The HW20-3 is a super heavy class roller that is a self-propelled, fully hydraulic, vibratory roller.
The roller can compact various building and road-building materials by using its dead weight and the exciting force, for good compaction effect, deep compaction and high efficiency.
The SR20-3 model is mainly applicable to the compaction of base layers, sub-base layesr and fills of various non-viscous materials, such as gravel, crushed stone, sand and gravel mixture, sandy soil and rock.
