What Is The Chassis of Long Boom Concrete Pump Truck

 After more than 20 years of development, the current design level and manufacturing capabilities of Chinese concrete boom pump have been greatly improved. However, among the three most important components of a pump truck - chassis, pump and boom, parts of customers or manufacturers still prefer to use imported products. Especially when choosing a pump truck chassis, imported products are particularly favored.

When users choose a pump truck chassis, in addition to price, they will also consider four important factors: The first is the brand. Competition in the construction field is fierce, and most long boom concrete pump users will believe that vehicles of well-known brands will bring an advantage to their business bidding.

The second is the reliability of the vehicle. Due to the high work intensity of the pump truck, the requirements for the durability and integrity of the chassis are very high. Once the chassis fails, it will bring not only maintenance costs, but also the economic benefits of the user will be seriously affected.

The third is after-sales service. The special use environment of concrete pump trucks has very high requirements for after-sales service. Whether the after-sales service is timely will even determine whether the construction contract contracted by the user can be successfully completed.

The fourth is fuel economy. Today, as fuel prices continue to rise, pump truck fuel consumption is also a factor that customers have to consider. The level of fuel consumption will also have a certain impact on vehicle sales.

For concrete pump truck manufacturing companies, they are also faced with the problem of chassis selection. With the development of the market, the manufacturing of pump trucks has shown a trend of diversification. The length of the boom is getting longer and longer, and the load capacity is also getting larger and larger. Therefore, when selecting the supporting chassis, the concrete pump truck manufacturer also put forward some requirements accordingly:

1. The engine power output should match bodywork design requirements. The designer of the pump truck's upper body should select the appropriate engine power based on the outlet pressure and torque requirements of the designed upper body. If the two do not match, there will be problems such as the pump truck slowing down in actual work.

2. Choose choose the correct modified chassis according to different design weights and different boom lengths. The design of a pump truck must not only consider the working conditions of its upper body but also the safety of its road driving. Therefore, the matching chassis form must be selected according to the load distribution and national regulations.

For example: Generally, a pump truck with an arm length of less than 27 m uses a 2-axis chassis, a pump truck with an arm length of 27 m to 37 m uses a 3-axis chassis, and a pump truck with an arm length of 42 m to 47 m uses a 4-axis chassis. If the length is more than 52 m, a 5-axis or 6-axis chassis is required.

3. Carry out vehicle modification work according to the modification instructions provided by the chassis manufacturer. For example, Volvo Truck Company can provide each modification company with modification instructions (CD-ROM) and has a professional website to provide support for modification work.

It is precisely based on the dual choices of users and pump truck manufacturing companies that imported brand pump truck chassis have always been popular. Haomei Machinery’s boom concrete pump truck has different brands of chassis for you to choose from like Volvo, HOWO, Benz,etc.

Hot Mix Asphalt Machine: Asphalt Drum Plant

 

Types of asphalt concrete

Asphalt concrete pavement should use appropriate hot mix asphalt mixture according to usage conditions, environment, construction conditions, pavement properties, highway grade, etc. The following types are commonly used:

1. Ordinary asphalt mixture

That is AC type asphalt mixture, which is suitable for urban secondary roads, auxiliary roads or sidewalks.

2. Modified asphalt mixture

Modified asphalt mixture refers to an asphalt mixture made by adding rubber, resin, high molecular polymer, finely ground rubber powder or other fillers and other additives (modifiers) to improve the performance of asphalt or asphalt mixture.

Compared with AC-type asphalt mixture, modified asphalt mixture has higher high-temperature rutting resistance, good low-temperature resistance to cracking, higher wear resistance and longer service life. The modified asphalt mixture surface layer is suitable for urban expressways and trunk roads.

3. Asphalt masculine mixture (SMA for short)

SMA mixture is a mixture composed of asphalt, mineral powder and fiber stabilizer, which is filled in the discontinuous skeleton. SMA is a discontinuously graded asphalt mixture. The proportion of coarse aggregate over 5mm is as high as 70%~80%, the amount of mineral powder is 7%~13% and the amount of asphalt is relatively high, up to 6.5%~7%.

SMA is an asphalt surface mixture with strong deformation resistance and good durability that is currently used at home and abroad; it is suitable for urban expressways and main roads.

4. Modified (asphalt) asphalt masala gravel mixture

This type uses modified asphalt and adopts SMA structure type. It has very good high-temperature anti-rutting performance, low-temperature anti-deformation performance and water stability, and has a large structural depth, good anti-skid performance, and greatly improved aging resistance and durability.

Types of asphalt mixing plants

The hot mix asphalt machine is a complete set of equipment used for batch production of asphalt concrete. The asphalt mixing station uses aggregate, powder and asphalt as raw materials and mixes them according to a certain mix ratio. According to the mixing method, it can be divided into batch type and continuous type. According to the transportation method, it can be divided into stationary, mobile and semi-fixed.

The quality control of asphalt mixing plant

1. Asphalt temperature control

Asphalt temperature is one of the important factors affecting the quality of asphalt mixture. During the production process, the temperature of asphalt must be strictly controlled to ensure that it is within the specified range. Generally speaking, the temperature of asphalt should be maintained between 130℃-170℃.

2. Aggregate gradation control

Aggregate gradation is an important indicator of asphalt mixture, which directly affects the strength and stability of the mixture. During the production process, the gradation of aggregates must be controlled through testing and inspection to ensure that it meets specified requirements.

3. Asphalt mixture oil-stone ratio control

The asphalt mixture oil-stone ratio refers to the ratio of the mass of asphalt in the asphalt mixture to the total mass of aggregates and fillers. During the production process, batching must be carried out in strict accordance with the design requirements of the oil-stone ratio, and the oil-stone ratio must be controlled through testing and inspection.

4. Mixing time control

The length of mixing time also affects the quality of asphalt mixture. During the production process, mixing must be carried out strictly in accordance with the mixing time requirements to achieve a uniform and consistent effect.

5. Equipment maintenance

The asphalt drum plant maintenance is also one of the important factors to ensure the quality of asphalt mixing plants. Equipment must be inspected and maintained regularly to ensure the integrity of the equipment and the stability of its operation.

How to Maintain Self Loading Mobile Concrete Mixer

 Driving a self loading mobile concrete mixer is a task that requires a high level of concentration and skill, as these vehicles have important safety and stability requirements when transporting concrete. There are some tips:

self loading mobile concrete mixer .jpg

1. Familiarize yourself with the vehicle: Before driving the self loading concrete mixer truck, make sure you are familiar with all the vehicle's controls and instruments and have a clear understanding of the vehicle's size, weight, and any potential mechanical issues.

2. Driver Training: Receive specialized training on how to properly operate and drive this type of vehicle. Be familiar with the driving characteristics and handling techniques of the vehicle.

3. Load limit: Strictly comply with the maximum load limit of the self loading mixer truck. Overloading reduces vehicle stability and increases the risk of accidents.

4. Vehicle inspection: Before each trip, all systems of the mixer truck must be carefully checked, including brakes, tires, suspension, mixing barrels, etc., to ensure that all equipment is working properly.

Engine maintenance

It is inseparable from engine oil. The engine oil of self-loading mixers is a consumable. For mixer trucks that are often used on construction sites, the maintenance of engine oil is even more important. So what methods can be used to extend the oil cycle of self-loading mixer trucks?

1. Prevent fuel from leaking into the oil pan, because the fuel pan will dilute the engine oil, thereby greatly reducing the viscosity of the engine oil and losing the lubrication effect prematurely. Therefore, diesel engines require sufficient fuel supply pressure from the fuel injection pump, good atomization of the injector, and reasonable throttle control to ensure complete fuel combustion.

2. Avoid operating the engine in a high-temperature environment. The engine generally requires a normal operating temperature of 80°C to 95°C. If the temperature is too high, the engine oil will become thinner and the engine oil will deteriorate faster. Once the temperature is found to be too high, it must be stopped for inspection, and normal work can continue until the fault is eliminated.

HOW TO CLEAN THE VEHICLE AFTER USING

After use, it is very important to clean the self loading transit mixer promptly and thoroughly to ensure that no concrete residue accumulates or is clogged inside the mixing drum, while maintaining the operating efficiency of the vehicle and the quality of the concrete. The following are general cleaning steps:

Drive away from the construction site: Before starting cleaning, drive the mixer truck away from the construction site to ensure that no new concrete is poured into the mixing drum.

Dumping Concrete Residues: At a cleaning station or designated dumping area, completely dump the mixer drum to remove all concrete residue.

Inject clean water: Inject an appropriate amount of clean water into the mixing drum, then start the mixing drum and let the clean water rotate in the mixing drum to clean the drum wall and mixing blades.

High-pressure flushing: If conditions permit, you can use a high-pressure water gun to flush the mixing drum to more thoroughly remove residual concrete and dirt.

Repeated cleaning: If there are still stubborn concrete residues in the mixing drum, you can clean it multiple times until the inside is clean and free of residue.

Clean the exterior: In addition to the inside of the mixing drum, you also need to clean the exterior of the vehicle, including the body and tires. Cleaning the exterior helps prevent concrete from hardening and vehicle corrosion.

Inspection and maintenance: During the cleaning process, check the hydraulic system, rotating device and other key components of the mixer truck for abnormalities or damage. If problems are found, repair them in time.

Storage and maintenance: After cleaning, the self propelled concrete mixer truck should be stored in a dry, well-ventilated place. Carry out regular maintenance and upkeep on the mixer truck to ensure long-term reliable operation of the vehicle.

At the construction site, there should be a designated cleaning area to avoid direct discharge of sewage into the environment. In addition, relevant safety operating procedures must also be followed to ensure that no harm is caused to operators during the cleaning process.
