Vilvoorde – Komatsu Europe International introduces the HM400-3 articulated truck. With a unique and completely redesigned traction control system, automatic retarder and Komatsu’s new engine emission technology, combined with an optimized cabin layout and increased durability, the HM400-3 is a comfortable, highly productive and low cost production unit.

The HM400-3 features a gross vehicle weight of 73,740 kg with a payload of 40 tonnes at its maximum ground speed of 55.9 km/h. With a flywheel horsepower of 473 hp (353 kW), the HM400-3 is powered by a Komatsu SAA6D140 engine that is EU Stage IIIB and EPA Tier 4 Interim emission certified. Built upon a proven EU Stage IIIA engine platform, Komatsu has leveraged its leadership in technology and innovation to design an environmentally friendly dump truck with more power and lower fuel consumption

Built upon proven Komatsu EU Stage IIIA technology, the SAA6D140 engine provides increased horsepower while lowering fuel consumption and emissions. As a leader in hydraulic technology, Komatsu has developed a hydraulically actuated Komatsu Variable Geometry Turbocharger (KVGT) and an Exhaust Gas Recirculation (EGR) valve, resulting in better precision and air management as well as longer component life. The Komatsu Diesel Particulate Filter (KDPF) has an integrated design that will not interfere with daily operation but keeps the operator aware of its status.

The HM400-3 features the new Komatsu Traction Control System (K-TCS). The K-TCS automatically provides optimum traction on any type of ground. As ground conditions worsen and tire slippage is detected by speed sensors located on four wheels, automatic application of the inter-axle differential lock occurs. If tire slippage continues to be detected then four independent brakes automatically apply to slipping wheels to regain traction and reduce tyre wear.
