- Page 34 Rubber tire roller Rubber tire roller Flexible and economical compaction Drive concept: efficient and reliable BOMAG pneumatic tired rollers BW 24 RH / BW 27 RH combine conventional compaction technology with a state-of-the-art hydrostatic drive. For this purpose the rear axle is replaced by two hydraulic motors. This is effi- cient and optimizes operating and maintenance costs.
