What Is Small Portable Concrete Pumping Machine

 The small portable concrete pumping machine has two kinds: truck mounted concrete pump and concrete boom pump truck. What are their differences and advantages? Lets have a look together.

The truck mounted concrete pump is an upgraded version of the concrete pump trailer. It adds a car chassis and a generator set. If you need to transfer between different construction sites, it is more suitable to choose a truck-mounted pump, because it can drive fast on the road.

Since it has no boom, manual piping is required when in use. In addition, on the construction site, for those medium and high-rise buildings that are difficult to reach by the boom pump, the truck mounted concrete pump can also be used to pump the concrete to the concrete pump, but the premise is that the concrete pump has enough power and the of the pipelines can reach the required height.

Concrete boom pump is a device that integrates the pumping system for pumping concrete and the boom system for placing on the chassis of the vehicle. The pumping system uses the power of the chassis engine to pressurize the concrete inside the pipeline which is attached to the boom. The operator controls the movement of the boom to deliver the concrete pumped by the pumping system directly to the pouring point.

The small concrete pump truck is a kind of concrete machinery equipment that is convenient to move and distribute. However, according to different working conditions, the requirements for the small concrete pump truck are different, so in the construction process, the selection of the concrete pump truck is very important.

In some narrow areas in the countryside, the overly long boom is not easy to perform due to the size of the space. Therefore, it is necessary to select the appropriate boom length of the small pumping machine for rural construction. 25-42 meter concrete boom truck is more suitable for rural projects.

It is need to make clear of the theoretical pumping volume. The theoretical pumping volume is the data obtained under the most severe conditions in the laboratory. Therefore, the actual pumping volume per unit time must be smaller than this. If you don't which model to choose, just tell our sales your needed actual pumping volume.

Which to Buy: New or Used Self Loading Mobile Concrete Mixer

 Investing in a used self loading mobile concrete mixer has no advantages except that the investment capital will be less than that of a new self loading concrete mixer truck. The second-hand self loading concrete mixer will generate a lot of maintenance costs during use.

The longer the term, the faster the depreciation. Generally, after two or three years, the depreciation rate of the self loading mixer truck is very fast. Work efficiency is also showing a downward trend. Therefore, if conditions permit, you should still buy a new self loading concrete mixer.

Generally, the service life of a new self loading transit mixer is about 10 years. The self-loading mixer truck can replace 6 workers. One batch only take 12 minutes to achieve the purpose of convenient concrete production. It is suitable for small and medium-sized projects, especially for projects with short and tight construction periods, insufficient manpower, and small profit.

Haomei self loading concrete mixer mainly has a volume of 1.2m3, 1.8m3, 2.0m3, 2.6m3, 3.5m3, and 4.0m3. According to the different volumes, the daily productivity of Haomei self loading mixer is about 50-200 cubic meters. Customers can choose according to the daily volume of concrete required. Of course, different models also have different configurations. Air conditioning, automatic lubrication system, electronic weighing, tank rotation functions are all optional.

A good seat can bring the driver a suitable sitting posture, which is related to the safety of operation. In the new self mixing concrete truck, Haomei engineers upgraded all the seats to airbag seats according to the principle of man-machine friendly relationship. Under the action of the double tubes of the airbag and the spring, the shock absorption effect is excellent, especially suitable for high-intensity operations while alleviating the driver's operating fatigue.

As for the weakness of the self mixing concrete truck, when feeding, sand and stones will rub against the feeding. Scratches will be formed on the bottom and inside. In addition, it should be noted that the screw parts on the body will become loose due to frequent vibration that will affect the working efficiency of the mixer truck and cause certain adverse effects. Therefore, workers should always check and tighten loose screws to avoid the formation of hazards.

How to Install Hot Mix Asphalt Equipment

 As one of the most common materials in road construction, asphalt plays an important role. Hot mix asphalt equipment is an an important equipment for highway construction, which integrates various technologies such as machinery, electricity and automation. The production capacity, measurement accuracy, degree of automation of the control system, reliability of mechanical transmission and energy consumption rate of the asphalt mixing plant are closely related to the installation of the hot mix asphalt plant for sale.

The installation of asphalt mixing plant refers to the installation of asphalt mixing plant carried out by relevant departments in order to ensure the effective, stable, safe and high-quality construction during the construction process.

The main content includes: the installation of control system, dust removal system, powder supply system, asphalt supply system, weighing and mixing system, hot material storage bin, vibrating screen, hot material lifting, fuel system, drying system and batching system. The installation activity of asphalt batching plant is the basic work of the whole construction process and has its own characteristics.

For the installation of bitumen plant, the first work is to select the site for the installation of asphalt mixing plant. In the process of site selection, we must fully consider the specific construction conditions and construction sites, and try to avoid the impact of the asphalt mixing plant on the surrounding environment and residents. Therefore, we should try to avoid environmental protection districts and residential areas.

In production, the vibrating screen, mixing tank and aggregate drying cylinder are the components that generate the most intense vibration in the whole set of equipment, which has a certain impact on the entire mixing plant. Therefore, when we carry out foundation construction, we should pay special attention to the quality of the aggregate drying drum and the main building part, so as to ensure the stability of the main building part, and resolutely avoid damage to the entire asphalt plant due to irregular construction activities and inadequate construction management monitoring.

The installation of electrical equipment is the key content of the installation of the entire asphalt mixing plant, so it must be regulated and guided. In order to adapt to large-scale construction, it is necessary to increase the power of the electrical equipment of the entire asphalt mixing plant, especially the electrical equipment. At present, the power consumption of most asphalt mixing plants has reached 600kW-1000kW.

Compared with the installation of the stationary asphalt plant, that of hot mix mobile plant is easier and quicker. Welcome to leave message to inquire what you need.

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.
