[. . . ] GROSS HORSEPOWER 331 kW 444 HP @ 2000 rpm NET HORSEPOWER 321 kW 430 HP @ 2000 rpm Easy-to-Load Body MAXIMUM GVW 66, 875 kg 147, 435 lb Heaped capacity: 22. 3 m3 29. 2 yd3 Low loading height: 2970 mm 9'9" Robust body constructed of thick wear-resistant steel having 400 Brinell hardness. High Performance and Environment friendly SAA6D140E-3 Engine Gross Horsepower: 331 kW 444 HP Hydropneumatic Suspension for All Terrain The hydropneumatic suspension assures a comfortable ride even over rough terrain. Wide, Spacious Cab The wide cab offers a comfortable operator environment. Interior noise level: 76 dB(A). Lubrication-Free Oscillating Hitch The lubricant-free oscillating hitch means lower operating costs. Tiltable Cab The cab can be tilted rearward to provide easy service. Fully Hydraulic Articulated Steering Light and easy operation Minimum turning radius: 8. 7 m 28' 7" 2 Interaxle & Differential Locks for Excellent Traction in Rough Terrain The oil-cooled multiple-disk interaxle lock and differential locks can be turned on and off during travelling. Also the differential locks can lock up all 3-axles differentials for maximum traction. Reliable Wet Type Multiple-Disk Brake and Retarder Fully hydraulically controlled wet multiple-disk brake. [. . . ] This high technology system assures smooth shifts without shock. Large Capacity Body and Box Section Frame Structure The 22. 3 m3 29. 2 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 shape provides excellent load stability. Rugged enough for the toughest jobs, the HM400's frame is designed using a rigid box structure with high strength low alloy steel. Interaxle & Differential Locking Systems The full-time six-wheel drive system reduces slippage. A wet multiple-disk 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. In addition, the differential lock switch, which is a three position switch, can lock up the rear axle differentials only, or all axles for maximum performance in the worst conditions. Fully Hydraulically Controlled Wet Multiple-Disk Brakes and Retarder Wet multiple-disk brakes have been proven on Komatsu dump trucks and wheel loaders. The large-capacity wet-multiple disk brakes also function as a highly responsive retarder which gives the operator great confidence while travelling downhill. Retarder Absorbing Capacity (continuous descent): 405 kW 544 HP 583 kW 782 HP (with optional exhaust retarder) Articulated Steering Fully hydraulic articulated steering offers low-effort operating performance and maneuverability. A minimum turning radius of only 8. 7 m 28' 7" provides the freedom to move about in confined areas. 8. 7 m 28'7" 4 5 OPERATOR OPERATOR ENVIRONMENT ENVIRONMENT Komatsu has developed a state-of-the-art, wide comfortable cab. The low level of vibration and noise ensures maximum productivity from the operator. EASY EASY MAINTENANCE MAINTENANCE The HM400-1 has been designed to keep service time down and productivity up by having a lubrication-free oscillating hitch, a reduced number of grease points, easy access to filters, and longer intervals between oil changes. Tiltable Cab The cab can be tilted rearward to provide easy maintenance/service for the engine and transmission. Note: An external hydraulic pump is required to tilt the cab. Extended Service Intervals In order to minimize operating costs service intervals have been extended. Engine oil: 500 hours Transmission oil: 1000 hours Engine & transmission filters: 500 hours Wide, Spacious Cab The wide cab provides a comfortable space for the operator and a full size buddy seat. Large, electrically operated windows and the operator's seat positioned to the left side ensure superior visibility. Hydropneumatic Suspension for All Terrain The hydropneumatic suspension assures a comfortable ride even over rough terrain and ensures maximum productivity and operator confidence. Guards Oil seal Taper roller bearing Air Suspension Seat The air suspension fabric covered seat which is adjustable to the operator's weight is provided as standard. The air suspension seat dampens vibrations transmitted from the machine and reduces operator fatigue as well as holding the operator securely to assure confident operation. Ergonomically Designed Cab The ergonomically designed operator's compartment makes it very easy and comfortable for the operator to use all the controls.
