China's maintenance machinery development trend

The introduction of electromechanical-hydraulic integration and electronic monitoring CNC technology The main features of road surface construction and maintenance since 2000 are the pursuit of high efficiency, high quality, and high efficiency. Therefore, construction and maintenance machinery are required to have good operability, high degree of automation, and large operating capacity. Fast, economical, and less polluting.
Its main development trends are:
1. Learn and introduce foreign advanced electromechanical and hydraulic integration technologies and electronic monitoring technologies to develop energy-saving, high-efficiency, low-noise, low-pollution and high-degree-of-automation maintenance machinery; research and develop fault automatic monitoring systems to improve the safety of maintenance machinery , comfort and ease of operation.
2. In order to increase the use efficiency of machinery and meet the needs of conservation operations, it should develop in the direction of high-power and multi-purpose to meet the requirements of safe and fast operation of expressways; at the same time, develop simple multifunctional maintenance machinery to meet the general road surface. Conservation needs, such as modification on tractors, loaders, and car chassis. Products developed in this way have less investment, short cycle times, and relatively inexpensive prices.
3. Some leading plants have advanced into foreign advanced CNC processing equipment and technology to improve the manufacturing technology and process level, product quality, reliability and service life of maintenance machinery.
Development of road testing equipment, special chassis, recycling equipment and marking machines
1. Road conditions diagnosis and testing equipment urgently needed development. Establish a computer-based highway maintenance management system and establish a database including various road information to make a correct assessment of the current status and performance of the road surface, and predict the degree of road degradation in the future so as to formulate correct conservation measures and plans. , is the consistent practice of all countries in the world.
China's highways, especially high-grade roads, must also take this route. To this end, it must be equipped with a high degree of automation of road conditions diagnostic testing equipment, using these devices to quickly complete the data collection. Need to develop a multi-energy testing equipment.
2. There is an urgent need for the development of a special chassis for multipurpose vehicles. It is necessary to develop and produce a special chassis for comprehensive maintenance vehicles equipped with mechanical, hydraulic, electric power output interfaces, work device quick-change mechanisms, and travel capabilities of 0.1 to 80 km/h.
With such a chassis, road maintenance workers and machine manufacturers can provide convenient conditions for the development of maintenance machinery. This is very beneficial to the realization of mechanized maintenance of high-grade highways in China.
3. There is a clear demand for asphalt pavement recycling equipment.
In Japan, half of asphalt concrete mixing equipment is recycled equipment; in the United States and Europe, on-site asphalt pavement regeneration recombiners similar to “Road Repair King” have been developed. In the future, there will be obvious demand for asphalt mixture recycling equipment, emulsified asphalt normal temperature mixing technology and equipment, and asphalt pavement on-site regeneration and reloading machines.
4. There will be obvious demand for large road marking lines. Road marking is an important part of the highway. Statistics from foreign countries show that the marking can increase the transportation efficiency by 30% and the correlation with traffic accidents is 70%. The annual growth rate of China’s auto ownership is 10 times that of roads, so perfecting the various safety facilities on highways has become a top priority. Road markings bear the brunt of this. As a result, the demand for large-scale automated striping machines has increased significantly since 2000, especially for large-scale heated and hot-melt paints.
Demand for several major conservation vehicles is 5 to 150 units. The 10 to 20 years after 2000 is a critical and important historical period in China's road construction. It is characterized by urgent social needs, clear targets, and adequate funding. It must be China. The golden stage of highway development. The state decided to accelerate the construction of the "five vertical and seven horizontal" highways by the end of the "Ninth Five-Year Plan" period to 2010.
According to this request, by 2010, the "five longitudinal and seven horizontal" main line will be basically completed. This will provide broad development prospects and market space for China's road maintenance machinery, especially high-grade highway maintenance machinery. According to the predictions of experts and leaders of the domestic transportation highway industry and the analysis of the configuration of existing high-grade highway maintenance highway equipment, it is estimated that in the next 10 to 20 years, the domestic market demand for several major maintenance machinery will be: 1. Milling The cold planer with a width of 1 to 2 meters and special equipment for road milling require an annual demand of approximately 120 to 150 units, of which the annual demand for large-scale milling machines with a milling width of two meters is 10 to 20. 2. Versatile comprehensive maintenance vehicles that can perform cleaning, weeding, snow throwing, watering, and road surface cleaning, as well as a variety of multifunctional comprehensive maintenance vehicles that can complete road surface impact crushing, asphalt heating and insulation, asphalt spraying, road rolling, and other road repair operations. The annual demand is 120 to 150 units. Some users of highway systems are suggesting the development of small multi-purpose pavement maintenance machinery similar to the Bobcat multi-function machine. It has five functions, including hydraulic crushing, road surface (cement) planing, cutting, shoveling, and compaction. The price ranges from 150,000 yuan/table to 200,000 yuan/station, which can be used for high-grade road maintenance as well as for Ordinary roads, airports and other pavement maintenance.
3. The annual demand of the asphalt mixture regenerating equipment, the thawing asphalt normal temperature mixing equipment, and the asphalt pavement in-situ regenerator and other hot and cold reclaiming machines is 20 to 30 sets. Users believe that foreign "road repair king" asphalt pavement reclaimer is very advanced, very good, but the specifications are too large, too expensive, the use of high costs, after the purchase of the site is serious, it is recommended to develop a similar small and medium-sized machine.
4. Slurry sealer, annual demand plus 10 to 15.
5. Large-scale wreckers with a lifting capacity of over 20 tons. The annual demand is about 10 sets.
6. Large vehicle-mounted marking line marking machine, the annual demand is 5 to 10 sets.
7. The large-scale high-speed sweeper has an annual demand of 15 to 20.
