PRODUCTIVITY FEATURES Engine power mode selection system The system allows selection of the appropriate mode between two modes “Power mode” or “Economy mode” according to each working condition. The mode is easily selected using a switch in the operator’s cab. High performance SAA6D140E-5 engine Electronic control system Komatsu’s electronic control system monitors the vehicle performance, optimizing emissions, fuel efciency and noise levels, even under extreme conditions. Power mode Great productivity can be attained by taking full advantage of high output power. It is appropriate for job sites...

OFF-HIGHWAY TRUCK Automatic Idling Setting System (AISS) Small turning radius This system facilitates quick engine warmup and cab cooling/warming. When setting the system ON, engine idle speed is kept at 945 rpm when coolant temperature is 50 °C or lower. Speed automatically returns to 750 rpm when coolant temperature reaches 50 °C. The MacPherson strut type front suspension has a special A-frame between each wheel and the main frame. The wider space created between the front wheels and the main frame increases the turning angle of the wheels. The larger this turning angle, the smaller the turning...

OPERATOR ENVIRONMENT Wide, spacious cab with excellent visibility The wide cab provides a comfortable space for the operator and a full size trainer’s seat. A large electrically operated window and the operator’s seat positioned on the left hand side ensures superior visibility. 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 condent operation by operators and greater productivity. A rear view camera and monitor system is supplied as standard. Easy-to-see instrument panel...

OFF-HIGHWAY TRUCK K-ATOMiCS with “Skip-Shift” function The K-ATOMiCS (Komatsu Advanced Transmission with Optimum Modulation Control System) ensures proper clutch modulation pressure when the clutch is engaged. The total control system controls both the engine and transmission by monitoring the vehicle conditions. This system and newly added “skip-shift” function ensure smooth shifting and responsive acceleration. Viscous mounts reduce the noise transmitted to the cab and achieve a quiet 78 dB(A) noise level “Skip-shift” function Built-in ROPS/FOPS The optimum travel speed automatically selected...

ADVANCED MONITORING SYSTEM Availability rate with vehicle monitoring system The electronic display panel shows current vehicle condition and how to x them with action codes and check results with service codes. Thus, vehicle management is easier and the working rate is higher. At the same time the monitoring data is saved to be used for later troubleshooting. Equipment Management Monitoring System (EMMS) Monitoring network Monitoring system Engine controller Transmission controller This window is normally used as the service meter/ odometer. If the dump truck has any abnormality or needs to be...

OFF-HIGHWAY TRUCK EASY MAINTENANCE Centralized greasing points Greasing points are centralized at three locations. Flange type rims Flange type rims provide easy removal/installation of the tyres. Electric circuit breaker Centralized arrangement of lters The lters are centralized so that they can be serviced easily. A circuit breaker is adopted in important electric circuits that should be restored in a short time when a problem occurs in the electrical system. Extended service intervals In order to minimize operating costs, service intervals have been extended: • Engine oil 500 hours • Hydraulic...

RELIABILITY FEATURES Komatsu components Flat face-to-face O-ring seals Komatsu manufactures the engine, torque converter, transmission, hydraulic units, and electrical parts on this dump truck. Komatsu dump trucks are manufactured with an integrated production system under a strict quality control system. Flat face-to-face O-ring seals are used to securely seal all hydraulic hose connections and to prevent oil leakage. High-rigidity frames Cast-steel components are used in the main frame for highstress areas where loads and shocks are most concentrated. Wet multiple-disc brakes and fully hydraulic...
