Strength and performance
Whether you are looking to keep blasting, loading and dump areas clean, or construct and maintain haul roads, dozers have a direct impact on your fleet’s productivity. With new mainframes featuring twice the design life over previous models, Komatsu mining dozers are engineered to be powerful and durable.
- Up to 18% productivity increase over previous models
- Over 20% more engine power in the reverse direction versus forward direction
- 10% reduction in fuel consumption with automatic transmission with lockup torque converter compared to operation in manual gearshift mode
