The development trend of domestic compaction machi

In the next few years, the development trend of domestic compaction machinery

Guide: industry insiders believe that with the further upgrading of domestic highway construction, domestic compaction machinery will gradually eliminate a number of backward models and instead develop models with world advanced technology. Light compaction equipment frog rammer is a simple compaction construction machinery, with a huge market share, but the work efficiency is very low

insiders believe that with the further upgrading of domestic highway construction, domestic compaction machinery will gradually eliminate a number of backward models and turn to the development of models with world advanced technology

light compaction equipment frog rammer is a simple compaction construction machine with a huge market share, but its work efficiency is very low and its safety is poor. Generally, it can only carry out the leveling and preliminary compaction of small-area thin pavements. With the increasingly mature technology of vibratory plate rammer and vibratory impact rammer, it will be popularized and applied in the near future, so that the frog rammer will really withdraw from the stage of use

at present, the static action smooth wheel roller still accounts for about a quarter of the market of compaction machinery in China, while the high-grade full hydraulic model is still in the planning and development stage. It is expected that under the general trend of slow decline or fluctuation of the total volume, individual models such as 3y21 will still be in the rising period in the next three years or so; The 3y10, 3y15 and other models may rise again in Southeast Asia. However, after China's accession to the WTO, the static action smooth wheel roller has accelerated the decline of 10 large plastic markets after a relatively short stability period around the new year, until it is basically eliminated

the small double drum tandem vibratory roller has obvious advantages such as advanced technical performance, high operation efficiency, low energy consumption and simple operation. It is the most scientific and economical model to replace most static action smooth wheel rollers. For example, xd25 (yzc2.5), xd40 (yzc4) and other models developed by Xuzhou Construction Machinery Factory of XCMG group will become the first choice for small-scale engineering compaction. At the same time, the high-grade full hydraulic static action smooth wheel roller model will be developed in some varieties, and eventually become a reserved model of complementary nature

tire roller is also a static action roller. Due to the unique flexible compaction effect of pneumatic tires, it has become an essential machine to improve the compaction quality of pavement in the construction of high-grade roads, whether it is foundation compaction or surface compaction. Therefore, the tire roller will maintain a continuous growth momentum, and there is a trend to shift to large tonnage. At present, when we do experiments, the vast majority of domestic tire rollers are mechanically driven, and the operation is cumbersome and laborious; Full hydraulic transmission is the direction of technology development and market demand, and has begun to sprout; The hydraulic transmission model is between the two and may become a temporary transitional product

although the current market is keen on large tonnage, if it is not more than 18t, it is not allowed to go on the highway. These are based on the current situation of strict construction progress and less strict construction quality. In the long run, t will eventually be the main model

the proportion of full hydraulic double drum vibratory roller in the total amount of roller is a reflection of the development of compaction machinery and the quality level of road construction in a country. This model has always been a weak link in China, and the proportion is less than 10% (more than 25% in European and American countries). Therefore, it will show a rapid growth momentum for a long time in the future, and T will be the main model. This can not only fully ensure the compaction quality, but also give full play to the maximum working efficiency of the machine and the coordination of supporting operations with other equipment

on the premise of improving the operating comfort, the mechanically driven single drum vibratory roller will keep up with the full hydraulic single drum vibratory roller in terms of self-made and supporting parts and modeling design, continue to maintain a relatively vigorous vitality, and will take t as the main model. It is expected that it will continue to rise in the next three years or so, and after a short stabilization period (about years), it will decline all the way to build an open lightweight R & D platform until it is eliminated

considering the gap between domestic users' requirements for product performance and purchasing power, it is not impossible for some intermediate products (such as power shift gearbox plus drive axle model and single drive full hydraulic transmission model) to emerge as a new force. Domestic enterprises can easily do well in a short time by using flexible development, production and sales systems
