[. . . ] 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. Viscous mounts support the cab while absorbing vibrations and noise. 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. [. . . ] 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. They ensure highly reliable and stable brake performance. 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. The result is more confident operation by operators and greater productivity. Fewer Grease Points We have minimized the number of grease points by using maintenance-free rubber bushings and a lubrication-free oscillating hitch. Viscous Cab Mounts Viscous mounts reduce the noise transmitted to the cab and achieve a quiet 76 dB(A) noise level. Electric Body Dump Control Lever The extra light lever makes dumping easier than ever. The following guards are provided as standard: Protective grille for rear window Engine underguard Transmission underguard Propeller shaft guards Exhaust thermal guard Fire prevention covers Supplementary Steering and Secondary Brakes Supplementary steering and secondary brakes are standard features. Steering: ISO 5010-1992, SAE J1511 Brakes: ISO 3450-1996, SAE J1473 Steering Wheel and Pedals Low effort pedals reduce driver fatigue when working continuously for long periods. The tiltable, telescoping steering column enables operators to maintain the optimum driving position at all times. Easy-to-See Instrument Panel The instrument panel makes it easy to monitor critical machine functions. In addition a caution light warns the operator of any problems that may occur. Problems are recorded in the monitor and indicated as servic codes. This makes the machine very friendly and easy to service. Built-in ROPS/FOPS These structures conform to ISO 3471 and SAE J10401988 standards. 6 7 HM400-1 ARTICULATED DUMP TRUCK STANDARD EQUIPMENT Engine: Alternator, 50A/24V Batteries, 2 x 12V 170AH Exhaust muffler Komatsu SAA6D140E-3 Starting motor, 1 x 11. 0 kW Cab: Ashtray Can holder Cigarette lighter Electronic display/monitoring system Electronic hoist control system Heater and defroster Operator seat, reclining, air suspension type with retractable 78 mm 3" width seat belt Passenger seat with retractable seat belt Power window Tiltable ROPS Cab with FOPS, sound suppression type Space for lunch box Steering wheel, tilt & telescopic Sun visor, front window Two doors, left and right Lighting system: Back-up light Hazard lights Headlights with dimmer switch Indicator and stop and tail lights Safety: Anti-slip material on fenders Automatic supplementary steering Back-up alarm Coolant temperature alarm and light Hand rails for platform Electric horn Ladders, left and right side Protective grille for rear window Rear view mirrors Steering joint locking assembly Under view mirror Guards: Engine underguard Exhaust muffler thermal guard Fire prevention covers Propeller shaft guards, front and rear Transmission underguard Other: Centralized greasing Differential locks in all axles, clutch type Electric circuit breaker, 24V Mud guards Side marker Body: Electronic hoist control system Tires: 29. 5 R25 HM400-1 ARTICULATED DUMP TRUCK SPECIFICATIONS SPECIFICATIONS ENGINE Model.
