preparing the solution in proportions as required by the instructions and with the required characteristics and its transportation without loss of properties;
• unloading of the finished mixture, including batch and emergency;
• variable frequency of mixer operation;
• controllability and stability of a loaded vehicle must comply with the requirements of regulatory documents;
• possibility of washing the concrete mixer.

Electronic controls, water flow devices, water tanks of various sizes, etc. may also be provided. In the market of concrete mixer trucks, a significant share is occupied by equipment manufactured on the KAMAZ chassis. Let's consider the model range of such mixers and their technical characteristics.

ABS device

Mixer diagram.

All auto mixers are equipped with oblong shaped drums. This container is mounted on the car at an angle of 10/15°.

Machine design

• The uniformity and safety of the solution during its delivery is ensured by the rotation of the drum.
• There are spiral blades inside it.
• Rotating in one direction during loading and delivery, they drive the mixture deeper into the tank. When the blades are moved in a different direction (the “Archimedes screw” principle is applied), the concrete is unloaded.

Note! The design of the concrete mixer truck is such that the solution can be prepared in it. To do this, you need to load fillers, water and cement into the drum.

• When unloading, the solution is pushed out of the drum under pressure and flows down trays to the work site. There are two such devices: one is equipped with the mixer itself, the second is installed by workers at the construction site with their own hands.

If the vehicle is not an all-terrain vehicle, then the ABS often cannot approach the work site to the required distance. In this case, the trays cannot reach the unloading area. Then special devices are attached to the concrete mixer.

Solution supply

Mixer with extended tray.

The mixer can supply the solution to the construction site using the following devices:

• standard or extended tray for concrete;
• conveyor belt;
• pipes;
• concrete pump;
• PUMIK.

Extended trays are used when unloading factory solution for a length of up to 7 m. They are extended using hydraulics. The pipe can be connected to a standard ABS tray, 3 m long.

It can also extend the concrete delivery distance up to 7m.

• Conveyor belts look like a rubber track 0.4 m wide and 10/14 m long. They work on the conveyor principle.
• The instructions say that they are capable of delivering the mixture to a height of up to 4 m.
• Such a device can be rotated left/right at right angles.

The photo shows a diagram of how ABS works with a pump.

A concrete mixer truck with a concrete pump is equipped with a folding boom and can pump the solution horizontally and vertically. The length of the boom, depending on the mixer model, can reach 60 m. The length of concrete supply can be increased using additional hoses 5 m long. They can be installed up to 4 pieces. Unit productivity is up to 80 cubic meters per hour.

The conditions for successful operation of ABS with a pump are as follows.

• To install the device, you need a solid platform, based on the car depot model - from 9?12 m to 12?15 m.
• It is desirable that the construction site have water for technical flushing of the unit and a place for its drainage.
• You can interrupt the supply of the solution for no more than half an hour. At temperatures below -5 or above +25 degrees there should be no interruptions.
• The unit can supply concrete of a grade not lower than M-200 (class B-15), which has a plasticity of up to P-4.

PUMIK is a machine that combines a concrete mixer and a concrete pump. It can pump mixture to heights of up to 28 m, with a range of 24 m.

Note! To install the unit you do not need a spacious area. To operate the machine, you need dense soil and free space around it.

Automotive concrete mixers KAMAZ

KAMAZ PJSC is a major manufacturer of trucks. The first truck rolled off its assembly line back in 1976.

Currently, the company is trying to keep up with the times, improving its products taking into account environmental standards, ergonomics, and using components in designs developed by recognized luminaries of the automotive industry. A big event was the start of production of trucks with gas engines in Naberezhnye Chelny.

Currently, the concern produces about twenty ABS models, and additional opportunities opened up after joining the group.

What is typical for KAMAZ special equipment:

• Compared to foreign analogues - affordable price.
• Excellent performance characteristics, reliability, service life.
• Adaptability to difficult road and climatic conditions.
• The ability to carry out simple repairs with your own hands.
• Available spare parts and components.

Using this technique, you can easily deliver concrete mortar to a construction site, as well as prepare it directly on site and distribute it around the construction site. If this topic interests you, we suggest you watch the video in this article.

Two-axle ABS are currently not in great demand and the leading ones, KOMZ-Export, which produces products under the Tigarbo brand, including those producing concrete mixer trucks on the KAMAZ chassis, have refused to produce them.

Three-axis models are the most relevant now. They are equipped with mixers with a useful volume of up to 9 m3. And here, mixers installed on the KAMAZ chassis are popular due to the budget selling price, cheap spare parts, usually available, and the possibility of self-repair of equipment.

While in this segment it is still possible to compete with the products of Chinese concerns, in the four-axle sector this is becoming increasingly difficult. Let's look at the most popular models of concrete mixers on the KAMAZ chassis.

Concrete mixer truck 58148Y

"KAMAZ 58148Y" - concrete mixer truck on the KamAZ 6540 chassis

The concrete mixer is installed on a four-axle chassis. Belongs to the Euro-4 environmental class. This equipment is equipped with a large-capacity drum (up to 8 m3 of finished mixture) and is intended for transporting concrete mixtures to large construction sites. It is fully adapted to the road and climatic conditions of various regions of Russia. Maximum travel speed is 60 km/h.

The base cost of the model is within 4.5 million rubles. An analogue of this concrete mixer is ABS 9DA from KOMZ-Export CJSC, made on a KamAZ chassis.

What characteristics does this TIGARBO concrete mixer truck have:

• KAMAZ 6540 also acts as a chassis;
• the volume of concrete delivered by this mixer has been increased to 9 m3;
• The water tank capacity is 800 l;
• autonomous motor for the mixer;
• The total weight of the ABS reaches 32 tons.

This ABS is installed on a three-axle chassis and belongs to the second environmental class. A little obsolete, not the most powerful in terms of performance (the useful volume of the drum does not exceed 6 m3), but a reliable mixer. The average fuel consumption of a car, depending on the operating mode, varies between 28...31 l/100 km.

The cost of a used mixer is in the range of 850...950 thousand rubles.

Important! A good option for purchasing budget equipment is to purchase it from storage, through conversion. The cost of the models is not much higher than the price of used machines (and often lower), however, these copies have not been in operation and only require maintenance to start working.

Concrete mixer truck 58147A

On the KAMAZ 6520 chassis, concrete mixer truck 58149 W

The technical characteristics of the KAMAZ 6520 - 58149 W concrete mixer truck, in which the power take-off for the mixer is carried out from the chassis engine, make it possible to transport a large amount of concrete solution.

What is interesting about this concrete mixer truck mounted on a KAMAZ chassis: 9 cubic meters. concrete can be delivered to the site at a time, the capacity of the water tank is 800 liters, and the total curb weight of the vehicle reaches 33 tons. When equipped with a Cummins engine and a ZF gearbox, such a mixer will cost 5 million rubles.

After the release of Federal Law No. 248-FZ in the summer of 2015, which tightened the standards for permissible vehicle weight and axle loads, carriers have to adapt to new realities.

Most of the equipment is operated with some underload, permits for overweight transportation are issued, or transportation is carried out bypassing public roads. Otherwise, very decent sanctions are provided: up to three hundred...four hundred thousand rubles for legal entities.

In order to make life easier for builders and transporters, the Tuymazinsky Plant has launched the production of lightweight concrete mixers with loads of less than 8 tons per axle: ABS 58145Y on the KAMAZ-65115 chassis (6x4 wheel arrangement) and ABS 58147Y on the KAMAZ-6540 chassis (with wheel arrangement) formula 8x4).

This three-axle automixer with a gross weight of 22.2 tons is driven by the chassis engine. The engine of the new model is Cummins ISB6.7 300 (diesel, turbocharged, Euro-4 environmental class) with a power of 307 hp. The car is 2016. (without mileage) will cost 3.1 million rubles.

Types of concrete mixers

Models of auto mixers are distinguished by several parameters.

Machine classification

ABS with conveyor belt.

• Type of working motor. The engine can be stand-alone or mounted on a chassis. The first type makes it possible to mix concrete even if the vehicle itself breaks down. Based on this, experts consider an autonomous motor to be the most reliable. Engines mounted on the chassis are lighter and more environmentally friendly; they make little noise.
• Mixer tank drive. Previously, ABS was equipped with its mechanical type. Now modern technologies make it possible to install a hydraulic drive on the unit.
• The unloading method can be rear or front. The first method is more common, because it makes it possible to approach the unloading point closer and deliver concrete accurately. Front unloading gives the driver the opportunity to control the process directly from the vehicle’s cab.
• The drum size is one of the main characteristics of the machine. The smallest is a 2 m3 concrete mixer truck. The standard largest volume of the mixer is 12 cubic meters.

Machine characteristics

An example of ABS technical characteristics.

The technical characteristics of the concrete mixer truck take into account the following indicators.

• The maximum volume of solution that can be loaded into the drum.
• Maximum weight of concrete (with fully filled water tank).
• Weight of the equipped mixing device. The load on the rear and front axles or axles is also taken into account here.
• Total weight of the vehicle and all special devices.
• Water tank volume.

As already mentioned, the model line of mixers represents 10 types of ABS, equipped with 2/12 cubic meter drums. To order, you can purchase the largest concrete mixer truck, which is capable of transporting 15 cubic meters of solution at a time. However, the price of such a machine is quite high.

Note! Many modifications can be applied to standard models of auto-mixers. They may concern hydraulic transmission, installation of water tanks of different volumes, and mixing drums. Changes can improve ABS control, autonomous engine, and water supply.

The most common brands of mixers

Mixer based on KamAZ.

Mixing and additional equipment can be installed on the chassis of a Russian or foreign-made vehicle.

The highest quality and most popular domestic models of mixers are assembled on the basis of the following brands of machines:

Most often, ABS is assembled on the KamAZ/6520 chassis, since its technical characteristics are optimal for installing equipment.

The most popular models of foreign mixers:

• MAN;
• Ford;
• Volvo;
• Mercedes-Benz;
• Scania
• Iveco;
• Renault.
