Equipment Overview
The Komatsu D65PX-18 is a low ground pressure dozer built for grading and earthmoving on soft or wet ground, part of Komatsu’s -18 series crawler dozer range for the Australian and New Zealand market. It has 162 kW (217 hp) of net power, an operating weight of 22,830 kg, and a 3.7 m³ straight tilt blade in standard configuration, suited to soft, wet, or unstable ground where its long-track, low-ground-pressure undercarriage delivers outstanding flotation.
Power comes from the Komatsu SAA6D114E-6 engine, a 6-cylinder, 8.85-litre unit built to U.S. EPA Tier 4 Final and EU Stage V emission standards, using a combined SCR and diesel particulate filter aftertreatment system. A hydrostatic steering system (HST) transmits power to both tracks for smooth, powerful turns and a 2.2 m minimum turning radius, and the Parallel Link Undercarriage System (PLUS) uses rotating bushings to cut undercarriage maintenance costs by up to 40%. The wide 915 mm shoes keep ground pressure to 29.6 kPa.
