Automated installations for receiving and supplying concrete

Truck-mounted concrete pump - technical characteristics, types and technology of its use in monolithic construction - is the main topic of this publication. To reinforce the material and visualize this review, a video is provided in this article.

This equipment is designed to receive and transport concrete solutions to the installation site using a concrete distribution boom and a pipeline system.

Characteristics of a concrete pump

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:

Distance, height and depth of supply
From the concrete mixer tray (concrete mixer, mixer), concrete or solution is gradually unloaded into the receiving hopper of the 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 expanded 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 are simply connected directly to the pumping unit. Application in the construction of buildings and structures made of monolithic concrete and reinforced concrete, construction of bridges, tunnels, etc.

What types of concrete pump designs exist?

Depending on the type of drive, concrete pumps can be hydraulic or mechanical. According to the design, pistonless and piston ones are poured. Depending on the method of movement, concrete pumps are either stationary or mobile. Despite the apparent diversity, today two types of concrete pumps are used in construction: piston (with hydraulic drive) and rotary (with mechanical drive).

In a rotary unit, the mixture is supplied by rollers equipped with the rotor housing: during the process of rotation, they press on the supply hose and the concrete is thrown out from there. But it is very difficult to make such a concrete pump yourself, since the design of the rotary type is complex, so usually piston units are assembled with your own hands.

The piston installation includes three main parts:

• Piston – powers the cylinder
• Cylinder - the part responsible for taking the mixture from the hopper and pumping it
• Drive – usually choose hydraulic or electromechanical

Single-piston units are most often used, since double-piston units require a complex design. Operation of two-piston units is carried out thanks to an electric or diesel engine, which converts hydraulic energy into mechanical energy.

Truck-mounted concrete pumps - technical characteristics - Pump concrete

Thanks to their technical characteristics, truck-mounted concrete pumps are widely used in the construction of buildings and structures, especially in the early stages of project implementation. This technique allows for efficient transportation of concrete mixture to the placement site - quickly, in large quantities and to hard-to-reach areas.

The main technical characteristics of concrete pumps include the following parameters:

• performance,
• distributing boom length,
• chassis type

Let us examine these points in detail. As a result, you will know in which case you should choose a 40 m3/h truck-mounted concrete pump or a 60 m3/h truck-mounted concrete pump, 75/35, and how many people should operate the concrete pump truck.

Performance of special equipment: concrete pump - 40 m3/h

When considering truck-mounted concrete pumps and their technical characteristics, one of the main parameters of the models is the performance of the machine. This indicator is also called volumetric supply, and it determines the amount of concrete, calculated in cubic meters, supplied to a certain location per hour of work.

When determining the technical characteristics of concrete pumps, the maximum (and not the average!) technical performance of the machine, measured at the outlet of the concrete distributor, is indicated. In the vehicle parameters it can be written, for example, as a 40 m3/h concrete pump or a 60 cubic meter concrete pump. m/h.

This indicator is very important, since it allows, knowing the volume of concrete mixture that needs to be moved from a concrete truck to the site to be poured, to calculate the time of use of special equipment, and then the total rental price of a concrete pump.

Concrete Pump Trucks - Dispensing Boom Length

The second important indicator when indicating the technical characteristics of concrete pumps is the length of the dispensing boom. The named parameter represents the maximum height of concrete supply using a concrete distribution boom from ground level. The length of the arrow is calculated in this case in meters.

Regardless of whether you rent a 40 m3/h concrete pump or a 60 cubic m/h concrete pump, the length of its distribution boom may be different. In modern practice, its value ranges from 10 to 101 meters. But in general, usually, the more powerful the machine is in terms of performance, the longer its boom will be.

It should be taken into account that the technical characteristics of concrete pumps indicate the length of the boom, which corresponds to its vertical output (and even then, in reality, it needs to be reduced by 0.6-0.7 m). And the horizontal supply of concrete will be on average about 3-4 m less than its nominal length. All this is determined by various design features of special equipment.

The above two parameters are so important that you can often find a description of the machine under discussion, for example, as a 75/35 concrete pump. In decoding, this means that in front of you there is a concrete pump with the following technical characteristics: productivity - 75 m³/h and maximum mixture supply from ground level - 35 m.

Concrete pumps - chassis type

When analyzing truck-mounted concrete pumps with their technical characteristics, such an indicator as the type of chassis also plays an important role. We are talking about a chassis on which a concrete transport device is mounted. The mobility of this equipment is given by the chassis, which is the basis for vehicles of various brands - KamAZ, Mercedes-Benz, Hyundai, Daewoo and others.

The type of chassis affects the following operating parameters of the equipment:

• power,
• cross-country ability,
• maneuverability,
• site size,
• other.

Moreover, a distinction is made between high-, medium- and low-terrain chassis. And when renting concrete pumps, all this also needs to be taken into account.

We will also now tell you how many people should service the concrete pump. In principle, one person—an operator—is sufficient, since the operation of this special equipment is almost completely automated. But in certain conditions, two more people may be needed, one of whom will regulate the work with the concrete truck, and the other will be on the site when pouring concrete.

Problems that may arise when laying with concrete pumps

Although laying the mixture using concrete pumps is easier and faster than performing the same work without it, you need to take into account some features of using these mechanisms.

Let's list them:

1. The increased speed of laying the mixture can lead to the formation of cavities inside the monolith, especially if a fine mesh is used for reinforcement. Therefore, you need to ensure that the concrete is evenly distributed.
2. If compaction is carried out with surface rather than deep vibrators, then it is necessary not to get carried away with large volumes of the laid mixture. Be sure to compact each layer.
3. It is necessary to carefully fix the reinforcement cage; a powerful flow of mixture from the concrete pipeline can displace the reinforcement elements and embedded parts.

A strong flow of concrete can dislodge the reinforcement cage

1. When working with a high-capacity concrete pump, it is difficult for one or even two builders to hold the flexible end of the concrete pipeline. You should give preference to a boom or at least hang the pipes on a crane.
2. Plugs formed in the concrete pipeline can damage it and the pump mechanisms. If it begins to form, try reversing the pump (if possible) for a short time. Otherwise, disconnect the area and clean the pipes by hand.
3. In order not to contribute to the formation of traffic jams, do not take long breaks in work; during this time, some of the concrete may set. Make sure that all builders (sometimes it becomes necessary to leave, even for a short time) can be replaced immediately.
4. At the end of concreting (or changing), both the pump itself and the concrete pipeline pipes must be thoroughly washed.

KSR concrete pumps are in high demand on the international and Russian construction equipment market. The machines are manufactured in South Korea.

Highly productive, high-quality Korean-made equipment has won the trust of specialists and owners. This will be the subject of our consideration.

The material will help you learn about the characteristics of the machine, find out the opinions of the owners and compare the cost of some automobile concrete mobile pumps.

KCP concrete pump technical specifications

Speaking about the technical part of cars of this class, you need to pay attention to:

• to the feed height;
• speed of concrete delivery;
• and maneuverability.

DAC manufacturers have a lot of different equipment. Let's take as a basis the KSR 37RX170 concrete pump with a delivery height of 38 m mounted on a Hyundai chassis. The machine complies with Euro 4 standards.

Read the article for KamAZ 65117 owner reviews.

Concrete pump KCP characteristics of model 37RX170

First of all, the feed height. This model has a capacity of 36.8 meters. The delivery range extends to 32.2 meters. In front of the car, this process is possible at a distance of 29.8 meters. A video of the KCP concrete pump is posted at the end of the material.

As we can see, there are good concrete delivery rates. This technique can be used on medium-sized construction sites.

The front support distance for the 37RX170 is 6.18 m; the rear ones are located at 7.15 m; the installation weighs 20.5 tons. At the same time, the equipment is mobile and maneuverable. This is evidenced by the boom rotation angle of 370 degrees.

Sections can rotate at different angles. Here are the numbers: 94°/180°/240°/245°. It's worth paying attention to the performance mentioned earlier. The figures are 170 cubic meters. m per hour. Good speed performance. Fast delivery will shorten the entire construction process. See the photo of the KCP concrete pump at the end of the publication. Much in this technique depends on the correct and stable operation of hydraulics. The KSR 37RX170 model has a pump from Kawasaki - K3V180S. Hydraulic lubrication supply with manual control and control. In principle, there are no special differences in the CSR technique.

Drawings and diagram of KCP concrete pumps

The drawings of KCP concrete pumps are fundamental. They can be found on the Internet. When purchasing equipment, along with other mandatory documents and instructions, design drawings must be attached. You can order and buy a KCP concrete pump:

• with Z-shaped;
• R-shaped;
• or RZ-shaped assembly diagram of a retractable boom.

Cost of KCP concrete pump

Large and powerful equipment, especially one known throughout the world, is expensive. But this cannot stop those who need it. There are different prices, but they all start from RUB 1,000,000.00.

KCP concrete pump characteristics and price are closely related. The cost is influenced by technical indicators and the ability of the machine to quickly deliver the solution to the desired construction point.

In addition, when selling cars on the secondary market, a significant role will be played by the operating hours, the year of manufacture of the KSR and the boom length along the reach.

Let's take a KCP concrete pump, the price of model 37rx170 is 10,200,000.00 rubles. A KCP58ZX170 truck-mounted concrete pump with a boom reach of 58 meters will cost a potential customer some 15,525,000 rubles.

Volvo concrete pump technical characteristics of the distributing boom and its capabilities

The dispensing boom, the reach of which can vary, consists of several sections. Their number varies from 3 to 5 pieces. Depending on the type of installation, there can be “Z” or “R” shapes. There is a combination of styling “RZ”. The boom can extend horizontally or vertically. The reach length of the working part of the boom ranges from 10 to 64 meters.

Operating principle

Volvo concrete pump drawings, boom work can be found on the Internet, it works as follows.

The concrete mixture is fed from the mixer. Next, the solution enters the botton drainage system. The pumping unit is responsible for this process. Delivery of the finished concrete product is carried out to the workplace using a sliding boom.

If it is necessary to supply the solution to a hard-to-reach workplace, a temporary pipeline is installed. The feeding and laying process is controlled using a radio remote control.

Methods of placing concrete pumps

The main difference between the units is the base options. There are automobile, mobile (mini) and stationary concrete pumps.

Automotive equipment

High mobility makes it possible to use this option even if construction is carried out on sites as far as possible from the benefits of civilization. This is a vehicle (usually a truck) that has a special platform on which a pumping station with a concrete pipeline already connected to it is securely fixed.

The main components of a concrete pump are a concrete receiving hopper and a boom. The last element is a steel pipe that has several sections called elbows. The length that such an arrow is capable of “rising” is 10-64 m. Its last element is connected to a flexible hose, in slang it is called a trunk. It makes it possible to direct a stream of solution to a given location. Before starting up the equipment, a certain amount of laitance or a special chemical (starting) solution is poured into it to lubricate the pipes.

Advantages of a truck-mounted concrete pump:

• maximum pumping length - up to 200 m, height - up to 70 m;
• maximum productivity (up to 90 cubic meters per hour);
• no need to find suitable transport;
• relative compactness of the station;
• Great maneuverability.

Flaws:

• expensive rent;
• insufficient feed height when compared with the “stationary” one.

Stationary concrete pumps

Such units are called stationary conventionally, since most of them still have the ability to move, but do not know how to move without assistance. The first example is a trailer on which a concrete pumping station is installed. It is transported using special equipment - a tractor.

Installing the unit on a separate site makes it possible to make the concrete pump more powerful, since the concrete pipeline - a long flexible hose - is installed directly on the construction site. This type of pump is used in the construction of multi-story buildings and high-rise buildings. Often, for more efficient operation, concrete pipes can be hung on a construction crane.

Completely stationary concrete pumps, which are installed on a permanent foundation, are a technique used in concrete factories. However, in these cases, belt conveyors or buckets are used, moved by cranes (gantry, bridge).

Advantages of stationary and “semi-stationary” trailed type:

• the ability to pump a very large amount of concrete mixture, when compared with concrete pumps (200 or more cubic meters per hour);
• the maximum solution supply distance is 300 m horizontally, 100 m vertically;
• different ways of supplying the solution: both horizontally and vertically;
• low price.

Minuses:

insufficient maneuverability; inability to quickly transport the unit; risk of damaging the hose due to careless or very frequent use.

On stationary units and on those installed on car trailers, piston systems are used, to which this type of equipment owes the highest performance.

Special concrete pumps

There are truck-mounted concrete pumps equipped with a mixer, but the maximum vertical pumping capacity of this type of equipment is small - only 30 m. There is another type of equipment - special, its tasks are far from being called trivial. For example, they produce mobile concrete pumps with caterpillar tracks. They are often used together with drilling machines. There is no replacement for such equipment for the construction of tunnels in mountainous areas.

Other examples are combined installations that produce and pump the solution, concrete pumps that have a hydraulic manipulator for spraying the mixture onto various surfaces. This list can be continued, since irreplaceable concrete mixtures are used very widely. Special equipment is being developed in Russia (Stroymash Center), Germany (Putzmeister AG), Italy (CIFA, Mecbo) and China (MITSUBER, XCMG).

Mobile mini-stations

This option is used when a relatively small amount of concrete is needed. Mini-pumps specialize in helping with the construction of small and medium-sized facilities. Its small size makes it easy to move the concrete pump around the site, making work quick and relatively easy.

However, for such super-maneuverability, mini-equipment pays with worse technical characteristics - maximum height and feed length. The first is 50 m, the second is 150. However, in private construction, these disadvantages, as a rule, are not disadvantages.

Classification of concrete pumps by mobility

In addition to the fact that concrete pumps differ in the method by which the mixture is supplied, they are also divided by mobility.

Mobile concrete pumps

Most often they are mounted on a truck base. The concrete pump is driven directly through the power take-off shaft or through an intermediate hydraulic pump (hydraulic transmission).

Additionally, you can watch how a concrete pump works in the video below.

Self-propelled concrete pumps mounted on a tracked chassis are very rare. They are used in conditions where the construction site or the entrances to it make it difficult to move standard equipment. Such installations are delivered over long distances on trawls.

Mobile concrete pump with high capacity on a crawler chassis

Almost always, mobile installations are equipped with a retractable, controlled boom with a concrete pipeline.

Concrete pump based on KAMAZ with a boom

Its reach can reach up to 30 meters, and for some models based on special heavy-duty vehicles, even more. However, they can also be connected to stationary concrete pipelines already installed on the construction site.

The boom of a concrete pump can have a decent reach

There are models mounted on the basis of a concrete mixer truck (often called a mixer) as additional equipment. In this case, they combine the functions of transporting concrete from the place of its preparation and a device for laying it in formwork.

Stationary concrete pumps

Most of these units can be called conditionally stationary, since they still have some mobility. Typically mounted on a wheeled chassis that can be towed.

If we consider the most popular industrial stationary concrete pump, its technical characteristics are approximately equal to those discussed above, however, the price is much lower, since it does not include the cost of the base vehicle itself.

Small towed concrete pump with self-contained motor and chassis

Completely stationary concrete pumps installed on a durable base can be used in concrete factories to supply the mixture for the molding of products and structures. But most industries use either conveyor belts or buckets that are moved by overhead and gantry cranes.

An internal combustion engine is installed to drive the pump. For low-capacity installations, it is often gasoline-powered; more powerful installations are equipped with diesel engines. There are also models that are powered by an electric motor, which is a more economical approach, but can cause some difficulties (except for pumps which, as mentioned above, are completely stationary).

The thing is that most concrete work is carried out during the construction of the zero cycle (foundation and foundation). At this stage, there may be no power supply at the site and it will have to be installed in advance. Although it should be noted that when supplying concrete using a tower crane and a bucket, you cannot do without electrification of the work site.

Stationary concrete pumps usually have higher productivity than mobile ones and are used for large volumes of work. Most often, concrete is supplied through a stationary concrete pipeline, although there are varieties with installed booms. Also, in many cases, pipes for supplying the mixture can be suspended from a construction crane.

1. In the horizontal direction.
2. Vertical feed.

Point supply occurs directly to the required workplace on construction sites, regardless of their area.

The lineup. Everything for concrete production from a single source

For the production of freshly prepared concrete and its delivery to the discharge point, it has in its arsenal a large number of varied equipment, which differ in a number of indicators. This can be the height of supply of concrete mixtures horizontally and vertically. Much depends on the number of folding sections. And other technical indicators. Drawings of SCHWING concrete pumps are available on the Internet.

Technical indicators for each model separately have been published on the Internet. Russian specialists know 16 models. It is actively exploited in Russia and the post-Soviet space. Photos of SCHWING concrete pumps are located at the end of the publication.

Price of SCHWING concrete pumps

The cost of new SCHWING concrete pumps is very high. German technology is of high quality, but you have to pay for quality. In Russia, you will have to pay 9,000,000.00 rubles for a new car. We are talking about the Schwing bpl 1200 HDR 23 kvm 52 model.

A 2001 German company concrete pump is sold for RUB 622,000.00. They offer to purchase a concrete pump manufactured in 1994 “for a ridiculous” 4,480,000.00 rubles.

As you can see, prices are high even for used equipment. Therefore, most construction organizations rent machines. No one denies the quality and other advantages of German technology. But not everyone has free funds to buy.

Types of installations

Stationary concrete pumps

Several types of concrete pumps are used in the construction industry, which is regulated by GOST ISO 21573-1-2013. They may differ in the following characteristics:

Engine type

Stationary units can be powered by a diesel or electric motor. Equipment equipped with electric motors is usually used on closed construction sites.

Electrical installation

However, it is not particularly popular in our country due to the lack of access to electricity, which is typical for many construction sites. Therefore, models with diesel engines are more popular.

Diesel unit

type of drive

Operating principle of concrete pumps with two types of wires

Concrete pumps can operate using mechanical or hydraulic drives. Today, most models are equipped with a hydraulic system. It can create more pressure, which leads to an increase in pump power and the distance over which the mixture can be transported.

Also, the advantages of hydraulics include an increased and smoother stroke of the working piston, ensuring uniform movement of the mixture along the concrete pipeline.

Pump design

Piston and rotary concrete pumps are used to supply concrete solution. The type of equipment is selected based on the specific task.

Piston concrete pumps

The principle of operation is that the solution is sucked in, after which the concrete is pushed out into the concrete pipe by the return movement of the piston. Piston units have greater productivity compared to rotary units.

But they are subject to rapid wear due to the penetration of concrete milk and small filler particles into the mechanism. Also, a disadvantage of such a system is the uneven supply of the solution, which in many cases is unacceptable.

Construction of a piston concrete pump

Rotary concrete pumps

The concrete mixture in these units is moved to the concrete pipe using rubber-coated rollers mounted on a rotor. This system makes it possible to use mixtures with coarse aggregate.

Concrete pumps operating on this principle have a low noise level. When congestion occurs from the concrete mixture, reverse can be started inside the concrete pipeline (the movement of the solution in the opposite direction).

Scheme of a rotary concrete pump

Rotary equipment is intended, as a rule, for small volumes of work. It is more convenient to use such units at sites where frequent reinforcement is performed during concreting. In rotary systems, a pressing problem is increased wear of hoses, which is damaged by aggregate, especially crushed stone.

An important part of the pumping system is the gate. It provides access for the mixture to the concrete pipeline or, conversely, blocks the road

Three types of such valves are used:

1. C-shaped.
2. S-shaped.
3. Rock gate.

The first two types of valves are made from steel and cast iron, the latter - exclusively from cast iron.
