Komatsu HM400-3 Articulated Dump Truck


Articulated Dump Trucks, Off-Highway

HM400-3 articulated dump truck is powered by a 469 horsepower, Tier 4-Interim Komatsu SAA6D140E-6 engine. Maximum GVW is 162,569 pounds, and the truck can haul up to 44.1 tons, or 40 metric tons, at its maximum ground speed of 34.7 mph. Compared to the HM400-2, body capacity and payload have been increased. The articulated hauler's 10 foot 5 inch-loading height matches 40-to-60-ton excavators or wheel loaders in the range of 5.5 to 7.5 cubic yards. The ADT has the Komatsu Traction Control System, which has speed sensors located on four wheels that detect tire slippage, after which automatic application of the inter-axle differential lock occurs. The fully automatic transmission uses an advanced electronic system to eliminate shift shock and torque cutoff. The system automatically selects the gear based on vehicle speed, engine speed, and shift position selected. The Komatsu Equipment Management Monitoring System (EMMS) has enhanced diagnostic features that give the operator and technicians greater monitoring and troubleshooting capabilities. EMMS continually monitors all critical systems, preventative maintenance schedule, and provides troubleshooting assistance to minimize diagnosis and repair time. With the introduction of the Komatsu CAREProgram, every Komatsu Tier 4-I machine comes standard with complimentary factory scheduled maintenance for 2,000 hours or the first three years (whichever occurs first), and includes two complimentary Komatsu Diesel Particulate Filter (KDPF) exchanges within the first five years. The Komatsu CARE program covers all new Komatsu Tier 4 Interim equipment, whether rented, leased or purchased.
