About · Bomag BW174Overview
The Bomag BW174 is a single-drum vibratory soil compactor in the approximate 9,500 kg operating weight class, developing 100 hp of engine power. It belongs to the mid-range segment of soil compaction equipment, positioned between light walk-behind and heavy tandem or pneumatic-tyre machines. Machines in this class are purpose-built for compacting cohesive and mixed soils on infrastructure and earthworks sites. The BW174 is a widely recognised model within the Bomag range, a manufacturer with a long-standing footprint in European compaction markets.
Typical applicationsWhere this machine is used
Soil compactors of this weight and power class are typically deployed on road subbase preparation, earthfill compaction for embankments, trench backfill operations, and general civil engineering groundworks. The 9,500 kg operating weight provides sufficient static linear load for effective compaction of cohesive soils without excessive machine cost or transport complexity. This class of machine is also used on landfill cell construction and large-scale site preparation where output and manoeuvrability must be balanced.
Used-market inspectionWhat to check before buying
Before purchasing a used soil compactor in this class, inspect the drum shell for cracks, flat spots, and wear to the scraper blades, as drum integrity is central to compaction performance. Check the condition of the vibration bearing and listen for abnormal noise during operation in both amplitude settings. Examine the articulation joint and oscillation bearings for play, as these are high-stress components on any articulated single-drum machine. Review engine oil and coolant condition, look for signs of overheating or neglect in service records, and verify that all safety systems including the rollover protection structure are intact. Hydraulic hoses and fittings should be inspected for weeping or chafing, particularly around the drum drive circuit. A full service history substantiating regular maintenance intervals is the single most reliable indicator of a machine's true condition relative to its recorded hours.
Current marketPrice position
The Bomag BW174 is cross-shopped directly against the Hamm DV90 and the Hamm H11i, both of which compete in the same weight and power bracket for soil compaction duties. Buyers comparing these models typically evaluate differences in drum width, vibration system configuration, and cab specification, as well as the availability of brand-specific service networks in their operating region. Within the BW174 segment itself, price positioning is driven primarily by accumulated working hours, overall mechanical condition, and whether the machine is fitted with optional equipment such as edge-cutting drums, padfoot shell kits, or an enclosed operator cab. Machines with lower hours and documented service history sit at the upper end of the class range, while high-hour units or those requiring visible structural or powertrain attention trade below the class average. Year of manufacture and compliance with current emissions standards are additional factors that influence where any individual unit falls within the band.
