Highway Subbase Compaction: 40 km Road Rehabilitation in Southeast Asia

A national road authority contracted a local civil engineering firm to rehabilitate 40 km of deteriorated two-lane highway. The project required full-depth reclamation of the failed subbase layer and recompaction before new asphalt paving. HCN 120 kN vibratory plate compactors on Komatsu excavators achieved 98% Modified Proctor density across all test sections, enabling the paving contractor to proceed without delays.

Airport Snow Management: Zero Operational Disruption Through Winter in Northern Europe

A regional airport in Northern Europe handles 800,000 passengers annually and cannot afford runway closures. After experiencing two costly operational disruptions the previous winter, the airport authority invested in a fleet upgrade — replacing walk-behind snow removal with HCN hydraulic snow blowers and pusher boxes on four Bobcat skid steers. The result: zero runway closures through a record-snowfall winter.

Open-Pit Mining Rock Breaking: Secondary Fragmentation Productivity Improvement in Australia

An Australian iron ore operation was losing significant crusher productivity to oversize rock fragments requiring secondary fragmentation before crusher feed. Existing secondary fragmentation by blasting was causing pit closure delays. Three HCN HB-3000 hydraulic breakers — rated 12,000 J impact energy — on Hitachi ZX490 excavators reduced secondary fragmentation cycle time by 34% and eliminated pit closure requirements during secondary breaking operations.
