YZ20 and YZ18 type total-hydraulic vibratory road rollers’ brief introduction
YZ20 and YZ18 type road rollers are HONGDA’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. They have the following technical features:
- Key parts all adopt first-class product of international famous brand to ensure no less reliability than world top brand road rollers；
- Tail gas exhaustion up to EUROPEAN Ⅱ standard is popular with enviromental protection customers；
- The machines’ overall weight is above 20.3(18.6) tons and have an exciting force of 380 kN,which produce an outstanding compacting effect；
- Double frequency and peak-to-peak amplitude can match with paving layers of various characters and various thickness；
- A scientific mass proportioning of front and rear axles can ensure an excellent compacting function as well as proper driving property on all kinds of road surfaces；
- Professional outline industrial moulding design can give customers a pleasant feeling with original appearance and superb form；
- An roomy and bright cab with air-conditioner, acoustics, adequate forward and backward visibility, comfortable chair,operating mechanism in line with man-machine engineering,and good shock reducing effect can afford a nice and easy working enviroment for drivers；
- Covering parts which can be opened wholy adopt pneumatic boosting and make daily maintenance easily available. The average maintaining time per week won’t exceed 30 minutes；
- An adequate safety protection equipment can guarantee driver’s personal safety.
