Equipment Overview
The Komatsu HM300 is an articulated dump truck built for off-road hauling across broken, uneven ground, part of Komatsu’s HM range alongside the larger HM400. It carries a 28-tonne rated payload and a 17.1 m³ heaped body, producing 248 kW of gross power, suited to quarrying, civil earthworks, and general construction hauling.
Power comes from a Komatsu SAA6D125E-7 engine meeting EPA Tier 4 Final emission standards, rated at 248 kW (332 hp) gross and 242 kW (325 hp) net at 2,000 rpm. The K-ATOMiCS transmission auto-shifts through six forward and two reverse gears with a lock-up torque converter, driving all six wheels, and selectable power and economy modes adjust the shift pattern to suit the job. The Komatsu Traction Control System manages wheel slip on soft or slippery ground, and wet multiple-disc brakes double as a retarder rated at 526 hp of absorption capacity for controlled descents.
