What is a towed vibratory roller? What is a towed impact roller?

Trilateral towed impact roller Both towed impact roller and towed vibratory roller belong to towed roller. In short, they are engineering compaction machinery that does not have walking function and needs to work under the drive of traction machinery. Quadrilateral drag impact roller Among them, the impact roller of the towed impact roller is non-circular polygonal structure, according to the different shape structure, divided into three-sided impact roller, four-sided single-wheel impact roller and five-sided two-wheel impact roller. Self-propelled pentagonal impact roller The working principle of the towed impact roller is the same as that of the self-propelled impact roller. The impact force of the three-sided impact roller is relatively large, which focuses on the impact compaction of the roadbed. The force of the four-sided impact roller is moderate. Both of them can be used for compaction of the roadbed and pavement crushing. Moreover, the four-sided impact compactor is designed with a single wheel, and the pavement is relatively narrow, the impact force of the pentagonal impact compaction wheel is relatively weak compared with the three-sided impact compaction wheel, which is mostly used for road crushing and impact compaction of silty soil and sandy soil. self-propelled vibratory roller The working principle of towed vibratory roller is the same as that of self-propelled vibratory roller. It also relies on self-weight and exciting force to force the compacted material to do vertical forced vibration, which sharply reduces the internal friction between soil particles and achieves the purpose of compacting soil. The size of the exciting force can be adjusted as needed. towed vibratory roller Towed vibratory rollers are rollers with single steel wheel structure. According to different weight and different output power, it is divided into light towed vibratory roller and heavy towed vibratory roller. Generally speaking, if the weight of the equipment is less than 10 tons, it can be defined as a light towed roller. Due to different requirements of construction specifications, it is widely used abroad. light towed vibratory roller Equipment with a weight of more than 14 tons is called heavy towed roller, which is widely used in China. Heavy towed vibratory roller is an indispensable compaction machinery in the foundation construction of highways, railways, dams, airports and other large-scale projects, especially for large-scale filling construction, when the compaction degree is required to be more than 95%, it shows the necessity and efficiency of this kind of machinery. Heavy towed vibratory roller Light towed vibratory roller and heavy towed vibratory roller are used in different ranges, and different towed rolling wheel quality or exciting force can be selected according to different compaction thickness and materials. In addition, due to the small weight of the vibrating wheel, the power output of the light towed vibratory roller is mostly borrowed from the power output of the tractor, while the heavy towed vibratory roller is mostly equipped with high-power power output.

Polishing Machine Market Demand Analysis Polishing Machine Industry Market Status Analysis

Polishing machines, also known as grinders, are often used for mechanical grinding, polishing and waxing. The motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at high speed. Due to the joint action of the polishing disc and polishing agent and friction with the surface to be polished, the purpose of removing paint surface pollution, oxide layer and shallow marks can be achieved. The rotating speed of the polishing disc is generally 1500-3000 r/min, mostly stepless speed change, which can be adjusted at any time during construction. Polishing machine market demand According to statistics, nearly 1/3 of China's magnetic polishing machines are imported. Some are far from international standards. Of course, some can be compared with the international level. Based on this, we should also be able to have a general understanding of the current situation of my country's magnetic polishing machine machinery industry. According to the China Research Institute's "2022-2027 China Polishing Machine Industry Supply and Demand Trends and Investment Risk Research Report" analysis: At present, the goods of the domestic magnetic polishing machine company are still in the middle and low range, so the progressive commodity quotation can only hedge the loss caused by the cost in the short term, rather than a long-term solution. Analysis of the broken organization in recent years will find that processing bases, grinding machines, special processing magnetic hair remover and carbohydrate imports account for more than 1/5 of the total amount of metal processing magnetic hair remover, large magnetic grinding machine magnetic polishing machine is still a hot demand. China's magnetic polishing machine magnetic polishing machine industry recently showed that the demand for CNC magnetic polishing machine magnetic polishing machine began to increase significantly. In practice, China's magnetic grinding machine magnetic polishing machine profession has done a lot of work in independent innovation and development. In terms of commodity information quality and performance, it is now gradually approaching the international level. Analysis of Polishing Machine Market Development Status Due to the variety of polishing machines, the storage capacity, software strength and financial resources of enterprises are very important, so many enterprises that produce polishing machines choose to produce several types of products. Moreover, the market competition of consumables is great now. There are hundreds of enterprises in China, mainly small and medium-sized enterprises. However, the market is shrinking and the inventory pressure of enterprises is great. Many companies that produce consumables are trying to reduce costs. At the same time, they are also focusing on market segmentation and making their products more professional, otherwise they will be eliminated. With the substantial increase in business in China, the healthy and orderly development of the second mobile phone market has become the key to the development of China's construction machinery industry. The International Magnetic Polishing Machine Commerce Bureau faces six major challenges in advance, such as disorderly rules, single business form, backward management mechanism of the second mobile phone operating company, gray trading becoming a tributary of the market, shortage of skilled personnel, lack of technical support for enterprise transformation and upgrading, and insufficient cognitive level. A small number of users in the purchase of second-hand equipment when the lack of identification of talent, sometimes appear shoddy product appearance. Customers found that the mechanical performance was greatly reduced after purchase, and the after-sales service was not perfect. In the event of a defect, maintenance costs and spare parts procurement costs are high. Industry insiders believe that for an upward magnetic polishing machine market, it is impossible to have laws and regulations alone. There should also be a relatively complete quality assurance organization and employees that can specify the standards written on paper. Action standards to develop.

Problems of Highway Maintenance Machinery

Problems of Highway Maintenance Machinery After years of large-scale construction, China's highway network has been basically formed, is about to enter a high tide of highway maintenance and repair. At the same time, the increasingly heavy traffic pressure puts forward higher requirements for the efficiency and quality of highway maintenance. These favorable factors will promote the development of highway maintenance machinery, and the concept of long-term "reconstruction and light maintenance" has led to the backward level of highway maintenance mechanization in China, so the future development space is huge and the market prospect is broad. Although the road maintenance machinery industry has made great progress, but the existing problems are also prominent, especially in the era of road maintenance, and the contradiction between the market demand is increasing. Specifically, the road maintenance machinery industry mainly has the following three major problems. 1, the industry foundation is weak, insufficient research and development. China's highway construction started late, the research on highway maintenance technology is not enough attention, most of the existing maintenance technology is introduced from abroad in recent years, therefore, the industry as a whole the original innovation ability is insufficient, advanced maintenance equipment is still mostly supplied by foreign manufacturers. 2. The industry has a high technical threshold, a long product promotion cycle, and the products also have the characteristics of multi-variety, small batch and customized production. Therefore, some large domestic construction machinery companies with research and development capabilities are currently unwilling to intervene. This also leads to the domestic enterprises engaged in the industry is generally small, research and development capacity and investment is insufficient, compared with similar foreign enterprises in product reliability and advanced there is still a gap, some of the technology and products in the country is still in the blank. 3, the industry standard system is not perfect. The standard system in the industry is not yet sound and perfect, and the basic standards that have a guiding role for the entire industry are still relatively scarce, which is not conducive to the rapid and healthy development of the industry.
