Auto Retard Speed Control (ARSC)

Auto Retard Speed Control (ARSC) allows to easily set a constant downhill travel speed and lets the operator concentrate on steering. Speed can be adjusted appropriately to the slope grade at an increment of 1 km/h by clicking the control lever (± 5 km/h max.)

Komatsu Rigid Dump Trucks

Small turning radius

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 radius of the truck.

Payload meter (PLM)

The Payload meter (PLM) manages the payload of each hauling cycle and analyzes the truck’s production volume and working conditions for a specific period. Loaded weight is displayed in real time, both on the cab’s monitor and by external display lamps.

Safety first

Safe cab access thanks to the low angle of the front stairways with handrails, slip-resistant.

Speed limiter: Maximum travel speed is limited independently for both empty and loaded conditions

Antilock brake system (ABS) (optional): This system prevents the tires from locking when using the service brake and the retarder, thus minimizing skidding under slippery conditions.
