Fully Hydraulic 20 ton Construction Road Roller SR20-3 Vibrating Ground Road Compactor
Product Description of 20 ton Construction Road Roller SR20-3 Vibrating Ground Road Compactor
1) Sprinkler system
The 1100L tank greatly extends the working time and has two injection and two water outlets.
2) Vibration system
● Dual frequency/double amplitude can be spread in thin layer compaction in high frequency operations, improve production capacity.
● The vibration system of SR14D has two frequencies of 51Hz and 67Hz, providing high frequency vibration for thin layer compaction and large amplitude vibration for high performance asphalt mixture compaction.
Shantui’s high grade and high standard choice of critical parts of the roller (including engine, drive parts, and hydraulic parts) guarantees the performance and reliability of the product. The professional design on the static linear pressure, vibration
amplitude, and vibration frequency and the appropriate speed and gradeability performance realize maximum working efficiency while providing high compacting performance.Finally, it has the extra-added touch of having a very attractive design flow to its outward appearance.
