(YZ20, YZ18 and YZC12 Types of All-hydraulic Vibratory Road Rollers)
The YZ20, YZ18 and YZC12 types of road rollers are all-hydraulic vibratory rollers independently designed and developed by HONGDA Group. The machines have such advantages as strong vibratory force, high static line pressure, double frequency and double amplitude, full drive and high reliability that they can be used for various engineering projects and will achieve most satisfactory compacting effects on pavement layers with different characters and different thicknesses, for example, in road, railway, airport, harbor and water conservancy construction sites. Their main technical features are as follows:
- All the key parts are first-class products by world-famous manufacturers, which make the machine as reliable as world-famous road rollers.
- The tail-gas exhaustion is up to the EUROPEAN standard and is popular with environment-friendly customers.
- With total weights of over 20.3 tons and 18.6 tons respectively, the machines produce an exciting force of 380 KN and have outstanding compacting effects.
- The double-frequency and double-amplitude design applies to pavement layers of different materials and different thicknesses.
- The scientific mass proportioning of the front and rear axles ensures not only excellent compacting effects but also good driving performance on all kinds of road surfaces.
- The professionally-designed original appearance can give customers a pleasant feeling.
- The roomy and bright cab with air-conditioning and acoustic equipment has adequate forward and backward visibility, comfortable seat, operating mechanism in line with human engineering and good vibration reduction effect, which creates a nice and comfortable working environment for the driver.
- The covering parts that can be opened as a whole adopt the pneumatic boosting technology, which makes daily maintenance easy and simple. The average maintenance time per week wont exceed 30 minutes.
- The perfect safety equipment can guarantee the drivers personal safety.
