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.

Price

Today it is easier to purchase used equipment; for a KamAZ 53229 mixer, the price varies from 900,000 to 960,000 rubles, depending on the condition, year of manufacture and mileage. A photo will help to visually determine the condition of construction equipment KamAZ 53229 mixer.

If you need more modest equipment, pay attention to the Kolokolchik concrete bucket and the SBR 150A concrete mixer.

The preparation of the concrete mixture can be carried out both at the construction site and on the road during transportation - while the car covers the distance to the object, all the ingredients are mixed in a rotating drum, which saves time for preparing the solution. Reviews will help you learn about the advantages and disadvantages of using KamAZ 53229 mixer equipment.

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.

Design and operating principle

The technological process for producing concrete can be carried out using gravity or forced methods.

Gravity method: a pear-shaped container constantly rotates, maintaining the mixture in a liquid state, prevents loss of homogeneity and separation of the material, protects from harmful weather and climatic factors and prevents losses.

To load and unload the solution, 2-way screw blades are located inside the drum, operating on the principle of an Archimedes screw. When the elements rotate in one direction, cement and water with different fillers or ready-mixed concrete move towards the center of the mixer; when the movement changes, the solution is pushed out.

The rotating mechanism moves the tray 180° horizontally and 60° vertically.

Using a hydromechanical transmission, the drum rotates smoothly. The operating pressure in the system is 20-22 MPa.

In the forced method, the drum does not move, only the internal blades rotate.

The automixer device looks like this:

• chassis;
• dosing and washing tank;
• mixing drum;
• loading hopper;
• unloading bunker;
• folding tray;
• swivel mechanism;
• special equipment controls;
• control and measuring instruments.

To conveniently supply concrete to the site, use:

• gutters;
• pipes, sleeves;
• pumps;
• conveyor belts with unloading up to 14 m.

The telescopic boom increases the solution supply by 60 m.

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.
