The Bomag BW211 — the SA standard for granular compaction
If you are building a road, an embankment or a bulk fill in South Africa, the Bomag BW211 is almost certainly involved. Widely supported, fuel-efficient, and with strong resale, it's the default choice at the 10-ton single-drum class.
D-40 vs D-50 vs PD
- BW211D-40 — the standard spec, 27 Hz / 32 Hz vibration, suits most SA roadworks.
- BW211D-50 — higher frequency and centrifugal force, better on deep lifts of granular material.
- BW211PD — padfoot drum, for cohesive soils (clay-heavy fills).
Buying used
Check the drum for wear (a worn drum reduces compaction quality and is a R 120k – R 220k replacement), the vibration bearings (listen for rumble at low speed), and the articulation joint. A well-serviced BW211 with 3 000 – 5 000 hours in the R 750k – R 1.1m band is a strong buy for any civils fleet.
