Primary Applications: Covering Engineering Needs Across Multiple Fields
Construction Engineering Sector

Site leveling and earthwork backfilling in infrastructure projects such as roads, airports, and ports.
Foundation preparation for large-scale construction projects, rapidly forming subgrades with high-intensity dozing capability.
Mining and Energy Development

Stripping operations in open-pit mining, efficiently removing overburden soil and rock.
Maintenance of mine roads and site clearance, adapted for rugged terrain and heavy-duty conditions.
Agriculture and Land Reclamation

Farmland improvement, terraced field construction, and land reclamation, achieving precise land leveling through accurate dozing.
Earthmoving tasks in water conservancy projects, including dam construction and river dredging.
International Market Applications
As a classic Komatsu model, the D155A series (e.g., D155A-5) is exported globally to serve diverse infrastructure, mining, and agricultural needs across key markets including Africa, Southeast Asia, and the Middle East.
