The Boom Length of Small Concrete Pump Truck

 The small concrete pump truck is a kind of concrete equipment that can use its own boom to pump concrete. Because of the built-in boom, the process of taking over and dismantling the pipe is omitted, which makes the construction process more streamlined and greatly reduces the intensity of the workers' construction. In addition, the small boom pump truck has a wide range of applications, not only for urban construction, but also for concrete construction in rural areas.

According to the height of the boom of the pump truck, the concrete pump truck can be divided into: short boom, long boom and super long boom. The boom height of 13-28meter is for the short boom concrete pump; 31-47 meter is for the the long boom concrete pump, 51-62 meter is for the super-long boom concrete truck.

It is better to use a small concrete pump truck between 25 meters and 42 meters for concrete construction in rural areas. If the boom is too short, it is difficult to to meet the needs of rural construction; if it is too long, it will lead to waste of cost. In some narrow areas in rural areas, the too long boom is limited by the size of the space and is not easy to stretch. Therefore, it is necessary to choose the appropriate boom length of the small concrete pump truck for rural construction.

The boom frame and the master cylinder use a hydraulic system. However, different brands of pump trucks also have differences in hydraulic systems. A good hydraulic system can generate greater working pressure, and has the advantages of small conversion impact and easy control.

Different brands have different prices. This is due to the different production processes of major manufacturers and the different quality of boom pressure concrete pump, which directly affects the boom pressure concrete pump price. Usually, the price of large manufacturers is higher than that of small and medium-sized enterprises, and their corresponding service measures are also better.

However, there are also some small and medium-sized concrete boom pump manufacturers like Haomei Machinreiy that are very popular among users due to their excellent quality and reasonable price. Its main parts are of world-class brands, and the production technology is excellent, so the products sold have received good response.

How to Warm Up the Self Loading Concrete Truck

 The usual way to warm up the self loading concrete truck is finished when the engine is running. After the hydraulic pump works passively for a period of time, the temperature of the hydraulic oil rises to the specified value, the viscosity of the hydraulic oil reaches the normal working state, and the preheating of the self loading transit mixer is finished.

This recognized preheating operation method seems simple, but it is not. If the preheating operation of the self loading mixer is carried out in the correct state, the wear and failure rate of the hydraulic system of the car body can be effectively reduced. On the contrary, incorrect warm-up behavior will inevitably increase the wear and tear of the equipment.

In the early stage of warm-up, the main oil pump of the self loading concrete mixer must keep running dry. There are generally four types of hydraulic pumps installed in the hydraulic system on self-loading mixer trucks, namely the main oil pump, balance pressure pump, mixing pump and boom pump. In terms of the working principle of the hydraulic pump, except for the mixing pump which belongs to the gear pump, the other three pumps belong to the swash plate plunger pump. In comparison, the performance of the swash plate plunger pump is better than that of the gear pump, and the precision is higher and the price is higher, so more attention should be paid to it.

For self loading concrete mixer truck with different working principles, the operation method of letting the main oil pump run dry is different. In the current common concrete pumping hydraulic system, there are two main types - open system and closed system.

For the self-loading mixer truck of the open system, the pumping displacement can be set at the "zero" position when the top-mounted power take-off is turned on. Depending on the brand and age of your self-loading mixer, the setup method may vary slightly.

For a self propelled concrete mixer with a closed system, the method is relatively simple, that is, when the power take-off of the body is turned on, the pumping is kept in a stopped state.

In the later stage of warm-up, the displacement of the main oil pump gradually increases. During the idling process of the hydraulic pump of the self propelled concrete mixer, the bearings, oil distribution plate and other components will inevitably heat up due to motion friction. The heat is gradually transferred to the surrounding hydraulic oil, so that the temperature of the hydraulic oil gradually increases and the viscosity gradually decreases.

After a period of time, the swash plate of the hydraulic pump can be adjusted to a small angle to make the hydraulic oil flow, so that the hydraulic oil with a higher temperature is sent into the hydraulic circuit.

Due to convection and conduction, the oil in the hydraulic motor and pipeline gradually heats up. The preheating work is not successfully completed until the hydraulic oil of the entire pumping system reaches the working temperature.

ADVANTAGES:

1. It is relatively cheap compared with the total cost of buying concrete mixer and concrete pumps. The concrete mixing pump has two in one.

2. During the construction, the construction efficiency of the concrete mixing pump is very high. It can carry out on-site mixing and continuous pumping. Compared with traditional mixer mixing and manual feeding, the efficiency is increased by more than 5 times.

3. It saves labor during the operation and significantly reduces the cost of use. The whole process can be operated by one person with a high degree of automation. Compared with concrete mixer and manual feeding, it can save 4-5 labors.

4. The concrete mixer and pump is light, small in size and easy to move, which is very suitable for construction in rural areas and narrow areas.

5. The concrete produced by the concrete mixer pump is very good. Usually, the concrete produced by the concrete mixer pump needs to be mixed twice, which is more uniform, has better compactness, higher strength, and better impermeability and flexural resistance.

DISADVANTAGES

1. It takes a long time and a lot of work to prepare for laying pipelines.

2. As the pouring position changes, the placement point must be manually moved.

3. JBT 30 concrete mixer with pump does not have a motorized walking mechanism, so it needs to be dragged, and the moving speed is slow.

4. It is necessary to tow the supporting construction components during the transition: generator sets, trailer pump, pipelines, forklifts, rotating brackets and other tools. There are many mobile supporting equipment, which is not flexible enough.

Stationary Concrete Pump for Sale

The concrete pump trailer is a kind of stationary concrete pump for sale. It is used to pump concrete to the high-rise building. It only has the function of conveying. It is generally used in urban construction projects to pump the commercial concrete and is used in conjunction with concrete mixer trucks.

Concrete pumps can be divided into electric concrete pump and diesel concrete pump. In areas with normal power supply and construction sites, the power of the motor is better when it is stationary for a long time. The reason is that the cost of use is low. The power of the diesel engine is highly mobile and is not affected by the power supply. However, compared with the motor pump, the cost of use is slightly higher.

There are many factors that determine the pumping distance of the stationary concrete pump. The first is the maximum pumping pressure of the equipment, which directly determines the farthest pumping height and horizontal distance. For example, the maximum pumping pressure of the concrete trailer pump pumping C70 concrete to a height of 452 meters is 48Mpa.

Haomei ready mix concrete pump adopts S valve, which can meet the transportation of commercial concrete, and is not suitable for pipe blockage. The outlet pressure is high, and it can meet the transportation requirements of high-rise buildings and long-distance construction. The concrete pump is small in size and easy to move. The selected parking place should be a stable and hard ground.

The performance of the RMC pump is related to the model. When selecting the model, in addition to the amount of concrete pouring, the type and structure of the building, site conditions, construction technical requirements and surrounding environment should also be considered.

The main performance parameters of the concrete pump truck usually selected should be in line with the construction requirements or slightly larger. If the capacity is too large, the utilization rate will be low; if it is too small, it will not only fail to meet the construction requirements but also accelerate the loss of the concrete pump trailer. Welcome to leave message below to inquire RMC pump price.

Why Is Self Loading Transit Mixer So Powerful

 Self loading transit mixer with strong power is a multifunctional mixer truck integrating automatic feeding, mixing, unloading and water injection. It is mainly suitable for occasions where the space is relatively small, the road is narrow, and large mixer trucks are not easy to enter, such as in the construction of small and medium-sized projects in rural areas.

The self loading concrete mixer can transport concrete at short distances through the vehicle chassis, which eliminates the drawbacks of traditional mixers that need to be fixed in a certain site, then transported by other vehicles, and then unloaded on site.

Self loading transit mixer.jpg

The main advantages of self loading mixer

(1) Automatic feeding, automatic watering.

(2) It is suitable for different terrains and does not depend on electric equipment.

(3) High output speed of one batch in 5 minutes on average.

(4) The size of the model can be customized according to the output. The models ranges from HM1.2 to HM6.5. HM1.2 self loading mixer refers to the output per batch is 1.2m3.

In rural construction, many roads are only 3.5 meters wide, and many large vehicles are inconvenient to walk, but the small self loading transit mixer r can not only come and go freely, but also reduce a lot of labor. The road construction should have required a lot of labor to load material, unload concrete and paving, but with a small self container concrete mixer truck, only one person is required to operate the machine. Another worker is needed to pave the concrete.

Tips for safe use of self loading concrete mixer truck

1. It should implement secondary leakage protection. After the power is turned on before going to work, it must be carefully checked, and it can be used only after the empty truck is tested and deemed qualified. During the test run, check whether the rotating speed of the mixing drum is appropriate. In general, the speed of the empty vehicle is slightly faster than that of the heavy vehicle (after loading) by 2~3 revolutions. If there is a large difference, the ratio of the driving wheel to the driving wheel should be adjusted.

2. The rotation direction of the mixing drum of the self contained concrete mixer truck should conform to the direction indicated by the arrow. If it is not true, the motor wiring should be corrected.

3. Check whether the transmission clutch and brake are flexible and reliable, whether the wire rope is damaged, whether the track pulley is in good condition, whether there are obstacles.

A Highlight of Portable Hot Mix Asphalt Plant

 The hot mix asphalt plant for sale is a mechanical device used to produce various asphalt mixtures, and is a necessary equipment for the construction of roads, villages, urban roads, large airports, coastal ports, parking lots, and freight yards. Asphalt concrete mixing plant is an important equipment for producing asphalt concrete.

The portable hot mix asphalt plant is often used on smaller sites that need to be completed quickly. On these projects, setting up a stationary mixing plant would be a waste of time. It usually takes around 2 weeks to build this stationary concrete plant, which adds to the overall project timeline.

A mobile mixing plant will be much cheaper than a large stationary mixing plant. The cost savings will not be limited to the initial purchase cost. The cost of using mobile asphalt mixing equipment will also be greatly reduced.

The main body of mobile concrete batching plant is designed as four mobile modules, including mixing equipment module, grading barrel module, bag filter module and drying drum module. Each module comes with a mobile chassis that can be towed away by truck or tractor. Pre-connected with plug and socket cables in the factory reduces assembly time, while the self-contained metal base allows the asphalt plant to stand stably on the ground without the need for a concrete foundation.

The mobile drum mix plant is a continuous mixing equipment, and the first two-thirds of the unit of the drying drum is dedicated to dehumidification. In the last third of the drum is to mix the aggregate and asphalt.

The advantage of the drum asphalt mixing plant is to reduce the hot mixing process to the most basic requirements, and by eliminating most of the steps of mass production of the mixture, the drum asphalt mixing plant can do its job more economically.

The production of asphalt drum mix plant generally involves continuous dynamic metering of each component (crushed stone, sand, stone powder, asphalt, etc.) in proportion, continuous feeding and drum mixing. The process is continuous metering by weight (or volume) - continuous feeding - continuous drum drop mixing - continuous discharging. It has a high degree of automation, high-quality asphalt mixture preparation, good drying and heating effects, low residual moisture content in the finished material, and a wide range of applications.
