Energy-saving environmental protection into the development of a new trend of concrete pump truck - concrete pump, energy saving - construction machinery industry

China Suppliers


Concrete pump is an important tool for the construction industry, as domestic concrete industry and construction machinery Lease The rapid business development and expansion of scale and scope of construction, coupled with the development of the west and northeast old industrial base have started construction of a concrete drive Conveyor The rapid development of mechanical, concrete pump truck market space has also been further expanded.





Present, the major users of concrete pump truck bodies are annual production capacity of 300,000 cubic meters of concrete more than qualified suppliers, industry, the larger construction units, a certain economic strength and scale of construction machinery enterprises, construction units from the original separation of the equipment management sector; individual users are mainly the developed coastal regions of individual mixing stations and the Ministry of individual machinery rental. Domestic groups with at least 800 more users, according to international conventional size every five, the next few years the pump has a capacity will reach around 4000, together with the individual user's 1000, this figure is very impressive.

Boom concrete pump technology is a key technology in the past has been to Germany, the United States and a few developed countries to control manufacturing enterprises. 2003 Sany Heavy Industry Developed a 56 m boom pump, in one fell swoop became the world capable of producing the long arm pump in the three companies. Currently, the domestic production of such products form spectrum and the growing business, product performance, quality in rapidly. With mixed concrete industry, concrete pumping machinery specifications and more comprehensive, higher grade, pump arm fabric direction towards a longer, 37 meters from the past mainstream though, and gradually transition to 42 to 45 meters Lord, 47 ~ and 56 meters the marketplace favor. This year in January, Sany Heavy Industry has developed a maximum vertical height of 66 m boom pump, as the world's longest boom pump one.





According to experts, with the progress of the works to speed up, pumping concrete pump truck emission requirements have increased over the past emission in 60 to 80 cubic meters per hour, about 60%, emissions requirements now 80 to 120 cubic meters per hour, more and more projects, such as the Hangzhou Bay Bridge used concrete pumps, emissions are basically the 120 cubic meters per hour.





Currently, users of mobile concrete pumps have become increasingly demanding, mainly in the truck market needs fast growth. In addition, Car Pump The market is also active, Sany Heavy Industry, Chutian machinery, Zoomlion, HONGDELI other manufacturers have a new listing. Currently, Diesel engine More and more power, pump, and car not only require the use of pumps Diesel engine Power, Single-drag pump gradually increase the proportion.





Hydraulic system to the integration direction, commonly used open system and constant power control, especially in high-volume pump, open system with low temperature and high-reliability, easy maintenance and many other advantages. Meanwhile, the full hydraulic control technology, computer control technology breakthrough has been made. Sany Heavy Industry products such as hydraulic and computer for the closed-loop control technology has been widely used, has had a significant increase pumping pressure, but also continue to improve the trend. Meanwhile, the hydraulic system pressure is also rising, basically more than 32 MPa. Therefore, the transmission distance has also increased the maximum level of transmission distance over 2000 meters, the maximum vertical pumping height of 500 meters.





Improve equipment energy efficiency, environmental performance is a major trend, the wind cooling gradually to replace the water cooling, Engine Emission standards to improve, mostly to Europe or Euro standard.





Further attention to the reliability of concrete pumps, mainly for high strength, large aggregate, 3 research with concrete, is now able to pump a minimum slump of concrete is only 20 mm, the maximum aggregate size can be 80 ~ 120 mm. If Sany HBT120A-1410D 3 with concrete pump, has been successfully applied to the construction of Three Gorges Project.





In addition to equipment design, manufacturing has made great progress, the level of use and maintenance of equipment has also been a corresponding increase in the use of personnel on the principle of concrete pumping machinery, structure, operation and routine maintenance more familiar with the equipment in the construction process to make them handy to use, the role is also growing.
