The new pet of construction machinery -- walking type small roller

With the rapid development, the construction machinery has put forward a variety of requirements, and the construction machinery industry for its own better development is also constantly updated with the times of good equipment.

Review of domestic pavement construction machinery is a relatively late start, relatively young industry. Although in recent years with the development of science and technology of engineering machinery and mechanical compaction effectively developed, but foreign companies in early twentieth Century 50, 60s has already begun, but at the beginning of 60s 70s at the end of the past 20 years, the development speed is very slow, when the compaction machinery foreign manufacturing enterprise R & D is mainly by two and three wheel rolling equipment for the construction of low the highway (including gravel) and small machine maintenance, the roller process is relatively slow.

The real development of construction machinery and equipment in China began to form in the late 1980s. Today, after more than 30 years of development, China's construction machinery and equipment has become an important part of China's engineering construction, with the expansion of China's FTA, more foreign companies began to introduce made in China. From the analysis of past production, engineering machinery and several main types of annual output than the beginning of 1980s has turned over several times, such as frame type leveling machine equipment, the annual output has reached more than 10000 units, about 30000 units, small milling roller about 13000 units, about 8000 units of hydraulic milling machine.

The development process of Chinese compaction machine is very long, from the middle of twentieth Century before and after the imitation spawned an entire industry, so as to realize the first reform from scratch, in late 80s, the introduction of domestic roller technology, a China hydraulic vibration roller drive to the river, after nearly 10 years of development has not only been a lot the degree of improvement in the series and varieties of products, ensure product performance and reliability. The following is for everyone to analyze why the small road roller will be green by the highway maintenance department.

Second, the small roller adopts the new design concept, can play a rolling effect in a small area, and the effect is obvious.

Fourth, the current domestic highway maintenance work mainly depends on the manpower, and the small roller equipment appears to facilitate the operation of construction personnel, and largely saves manpower and material resources.

Due to the large size and heavy equipment of the traditional roller, it can not play the role of rolling and compaction in some small areas.

Compared with small roller, large roller is more convenient than roller in the process of transportation, handling, driving and operation.

The highway suffers from natural erosion and weathering all the year round, such as rainstorm, wind sand, sunlight, flood, snow and ice, abrasion and impact of wheel. The damage of large or small degree and wear, is not in front of a small fee force roller, in the use of small roller can be timely, simple, rapid repair of narrow region, thereby prolonging the service life of the road, played a pivotal importance
