XCMG XS120 Vibratory Roller is the medium self-propelled single-drum vibratory roller, which is mainly suited for com- paction during the engineering construction of high-class highways airports, harbours, dams and industrial yards. Also lends itself to use on the large-scale base course, sub-base and embankment fill compaction. The machine has original imported high-power engine and special hydraulic driving system,which can make the machine work widdy at any envi- ronmental areas to satisfy different perfermance requirement. XCMG XS120 Vibratory Roller takes its main combonents and system according to international style.lt has following described advantages in its structure and performance:Two-level infinitely speeding of closed hydraulic driving system, double frequency and double amplitude,density on line suspecting,wholly closed air-conditioned driving system,double frequency and double amplitude,density on line suspecting,wholly closed air-conditioned driving car, ROPS sys-tem certitied in term of safety.the operating system which fulfills the principle of human engineering,suspensional seat,hydraulic articulated steering and configuration of stream line.
