Road roller technology development

- Mar 01, 2019-

In the 1970s, with the development of hydrostatic transmission technology, hydraulic control technology and computer technology, the research on compaction technology and compaction equipment has made great progress. First of all, hydrostatic transmission is applied to the compaction machine. Through the control of the flow rate of the hydraulic system, the rotation speed of the motor can be easily changed, and the vibration frequency of the roller is continuously adjusted, thereby simplifying the complicated transmission system. During this period, the research of vibratory roller mainly focused on the optimization of vibration roller parameters, and gradually realized the stepless continuous adjustment of vibration frequency and vibration amplitude, and improved the compaction effect.
