Increase power while decreasing fuel consumption with Komatsu’s HM400-3 articulated truck, which is powered by a 469-horsepower Tier 4 Interim Komatsu SAA6D140E-6 engine. The 162,569-pound HM400-3 truck hauls up to 44.1 metric tons while achieving a 34.7-mph maximum ground speed. The truck includes features that improve operation such as a new traction control system (K-TCS) that has speed sensors to detect tire slippage and then automatically applies the inter-axle differential lock. Komatsu Advanced Transmission with Optimum Modulation Control System has a six-speed automatic transmission that eliminates shift shock and torque cutoff, ensuring efficient engine operation while minimizing operator fatigue and load spillage.
Additional features:
• Equipped with the KOMTRAX fleet monitoring system.
• Large automatic retarder eliminates inertial acceleration effects.
