Ride On Road Roller mainly used for compacting soil, trench foundation, large excitation force and high compacting efficiency.
It is ideal for rolling sand, semi-cohesive and cohesive soil, roadbed stable soil and asphalt concrete pavement.
It can also be used for the compaction and leveling of asphalt surface operations, and can be used to compact sand, gravel, soil and asphalt. All can also be said that such a Road Roller is equivalent to the combination of a single wheel and a double wheel.
For a full hydraulic dual-drive vibratory roller, the steel wheel is involved in both compaction and walking drive, so the load of the steel wheel can be designed to be large, generally accounting for 70% of the weight of the whole machine. it is good. Vibration is the use of high-frequency vibration generated by a vibrator fixed on an object of a certain mass to be transmitted to the pressed material, causing it to vibrate close to its own natural vibration frequency. As the particles approach and the density increases, the material is compacted. Vibration, low surface stress, short process time, large loading frequency, can be widely used for materials with low viscosity, such as sand, cement concrete mixture.
