Currently, no large-scale construction can be done without concrete pumps.
Thanks to concrete pumps, which ensure the delivery of concrete solution to places that are difficult to access or located at some distance from the equipped passage, it is possible to reduce the costs associated with carrying out concrete work by almost half.
Moreover, the use of concrete pumps allows builders to minimize concrete losses and maintain its quality, which always suffers when using other methods of laying it.
General description of concrete pumps
Concrete pumps are used to ensure the transportation of concrete mixture through pipes from to the place of its laying. Delivery of concrete by concrete pump has big number advantages, the main of which are:
- simplification common system necessary communications;
- the ability to combine horizontal and vertical transportation;
- eliminating the need manual labor during acceptance, movement and laying of concrete mixture;
- multiple increase in labor productivity;
- reduction in the total cost of work.
Concrete pump: design and principle of operation
In the classic version, the concrete pump combines the following elements:
- a chassis having a supporting frame on which all units and components of the concrete pump are mounted;
- drive in the form of a diesel or electric motor;
- hydraulic system, including a hydraulic pump station, distributor, hydraulic cylinders and cooling system;
- concrete transport system, consisting of a receiving hopper, an S-shaped valve, a gate, concrete transport cylinders and pistons of a cleaning system with a compressor and a water tank;
- control system in the form of a special electrical unit;
- Optionally, concrete pumps can have monitoring, alarm and emergency shutdown systems.
The principle of operation of a concrete pump is that the pump piston sucks liquid concrete from the receiving hopper and then pushes it into the concrete pipeline.
Types of concrete pumps, nuances of their design and operation
Concrete pumps are identified by several criteria. According to the operating mode with periodic supply of the mixture (piston) and continuous supply of the mixture (hose). They also differ in the type of drive: mechanical, hydraulic and pneumatic. Concrete conveying cylinders are divided by type into single-cylinder and double-cylinder. Concrete pumps are produced in several versions, such as:
- stationary;
- mobile;
- automobile;
The energy source of a concrete pump can be the vehicle's own diesel engine or an autonomous diesel engine, or one powered by electricity.
The main components of concrete pumps of all types are:
- hopper;
- drive unit;
- injection concrete pipeline;
- swing unit;
- auxiliary mechanisms.
As a rule, truck-mounted concrete pumps have a concrete-distributing boom-manipulator, but there are also concrete pumps without booms.
The pumping unit, which is one of the main units of both piston and rotary concrete pump, pumps the concrete mixture into the concrete pipeline, and the injection process is characterized by a cyclic nature.
Concrete pipes are assembled from individual welded or seamless steel pipes. Their diameter must be equal to the diameter of the piston and must remain unchanged over the entire length. Quick release locks are used to join pipes.
Most often currently used are two-cylinder concrete pumps that have a hydraulic drive and are called mini concrete pumps, due to their compactness. Characteristics Such devices are characterized by lower metal consumption and high performance indicators.
The presence of a pair of concrete transport cylinders, as well as the speed of devices that switch the direction of movement distribution valves and pistons, causes the mixture to be supplied to the concrete pipeline in the form of an almost continuous flow.
The productivity of currently produced hydraulic concrete pumps ranges from 15 to 120 m3/hour. They can supply the mixture over a distance of up to 250 m in the horizontal direction and up to 50 m in the vertical direction.
The pressure in each of the transport cylinders can range from 3 to 12 MPa, which depends on the operating conditions. Hydraulic concrete pumps, the brands and types of which are quite numerous, mainly differ only in the design of their distribution devices.
It should be noted that the clarity and reliability of operation switchgear largely determines the uninterrupted operation of the pump as a whole. That is why the search for the most advanced design of switchgears is constantly underway.
Concrete pump manufacturers
Concrete pump manufacturers various countries They currently produce a huge range of concreting equipment. The choice of these machines is so huge that it is almost impossible to talk about linking this production industry to a specific geographic region.
However, there are quite pronounced regional preferences in this area. Thus, in the Russian and Ukrainian markets, for example, concrete pumps from European, South Asian and North American manufacturers mainly predominate, while in the most North America preference is given to the Chinese concreting technique.
At the same time, on the Russian market everything is becoming more cars Chinese production, due to the following reasons:
- quite low, compared to Western European manufacturers, prices for supplied equipment;
- The models offered by Chinese manufacturers are similar to European models;
- Chinese concrete pumps are assembled mainly from components produced in Europe.
The most famous European manufacturers of concrete pumps are:
- German companies Reich Baumaschinen, ELBA-WERK, Schwing, Putzmeister;
- Italian companies MECBO, SERMAC, CIFA.
How to choose a concrete pump
In order to correctly select the optimal linear concrete pump for the conditions of a particular construction site, it is necessary to carefully study both the site parameters and the characteristics of the equipment.
First of all, it is necessary to evaluate the capabilities of the mechanism and correlate them with the distance over which it is planned to feed concrete mortar. This is required for both chassis-mounted concrete pumps and stationary models.
In the case when preference is given to truck-mounted concrete pumps, for example, a truck-mounted concrete pump with a distributing boom, a truck-mounted concrete pump or a truck-mounted concrete pump, then the determining factor in this case is the limitation of the boom. If the choice is made in favor of stationary models such as a concrete pump, then you should evaluate the power of its engine and then maximum distance, for which it is necessary to pump the concrete solution.
One should also take into account the following nuance: in the case of using a stationary concrete pump, there is no need to use a truck crane and a truck, and the small overall dimensions of the chassis make it possible to drive even in the city center and make the necessary maneuvers within the construction site.
Then you need to estimate the amount of work ahead. It may well turn out that a low-capacity concrete pump will be quite sufficient to meet the needs of a particular construction site.
Based on what is more profitable under existing conditions – electricity or diesel fuel, — you need to decide on the type of engine of the unit you are purchasing.
It is also worth thinking about the type of drive, which can be hydraulic or mechanical. For larger volumes of work, preference should be given to models with a hydraulic drive, as they have the highest productivity.
A properly selected concrete pump will ensure greater efficiency and speed of work, which will have a positive impact on the entire progress of construction.
Designed for supplying freshly prepared concrete mixture with a cone draft of 6...12 cm in horizontal and vertical directions to the place of laying during the construction of structures made of monolithic concrete and reinforced concrete. They are self-propelled mobile concrete transport vehicles, consisting of a basic chassis, a hydraulically driven concrete pump and an articulated boom with a concrete pipeline for distributing the concrete mixture in the area of the boom in all its spatial positions. Domestic concrete pumps are structurally similar and are equipped with two-cylinder hydraulic piston concrete pumps.
The concrete pump (Fig. 1) consists of two concrete transport cylinders 6, the pistons of which receive synchronous movement in mutually opposite directions from individual working hydraulic cylinders 10, alternately carrying out the suction stroke of the mixture from the receiving funnel 3 and the stroke of pumping it into the concrete pipe 1. The movement of the pistons is coordinated with the work rotary concrete distribution device 2, which is rotated to a certain angle using two hydraulic cylinders 12. When in one of the concrete transport cylinders the concrete mixture is sucked from the funnel, in the second the mixture is pumped into the concrete pipeline through the rotary pipe of the distribution device.
Rice. 1. Concrete pump
At the end of the injection stroke, the distribution device changes its position simultaneously with switching the stroke of the drive hydraulic cylinders using a servo system.
The receiving funnel is equipped in the upper part with a grid 4, in the lower part - with a paddle stimulator with a drive 11.
Concrete transport cylinders are placed in a housing 5, which has a reservoir 8 or flushing water and communicates with the rod cavities of the concrete transport cylinders. When replacing, the flushing water is drained through the drain hole, which is closed by a cover with a handle 7. The concrete pump is equipped with an electro-hydraulic control unit 9.
Hydraulic drive provides more uniform motion mixtures in the concrete pipeline, protects pump components from overloads and allows for wide adjustment operating pressure and machine performance. Double-piston concrete pumps with a hydraulic drive provide a volumetric flow control range of 5...65 m 3 /h with a maximum flow range of up to 400 m horizontally and up to 80 m vertically.

where A is area cross section piston, m; l - piston stroke length, m; n is the number of double strokes of the piston, s -1; k n - coefficient of filling of the concrete transport cylinder with the mixture (0.8...0.9).
The main parameter of truck-mounted concrete pumps is the volumetric flow (performance) in m 3 /h.
The concrete pump (Fig. 2) supplies ready-mixed concrete in horizontal and vertical directions to the placement site using a distribution boom 4 with a concrete pipeline 9 or an inventory concrete pipeline. The distribution boom consists of three articulated sections, the movement of which is controlled by vertical plane communicated by double-acting hydraulic cylinders 5, 7 and 11. The boom is mounted on a rotating column 3, resting on the frame 15 of the chassis 1 through a slewing support device 2, and is rotated 360° in plan by hydraulic rotating mechanism and has a radius of action of up to 19 m. A hydraulic tank 6 and a water tank 10 are also mounted on the chassis. An articulated sectional concrete pipe 9 attached to the boom ends with a flexible hose 3. The concrete mixture is supplied to the receiving funnel 14 of the concrete pump 8 from a concrete mixer truck or concrete truck. During operation, the truck-mounted concrete pump rests on hydraulic outriggers 16. Truck-mounted concrete pumps have a portable remote control remote control movements of the boom, consumption of concrete mixture and turning on and off the concrete pump, which allows the driver to be close to the place where the mixture is laid.

OJSC Tuymazinsky Concrete Truck Plant produces two models stationary concrete pumps:
concrete pump SB-207 with electro-hydraulic drive and power supply from 380 V network;
concrete pump SB-207A with a hydromechanical drive from an autonomous diesel engine D-144 with a power of 36 kW, which eliminates the need for power supply.
Concrete pumps are designed to receive freshly prepared concrete mixture with a standard cone slump of 6...12 cm from concrete mixer trucks or special loading devices and supply it through a concrete pipeline to the place of placement. They are used in the construction of buildings and structures made of monolithic concrete or reinforced concrete, and when performing finishing work.
The pumping units of the concrete pumps SB-207 and SB-207A are similar. Concrete pumps are mounted on a single-axle chassis and transported from site to site in a trailer truck. The chassis is equipped with four support posts, on which the concrete pumps rest during operation, and a towing device. High mobility and relatively small dimensions make it possible to effectively use concrete pumps in cramped conditions. The operation of concrete pumps is controlled from a stationary control panel.
Concrete pumps are operated at temperatures of - 5...+ 40°C.

To increase the functionality and efficiency of stationary concrete pumps, a circular concrete distributor BRK-10 is used, which is designed to receive freshly prepared concrete mixture from concrete pumps and place it in structures made of monolithic concrete and reinforced concrete. The concrete distributor is used most effectively when concreting large open areas: the foundations of structures ( zero cycle), road surfaces, airfields, hydraulic structures, ceilings, floors and roofs of buildings, etc.
The use of the BKR-10 concrete distributor makes it possible to realize the maximum horizontal range of the concrete pump and increase labor productivity by reducing the number of rearrangements.

Careful consideration of all available information before final selection of a particular option for this technique is very important. After all, the cost of equipment is very high and we are not even talking about buying it, but about renting it. In addition, a correctly selected version of the device will help to use it as efficiently as possible on the construction site and shorten the time required to complete all work related to it.
We study the main characteristics of concrete pumps used on construction sites
We can conditionally divide all existing characteristics of concrete pumps into several main categories dividing the equipment for certain types:
1. Drive.
truck-mounted concrete pump SANY SY5400THB-45 
concrete pump with folded boom
2. Pump design.
There are two main design options here: pistonless (rotary) and piston.
3. Concrete feeding device.
Based on the feeding principle the following options equipment: small-sized, stationary, linear and boom.
4. Method of transportation.
According to the method of movement, the following types of devices are distinguished: mounted on a tractor chassis, mounted on a conventional chassis vehicle, non-self-propelled trailers.
5. Pumping system.
IN in this case only two groups are defined: those equipped with either an S-shaped or C-shaped gate.

The principle of operation of the mechanism depends on what specific characteristics it has. Let's consider the most important points:
1. Hydraulic type.
A device with such a drive first transports the mixture into the hopper, then, by oscillating the piston, it tightens it (the process occurs after the discharge valve is closed) and pushes the mixture through the pipe (the process occurs after the said valve opens). The flow of the mixture flows evenly with a constant amount of dispensed solution.
2. Mechanical type.
The process is similar to that described above, but the piston stroke is not long, which is why the volume of supplied material is not the same. In addition, the speed of movement of the piston in the cylinder is not constant, which can lead to engine overheating.

types and operating principle of concrete pumps
3. Piston type.
The mixture is supplied by creating pressure from the movement of the piston in the hopper. The machines are equipped with automatic equipment, with which you can regulate the power of the supplied mixture flow. Pros: high productivity and the ability to deliver material over fairly large distances and heights.
4. Rotary type.
The mixture is supplied through the movement of a rotary rotor, which, drawing the material from the suction hose, squeezes it into the pressure hose. N can be used continuously over a long period of time. Pros: most often placed on small-sized devices (high maneuverability), as well as a very smooth and uniform supply of building material.

It will be useful to read our article: “Choosing the brand for the foundation depending on the type and size of the foundation of the building.”
Based on the characteristics of concrete pumps, we select a specific option
Having become familiar with the characteristics of concrete pumps, an experienced builder can already roughly determine which model he needs, but it would still be a good idea to point out what else you should pay attention to:
1. The volume of upcoming work and the size of future buildings.
A large amount of work requires renting a device capable of working for a long time and continuously, although this point also has its own nuances, which we will mention below. Regarding the size, large vehicles are almost never rented for driving private houses; they are used only in the construction of high-rise buildings.

table characteristics of concrete pumps SB-123, SB-165, SB-161, SB-126, BN-80-20
2. Accessibility of the site, in terms of free movement of vehicles.
A very important point in terms of choosing a mobile or stationary unit. The inability to drive close to an object using a self-propelled vehicle forces you to choose one that can be moved using lifting equipment.
3. Number of workers and time allotted for work.
The productivity of the unit must coincide as closely as possible with the ability of the workers to consume the delivered material. Otherwise they will either be idle free hands, or the device itself, the rental of which is more expensive than a less powerful option.
4. Dimensions and weight of the site.
The construction site itself must be able to withstand the load created by the weight of the vehicle and freely accommodate it.
By comparing all available initial data regarding the work with the existing parameters different types technology, you can choose the most effective and suitable option for you. The correctness of the decision determines whether you will save or overspend the available funds.
And how to make a concrete mixer with your own hands in our next article.
For the construction of a small facility, it is not always rational to use large-sized special equipment. Great solution The task at hand will be the use of mini concrete pump technology, which has similar parameters to the performance characteristics of large specialized equipment for construction. The small-sized concrete pump has proven itself in monolithic construction, where a prompt solution for pouring foundations and other load-bearing structures buildings.
Why choose mini equipment?
Buying a large stationary or mobile concrete pump does not always pay off. Expensive equipment can take months or years to pay for itself, while you need to solve production problems. A mini concrete pump can be rented, and if funds allow, purchased on lease or through another credit program. In the construction segment, there are universal tasks where it is necessary to fill structures without the use of large equipment, and at the same time it is irrational to use homemade concrete pumps. Low price special equipment with a full daily load will allow you to pay for yourself in about 6-8 months, and renting a mini concrete pump can “recoup” the investment even faster, but again, subject to a full daily load.
The market for small concrete pumps is quite extensive, there are Russian developments, but recently they can be seen on construction sites mini-equipment made in Japan, China, USA, South Korea, as well as a number of industrialized countries. For low-rise construction, where there is an average level of duty cycle, only a mini stationary concrete pump is the best solution organizing the work cycle process at the production site.
Technical characteristics of mini-special equipment
To properly organize the work cycle of a job where pouring concrete mixture is required, try renting a miniature concrete pump. Approximate technical characteristics of special equipment include:
- The maximum supply size of a hose with mortar is 150 meters.
- Maximum level supplying the solution to a height of 50 meters.
- Basic installation - electric or diesel engine general principle actions.
- Fully autonomous mode of movement.
Options for small concrete pumps
Before you learn correctly how to choose a concrete pump for construction work, we suggest you familiarize yourself with the groups of special equipment. There are two types of specialized equipment on the market, which are represented by the following categories.
- Piston type. The most popular version of the concrete pump group, which is used not only in the post-Soviet space, but also in highly developed countries. Thanks to the universal principle of the piston group, it is possible to organize a continuous cycle of supplying concrete mixture to the production site. The maximum level of performance of a concrete pump m 3 depends on the technological chain of organizing the supply of solution by piston group machines. Installation of piston category equipment occurs on a mobile chassis or on self-propelled equipment.
- Rotor system. This type of mini concrete pump is also used in a number of technological processes. Due to the presence of a sleeve with rollers, direct ejection of the solution in portioned parts is ensured. The delivery system bypasses the concrete pipe and goes directly into the hose. The productivity of such equipment is 2-3 times less than in a piston group, but is effective for highly specialized work of supplying concrete mixture to a construction site.
“The overall dimensions of a miniature concrete pump allow the installation of a bunker for receiving and processing concrete mixture.”
Along with this in technological process it is necessary to fulfill strict time requirements for processing the mixture, which should not exceed 20 minutes, otherwise this will lead to failure of the main process equipment. Exceeding the processing time of concrete can cause premature wear of special equipment, therefore, upon completion of work, it is recommended to thoroughly rinse all components of special equipment with a strong stream of water or other technological liquid intended for cleaning the concrete pump.
Features of the selection of small-sized concrete pumps
Considering the high popularity of purchasing and renting small-sized concrete pumps, we note the main technical and functional advantages.
- Mobility. The equipment is capable of maneuvering through difficult streets and roads of a large metropolis, where the quality of concrete comes first, and, therefore, prompt delivery of the concrete pump to the site is guaranteed by the acceptable dimensions of the special equipment.
- Compactness. Considering limited space production site, the mini concrete pump is the right decision for the construction process. For example, in order for Kamaz to be able to completely turn around, it is necessary to provide a free space of 10*12 meters; for a miniature concrete pump, this space is 5*6 meters, that is, if you are carrying out construction processes inside a workshop, then a small-sized concrete pump can easily turn around at your production site.
- Financial benefit. For large-sized equipment, it is necessary to attract a sufficient number of auxiliary forces, on average up to 5-6 people. Mini concrete pumping equipment requires the use of 1 driver and a maximum of 2 auxiliary workers. The financial component is quite impressive.
- Multifunctionality. Using a concrete pump is not only about supplying concrete mixture. Some models of special equipment are equipped with a mixer, which allows you to mix concrete if it is not possible to invest in the time frame for pouring the solution during the production cycle.
- Performance. Despite its very miniature size, the special equipment has sufficient productivity. The maximum volume of concrete processing, depending on the machine model, is 70-170 m 3 . The maximum height of hose supply and equipment operation is up to 25 meters; some models of special equipment will allow you to lift the solution to a height of 50 meters vertically and about 160 meters horizontally.
Popular brands of mini concrete pumps
Additional information about special equipment
Considering that many equipment manufacturers have provided additional machine control options, it is necessary to carefully study the possibilities of using auxiliary technological equipment for supplying concrete mixture. The main weight of the installation equipment is about 1 ton, so it is possible to transport special equipment by light-duty transport if there is no mobile-type mobile scheme. Upon completion of work with concrete, it is necessary to thoroughly wash all units and components of special equipment to prevent the formation of concrete build-up after the mass has hardened.
The concrete pump supplies ready-mixed concrete in horizontal and vertical directions to the placement site using a distribution boom 4 with a concrete pipeline 9 or an inventory concrete pipeline. The distribution boom consists of three articulated sections, the movement of which in the vertical plane is communicated by double-acting hydraulic cylinders 5, 7 and 11. The boom is mounted on a rotating column 3, resting on the frame 15 of the chassis 1 through a slewing ring 2, and rotates 360° in plan. a hydraulic rotating mechanism and has a radius of action of up to 19 m. A hydraulic tank 6 and a water tank 10 are also mounted on the chassis. The articulated sectional concrete pipeline 9, attached to the boom, ends with a flexible hose 3. The concrete mixture is supplied to the receiving funnel 14 of the concrete pump 8 from a concrete mixer truck or concrete truck. During operation, the truck-mounted concrete pump rests on remote hydraulic supports 16. Truck-mounted concrete pumps have a portable remote control for boom movements, concrete mix consumption and turning the concrete pump on and off, which allows the driver to be close to the place where the mixture is laid.
Operating principle of a concrete pump:
Range, height and depth of delivery From the tray of a concrete mixer (concrete mixer, mixer), concrete or solution is gradually unloaded into the receiving hopper of a concrete pump. The pumping unit begins pumping the mixture through a concrete boom directly to the unloading point up to 70 m in height and up to 200 m in length. Concrete and mortar can be supplied not only along the boom of a concrete pump, but also extended with additional concrete pipes, the so-called route.
The route is assembled on site from separate metal pipes, connected by special clamps. At the end of this route, a rubber trunk is put on to distribute the concrete over the formwork. The length of the trunk is 4 meters. You can use two trunks to increase the maneuverability of concreting.
If necessary, the route to the concrete pump can be connected without using a boom. Concrete pipes simply attach directly to pumping unit.
