The Development of Truck Mounted Concrete Boom Pump in China
Jul 15, 2020
In recent years, our truck mounted concrete boom pump has developed rapidly in terms of stability and manufacturing technology. In addition, it has obvious competitive advantages in terms of cost performance and after-sales service. What are its developing trends?
1. Rich choices of the chassis
The chassis provides power for the work and driving of the concrete pump long boom. Therefore, the performance of the chassis engine directly affects the performance of the whole pump truck. At present, Volvo, Mercedes-Benz and Isuzu chassis are commonly used in domestic long boom concrete pump, which have reached Euro II or higher standards.
2. The structural parts are more applicable
The truck mounted concrete pumps are often limited by the upper space during operation. Due to space constraints, the boom with more than 5 sections is generally of RZ combination folding type to realize the expansion and contraction of the boom.
Its mobility and flexibility are enhanced, especially in the construction of tunnels and indoor operations. Longer boom and more flexible outrigger structure are the main trends of boom pump truck for sale.
3. The central pumping system has higher pressure and greater throughput.
At present, the most common delivery cylinder diameter in the market is 230mm, the stroke is 2100mm or even longer, and the output displacement is more than 120m3/h. As the boom of the concrete pump truck is higher and the model is larger, the cylinder diameter of the conveying cylinder is larger.
4. The Hydraulic system is towards integration
The hydraulic system is the core part of the boom concrete pump truck. The quality of the hydraulic system will directly affect the working performance and efficiency of the main engine. The concrete pump truck generally adopts an open system and constant power control. The open system has many advantages such as low oil temperature, high reliability, and easy maintenance.
5. Multi-functional control system
Electrical control is the key to determine the efficiency of the pump truck. The electrical system of the pump truck has developed rapidly in the past two years. Various domestic manufacturers have improved from the initial relay control to the PLC control, which has greatly improved the reliability of the concrete pump truck with boom.
Now the concrete boom pump truck develops in the direction of more complete specifications, higher grades, and longer booms. The boom has gradually changed from 37m as the mainstream to 42 meter concrete pump-45 meter, and it has developed in the direction of 47- 56 meter.
