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...

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...

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...

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 •...
