Equipment Overview
The Komatsu HD405 is a rigid dump truck built for quarry, construction, and small-scale mining operations, the smallest model in Komatsu’s mechanical-drive rigid dump truck range. It carries a 40-tonne maximum payload and a 24 m³ heaped body, delivering 386 kW of gross power, suited to sites where a compact turning radius and strong traction matter as much as raw haul capacity.
Power comes from a Komatsu SAA6D140E-7 six-cylinder diesel engine producing 386 kW (518 hp) gross and 383 kW (514 hp) net at 2,000 rpm, with 2,169 N·m of maximum torque. The engine meets U.S. EPA Tier 4 Final emission standards, using a diesel particulate filter and selective catalytic reduction system. A seven-speed K-ATOMiCS automatic transmission drives the rear axle, and a McPherson-strut front suspension gives the HD405 a 7.9 m turning radius, among the tightest in its class.
