The RS7120 is an SDLG single-drum vibratory roller driven by a Weichai common-rail, turbocharged and intercooled engine with three-stage fuel filtration for strong, fuel-efficient power. Its through-axis vibrating drum maintains a stable, consistent amplitude for reliable compaction, while the articulated frame, tight turning radius, and premium drive axle deliver smooth, durable performance.

The upgraded H-series cab offers wide visibility, rocker switches, and a clear digital instrument panel, and centralized filters, a fuse box, and a one-key electric hood make routine maintenance quick and simple.
