2. Key indicators for selecting high-rise concrete pump trucks
According to the latest data from the China Construction Machinery Association, the types of pump trucks corresponding to buildings of different heights are selected as follows:
| building height | Recommended pump truck models | Outlet pressure (MPa) | Theoretical conveying capacity (m³/h) |
|---|---|---|---|
| ≤100 meters | Zoomlion 56 meters | 12-16 | 90-120 |
| 100-200 meters | Sany Heavy Industry 86 meters | 22-28 | 60-80 |
| 200-300 meters | XCMG ultra-high pressure pump | 35-42 | 40-60 |
| ≥300 meters | Putzmeister M70 | 48-56 | 30-45 |
3. Analysis of three popular technologies
1.Ultra-high pressure pumping system: The newly released SY5318THBFS 86X-8RZ pump truck adopts four-stage hydraulic boosting technology, with a measured vertical pumping height of 603 meters, setting a new record in the industry.
2.New energy solutions: The electric pump truck series launched by Sany Group can work continuously for 8 hours after charging for 1 hour, and the noise is reduced by 60%. It is especially suitable for projects with high urban environmental protection requirements.
3.Intelligent security control: The "Smart Eye" system developed by Zoomlion monitors the stress status of the outriggers in real time through 12 sensors, automatically calculates the safe operating range, and reduces the accident rate by 85%.
4. Performance comparison of mainstream brands in the market
| brand | Star product | maximum height | Fuel consumption (L/h) | Price range (10,000) |
|---|---|---|---|---|
| Sany Heavy Industry | SYM5418THB | 86 meters | 28-35 | 380-450 |
| Zoomlion | ZLJ5440THB | 80 meters | 30-38 | 360-420 |
| XCMG Machinery | XZJ5520THB | 75 meters | 25-32 | 340-400 |
| Putzmeister | M70-5 | 70 meters | 22-28 | 450-520 |
5. Operation precautions
1. When pumping high-strength concrete above C60, it is recommended that the pressure does not exceed 80% of the rated value.
2. During summer construction, the hydraulic oil temperature needs to be checked every 2 hours. If it exceeds 85°C, the machine should be shut down for cooling.
3. For high-level pumping, it is recommended to use S valve series pump trucks, whose reversing impact is 40% smaller than that of gate valves.
4. The first 200 hours of new equipment are the running-in period, and the conveying volume is recommended to be controlled within 70% of the rated value.
Conclusion:When choosing a high-rise concrete pump truck, multiple factors such as building height, concrete grade, and construction environment must be comprehensively considered. It is recommended to give priority to equipment with intelligent control systems and high-pressure pumping technology, while paying attention to the energy consumption performance of the equipment and the after-sales service network. As the "double carbon" goal advances, new energy pump trucks will become an important development direction of the future market.
