 Boom mounted concrete pump in China in recent years been rapid development, product stability and process, although not as good as abroad, but cost, service and other products of our country has a clear competitive advantage, and more in line with the actual construction of the domestic situation. Among them, Zoomlion, Sany Heavy Industry R & D arm mounted concrete pump truck to go in front of peers. The Zoomlion formulate a concrete pump truck standards, also developed a pump remote maintenance and positioning systems. SANY concrete pump truck, regardless of pump pressure, pump displacement, stability, reliability, can be abroad with the name brand products comparable to its pumping machinery products have been selling to the Middle East North Africa and South Asia. 

 123 pumping machinery patents released by the National Patent Office can be seen, domestic pumping machinery for the patent to the gate of the pump, pump and pump control, hydraulic, electrical and other, indicating that the domestic enterprises in these areas more emphasis on domestic pumping machinery is relatively weak field. Pump spare parts, and boom, the number of patents in the past 20 years only 100, which also includes foreign enterprises to apply for the patent, which shows China's business-to-bracket pumping machinery R & D investment in less than 

 Domestic arm mounted concrete pump because of a late start, the past two years, domestic enterprises have to strengthen the introduction of technology and quality control, design and development of independent intellectual property rights of the arm-mounted concrete pump, technological innovation has become the domestic arm mounted concrete booster pump development. The major components of the technology trends also represent the direction of development of the domestic arm mounted concrete pump vehicle. 

 The chassis engine for the arm-mounted concrete pump truck and driving power. Therefore, chassis, engine performance will directly affect the performance of the arm-mounted concrete pump truck. Bracket concrete pump truck used Volvo, Mercedes, Isuzu chassis, existing domestic chassis bracket concrete pump truck market in 2005. As the domestic arm mounted concrete pump market matures, the vehicle falling profit margins in order to meet the needs of different users, using the arm of domestic chassis and imported chassis mounted concrete pump will take up their place in the market . 

 The domestic arm mounted concrete pump selection of chassis are almost all imported chassis. Isuzu chassis technology is mature and complete services in the country, prices are relatively cheap. At present, the domestic arm mounted concrete pump truck chassis with the engine to reach Euro Ⅱ or above standard to meet the environmental requirements of large and medium-sized cities. 

 The arm-mounted concrete pump operations from time to time by the upper space restrictions require the top of the boom expand the minimum height of 4 jib folded generally use a single R or Z-shaped type. More than five boom due to space constraints, the folding type commonly used combination of RZ boom unfolding Shoulong, the applicability of mobility and flexibility enhancements
