YZ20 and YZ18 type total-hydraulic vibratory road rollers' brief introduction
YZ20 and YZ18 type road rollers are our's independently designed and developed superheavy total-hydraulic vibratory rollers on its comparative absorption of advanced technical properties of domestic and foreign rollers. The machines have such advantages as strong exciting force, high static line pressure, double frequency and peak-to-peak amplitude, full-driving, and high reliability, etc. They can widely apply to compacting work of such all kinds of engineering construction as road, railway, airport, harbour, water conservancy building site, etc. With best compacting effect on pavement layers of various characters and various thickness.
