The average fuel consumption of Sany SSR220 is 13.7L/h, and Sany SSR220 single roller leads the single roller into the era of full pressure and double drive. Cross-border integrated reducer+lightweight design, cost reduction 10%, the industry's first energy-saving technology, fuel consumption reduction of 30%. Strong driving force and good compactness. SSR220 roller has mechanical price and full hydraulic dual drive performance. Equipped with Sany Yitz 155kW engine, the front wheel distribution mass reaches14.6t, which is 33% higher than the mechanical compaction capacity of the same tonnage, and the climbing ability is as high as 50%. After compaction, the road surface is smooth, and there are no problems such as cracks, soil clinging and scratches at the beginning. Strong performance, equipped with Sany invention patent: energy-saving technology of vibratory roller, intelligent speed change of engine, and mechanical oil consumption lower than 15% year-on-year.
