(YZ20, YZ18 and YZC12Types of All-hydraulic Vibratory Road Rollers)
The YZ20, YZ18 and YZC12types 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:
l All the key parts are first-class products by world-famous
manufacturers, which make the machine as reliable as world-famous
l The tail-gas exhaustion is up to the EUROPEAN ��/span> standard and is popular with environment-friendly customers.
l 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.
l The double-frequency and double-amplitude design applies to
pavement layers of different materials and different thicknesses.
l 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.
l The professionally-designed original appearance can give customers
a pleasant feeling.
l 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.
l 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 won’t exceed 30
l The perfect safety equipment can guarantee the driver’s personal
