Equipment Overview
The Komatsu D275AX is a large dozer built for heavy construction, mining, and infrastructure work, part of Komatsu’s D275 large dozer family for the Australian and New Zealand market. It has 335 kW (449 hp) of net power, an operating weight of 51,530 kg, and a 14.6 m³ SIGMADOZER blade in standard configuration, suited to waste management, heavy civil earthworks, and applications requiring powerful dozing and ripping.
Power comes from the Komatsu SAA6D140E-5 engine, which meets EPA Tier 3 and EU Stage 3A emission standards. A Hydrostatic Steering System (HSS) delivers smooth, quick, and powerful directional control, and the transmission automatically engages torque converter lock-up once up to speed, transmitting engine power directly for efficiencies close to a direct drive, while an auto-downshift function drops to the optimum gear whenever load increases. The K-Bogie undercarriage oscillates on two fulcrums to keep track rollers in constant contact with the track link, reducing impact loads.
