With the acceleration of the pace of economic construction in our country, many large-scale engineering construction projects have been launched one after another, and the demand for concrete machinery in the market is increasing rapidly. At the same time, the State has introduced a policy prohibiting the use of on-site agitated concrete in urban areas, making concrete pumps, such as concrete pump trucks, hot. These favorable external conditions provide a vast space for the development of concrete pump trucks. At present, although the sales volume of the concrete pump truck market is still relatively small, the technological content and the added value of the products are relatively high. The entire domestic market has been developing rapidly under the drive of domestic companies such as Sany and China United.
Rapid growth in demand, market expansion
Concrete machinery mainly refers to concrete pumps (pumping pumps, truck-mounted pumps), pump trucks, mixer trucks, and mixing stations. According to statistics from HC Construction Machinery Network, the market demand for these products is generally increasing with the use of commercial concrete. And increase.
In recent years, the continuous development of domestic infrastructure construction has driven the domestic commercial concrete industry to take off. The expansion of construction scale and scope has promoted the rapid development of construction machinery and related concrete conveying machinery, providing a larger market for concrete pump trucks. space. Concrete pump trucks are an important tool in the construction industry. With the rapid development of the domestic commercial concrete industry and the construction machinery leasing business, the expansion of construction scale and scope, and the development of the western region and the construction of cameras for the old industrial bases in the northeast have driven concrete transportation. With the rapid development of machinery, the market space for concrete pump trucks has also been further expanded. With the rapid development of the domestic commercial concrete industry and machinery leasing business, concrete pump trucks are increasingly used in industrial, civil construction, national defense construction, infrastructure construction, transportation and energy engineering construction, and promote the concrete pump market. The rapid development has formed a large market supply and demand space. At present, the use of concrete pump trucks in China is rapidly increasing. The pump truck manufacturers and production are increasing, and the product performance and quality are rapidly increasing. In the past two years, the market demand for concrete pump trucks has increased rapidly, with an increase of more than 100%. The number of users of concrete pump trucks in China has also increased significantly. The group users are mainly commodity concrete suppliers with an annual production capacity of over 300,000 m3, construction and construction units with relatively large scale in the industry, construction machinery rental enterprises with certain economic strength and operating scale, and construction and construction units from the original Separated equipment management departments, etc.; individual users are mainly individual mixing stations and individual machinery rental departments in developed coastal regions. There are currently more than 1,000 group users in the country.
Main domestic market of concrete pump trucks
At present, the domestic market for concrete pump trucks can be divided into two types. One is a developed region represented by Shanghai, Guangdong, and Beijing. These regions are more competitive and the market is stable. The second is the underdeveloped regions such as the Midwest. The regional market has just started and is in a rising stage. With the successful development of core technologies such as booms, especially with the industrialization of concrete pumping technology in recent years, the market share of China's pump trucks and national brands has finally surpassed foreign brands, changing from the past 10% to 90% led China's concrete pump market. Among them, Sany and Zoomlion's pump trucks accounted for more than half of the domestic market, becoming the first-line brand of domestic pump trucks and the world's leading long-arm racks and large-displacement pump truck manufacturers. In 2001, Zoomlion cooperated with Volvo to develop a new generation of intelligent concrete pump trucks, and quickly completed a series of hair growth, design and production with arm lengths of 37 to 56 meters. There are also Xu Zhong 52m concrete pump trucks and Sanyi 66m long arm pump trucks. At present, there are more than 10 concrete pump truck manufacturers in China, with an annual total production capacity of 600 vehicles, mainly in Dongfeng, Zoomlion, Sany Heavy Industry, Liaoning Heinuo, Anhui Xingma, Shanghai Push and Shandong Hong. Da Jian Gong Group and other enterprises account for 95% of the industry's total output. The trend of localization of concrete pump trucks has also been strengthened.
The gap with foreign advanced products is narrowing
The boom-type concrete pump trucks in China have developed rapidly in recent years. Although they are not as good as foreign ones in terms of product stability and technology, China’s products have obvious competitive advantages in terms of cost-effectiveness and after-sales services, and are more in line with Domestic actual construction situation. Among them, Zoomlion and Sany Heavy Industry have taken the lead in the development of boom-mounted concrete pump trucks. Zoomlion developed the "Concrete Pump Truck" standard and also developed a remote maintenance and positioning system for pump trucks. Sany Heavy Industry's concrete pump trucks are comparable to foreign famous brand products in terms of pumping pressure, pumping displacement, stability, and reliability. Its pumping machinery products have been sold to the Middle East, North Africa and South Asia. The performance level of other domestic pump truck products is also rapidly increasing.
New technology boosts the development of concrete pump trucks
(1) The chassis is diversified. At present, the boom-type concrete pump trucks in China are commonly used in Volvo, Mercedes-Benz and Isuzu chassis, and boom-mounted concrete pump trucks using domestic chassis are also on the market. With the maturity of the domestic boom type concrete pump truck market, the profit rate of the vehicle has been declining. In order to meet the different needs of users, the boom-mounted concrete pump truck adopting the domestic chassis and the imported chassis will occupy its own place in the market. .
(2) The hydraulic system develops towards integration. The hydraulic system is the core part of the concrete pump truck. The quality of the hydraulic system will directly affect the performance and efficiency of the host. The boom type concrete pump truck generally adopts the open system and constant power control, especially the large-flow pump. The open system has many advantages such as low oil temperature, high reliability and convenient maintenance. At the same time, full hydraulic control technology and computer control technology have made breakthrough progress. Full hydraulic control technology and computer control technology have also made breakthrough progress. For example, the full hydraulic commutation and computer closed-loop control technology of Sany products has been widely used.
(3) Energy conservation and environmental protection have become the development trend of pump trucks. Increasing the energy saving and environmental protection performance of concrete pump trucks has become a trend. Wind cooling has gradually replaced water cooling, and the emission standards for engines have also increased, mostly reaching Euro II or Euro III standards.
(4) Structures are more applicable. The boom type concrete pump truck is often limited by the upper space during operation, requiring the boom height to be the lowest at the time of boom deployment, and the boom frame folding below 4 knots generally adopts a single R or Z type. Due to space constraints, the boom frame is generally used in the RZ combination to achieve unfolding and folding of the boom. The applicability, maneuverability and flexibility are enhanced. Especially in the construction of tunnels and indoor operations, the efficiency is significantly improved. In previous years, the length of the domestic boom was mostly 37m, and there has been a growing trend in the past two years. In the future, concrete boom trucks with a longer boom will come to market. In addition, when the outrigger operation of the jib-type concrete pump truck is limited by the space of the venue, especially the large jib concrete pump truck, the design of the outrigger-type concrete pump truck legs presents individualized and diversified features.
(5) The boom technology has improved. Boom technology is a key technology for concrete pump trucks. It used to be controlled by manufacturing companies in a few developed countries such as Germany and the United States. In recent years, China's boom-type concrete pump trucks have developed rapidly. In terms of product stability and technology, although not as good as foreign products, they have made considerable progress and are more in line with domestic actual construction conditions.
(6) The concrete output is larger. The central pumping system has a higher pressure and a larger delivery volume, which will become the development trend of the central pumping system for the domestic boom type concrete pump trucks in the future. As the boom of the jib crane concrete pump truck is getting higher and higher, the models are getting bigger and bigger. The bore diameter of the delivery cylinder is also getting bigger and bigger. At the same time, due to the increasing requirements of the project schedule, the pump displacement is required to be 80. With more and more projects of ~120m3/h, large displacement will become the development direction of arm-type concrete pump trucks in the future. In addition, the pumping pressure is getting higher and higher. The pressure of concrete exports has now reached 22 MPa, and there is a tendency to continue to increase.
(7) The control system has more functions. The electrical system of the boom-type concrete pump truck has developed rapidly in the past two years. The electronic control system for concrete pump trucks produced by domestic manufacturers is developed from the traditional PLC control to the dedicated controller and computer intelligent control. Through the touch screen, human-machine dialogue can be realized. Various operating parameters can be stored and displayed to achieve automatic monitoring of the vehicle. Once the whole machine operation fails, in addition to the alarm prompts, relevant parameters can be called for fault analysis and diagnosis. At the same time, the application of the boom control system technology can achieve the same level of amplitude and intelligent pouring of the boom.
In addition to the rapid development of equipment design and manufacturing, the use and maintenance of equipment has also been correspondingly improved. The majority of equipment users are becoming more familiar with the principles, structure, operation, and routine maintenance of concrete pump trucks. Make the equipment more comfortable to use in the construction process, and play an increasingly important role. With the rapid development of China's urban construction and the continuous expansion of the scale of infrastructure construction such as transportation and water conservancy, the application of commercial concrete has become increasingly widespread, and the demand of users for concrete pump trucks will be even more prosperous. It can be foreseen that concrete pump trucks will be favored by more and more users, and domestic pump trucks will continue to show rapid development.
