The RS7220H is a heavy-duty SDLG single-drum vibratory road roller that pairs a Weichai six-cylinder engine, backed by easy parts availability, with Danfoss motors for both vibration and travel.

A large 75 ml/r vibrating motor produces high excitation force (420/295 kN) with fast response, and travel speeds of 3.9-10.7 km/h keep compaction work productive. Independent split vibration mechanisms at each end distribute eccentric force evenly, and four-bearing support adds rigidity, lower oil temperature, and reliability. Centralized filters and fuse box, along with a wide-opening electric hood, keep servicing quick and convenient.
