The Bomag BW 177/179 DH/PDH-4 single drum roller is a versatile and reliable compaction machine designed for a wide range of applications, including asphalt and gravel paving, trench backfilling, and soil stabilization. The BW 177 and BW 179 models differ primarily in their operating weight and drum width, with the BW 177 offering a smaller footprint and the BW 179 providing increased compaction capacity. The DH (Diesel Hydraulic) designation indicates that the machine is powered by a diesel engine and uses hydraulics to drive the drum. The PDH (Pneumatic Diesel Hydraulic) designation, on the other hand, signals the addition of a pneumatic tire-mounted roller, allowing for dual compaction methods. This combination caters to various surface conditions and ensures optimal compaction results across different projects. Bomag's BW 177/179 DH/PDH-4 rollers are known for their robust construction, featuring durable steel frames and heavy-duty components.

The compact size and maneuverability of the machine make it ideal for working in tight spaces and navigating challenging terrain. The operator's cab offers excellent visibility and ergonomic controls, enhancing operator comfort and productivity. The inclusion of a pneumatic tire-mounted roller in the PDH models further strengthens versatility, enabling the machine to efficiently compact both granular and cohesive materials. Bomag's BW 177/179 DH/PDH-4 single drum rollers represent a powerful and versatile solution for various compaction tasks, delivering high-quality results and contributing to project success.
