The combination of high travel speeds and an efficient engine with low emissions Hydropneumatic Suspension delivers maximum productivity at the lowest cost.

7 The hydropneumatic suspension has been proven on Komatsu 's rigid dump trucks. The front axle suspension employs "De Dion" type design, allowing the machine to ride more smoothly over bumps. The rear-axles are High Performance SAA6D140E-3 Engine Komatsu Designed Electronically Controlled mounted on a dynamic equalizer structure equipped This engine delivers faster acceleration and Transmission with hydropneumatic suspension. The entire vehicle's higher travel speeds with the highest horsepower Komatsu designed Electronically Controlled Transmission called suspension system responds per ton in its class.

8 Advanced technology, such K-ATOMiCS has been successfully employed in Komatsu 's rigid to the ground conditions. as high-pressure electronic controlled injection dump trucks. The electronic clutch modulation system ensures The suspension delivers a system (CRI), air to air aftercooler and an proper clutch pressure when the clutch is engaged. The total comfortable ride and efficient turbocharger enabling the engine to suit control system controls both the engine and transmission maximizes the productivity. low emission. High torque at low speed, by monitoring the vehicle conditions.

Large Capacity Body and Box Section Frame Structure The m3 yd3 heaped capacity is among the highest in its class, and the low loading height of 2970 mm 9'9". enables easy loading. The body is built of thick wear-resistant steel with a Brinell hardness of 400, and the body Interaxle & Differential Locking shape provides excellent load stability. Systems Rugged enough for the toughest jobs, the HM400 's frame is designed using a The full-time six-wheel drive system rigid box structure with high strength reduces slippage.

10 A wet multiple-disk low alloy steel. interaxle clutch also locks the three axles in unison for greater traction. The interaxle lock and differential locks can be switched on and off while the truck is travelling, thereby boosting productivity. Fully Hydraulically Controlled In addition, the differential lock switch, Wet Multiple-Disk Brakes and Retarder which is a three position switch, can Wet multiple-disk brakes have been proven on articulated Steering lock up the rear axle differentials only, Komatsu dump trucks and wheel loaders. They Fully hydraulic articulated or all axles for ensure highly reliable and stable brake steering offers maximum performance.
