The pivot-steer rollers unique crab-walking capability allows the machine to distribute weight over a wider area, beneficial for compacting thin layers and sensitive surfaces. The crabwalk can be combined with any of the four steering modes, allowing the operator to compact sensitive mixes without difficulty and large amounts of asphalt quickly. When steering the rollers around a bend while in crabwalk mode, BOMAG’s adaptable steering control means the operator doesn’t need to worry about manual corrections. The crabwalk feature also increases safety and stability when working along edges or along angled slopes.
Both the BW 154 and BW 174 rollers feature front and rear split drums. The design reduces shearing stress when making tight turns on asphalt, which minimizes the surface’s ability to form cracks.
Driving comfort is optimized with the foot-operated seat. The seat can be rotated up to 270 degrees and the armrest projects out of the window when shifted left or right to the extreme, offering the operator excellent vision from anywhere in the cab.
