The XSM218/220 are heavy-duty self-propelled vibratory rollers designed for compaction on base courses. Sub-base courses and fills. Typical areas of applications are high-grade highways, airfields, seaports, dams and industrial construction sites. The XSM218/220 has the following features in its structure and performance: Full hydraulic steering system makes it possible, with the articulated frame, to achieve easy and flexible steering. Electrically controlled power-shift transmission with 3 speeds forward and 3 speeds reverse. The vibratory system comes with a closed-loop hydraulic circuit comprising internationally sourced hydraulic pump and motors to ensure high working pressure, high efficiency and long service. Three-level shock-absorption, together with sealed and sound deadened cab offers safe and comfortable operator environment.
