XCMG road roller XS303
XS262/XS302 is the super heavy-duty hydraulic drive vibratory roller with the largest tonnage in China. Representing XCMG's new generation of super heavy-duty vibratory rollers, the machine takes a lead in operation, propulsion, compaction, reliability and serviceability in the industry, becoming an optimal compacting equipment in the constructions of high-grad roads, airports, ports, dams, and construction sites. It adopts large power engine and anti-slip hydraulic drive system, which can meet various construction requirements better.
•ROPS driving cab is equipped with an air conditioner, radio and suspended chair. It has a bigger space and broad view inside.
•Unique cylindrical drum structure features high rigidity and intensity. Short cylindrical bearing with high limited rotation speed provides high load - carrying capacity. The symmetrical arrangement of the right and left vibration chambers avoids the polarization of the vibratory drums.
•The simple and easy lubrication mode ensures an extremely low failure rate of the lubricating system.
•XCMG is the first manufacturer to adopt the central engine for effortless maintenance.
•According to the ergonomics theory, all meters, indicators and buttons are centered on the operation panel. The throttle handle and FWD/REV handle are put on the right side to improve the sense of comfort.
•The failure diagnosis screen with alarms can avoid any unnecessary downtime.
•The key components are provided by international suppliers (hydraulic pump, motor, drive axle, vibratory bearing and rotating alarm lamp); it also has several engine models for selection to meet different working conditions and customer's needs.
Leading compacting performance
•The unique hydraulic driving system design and heavy vibratory wheel weight make the XCMG's roller highly advanced in compaction ability.
•Heavy loaded drive axle and nonskid differential mechanism can furthest transfer the output power as well as the tractive force of engines.
•The aural and visual alarm device can timely provide the maintenance message to avoid the machine faults and to shorten the down time. The self-opening tilt-rearward engine shield makes the engine and hydraulic pump easy to access to.
