Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a road compacting device. Background Art

[0002] As an important construction machinery, the background and development of road rollers are closely related to the needs of construction projects and technological progress. The most basic principle of road rollers is the compaction principle, which has been applied in stone rollers in ancient China. In modern times, the development of road rollers has gone through a process from simple to complex, from inefficient to efficient. Today, road rollers have developed into many types, such as static rollers, vibratory rollers and impact rollers, each of which has its specific uses and advantages.
