01.特徴 Feature 共通

360° Full Rotating Crawler Carrier

The machine could change travel direction at narrow space without pivot turn and spin turn since upper structure can rotate. The rotating function also eases the machine to unload.

High performance movement and excellent traction

Thick, seamless rubber tracks provide outstanding durability! The rubber crawler is driven by The HST (Hydro Static Transmission) system. Hydraulic drive transmission provides smooth movement.
Rubber crawler width of MST-4000VDR is 850mm which is widest ever in KURU-KURU carrier series. The undercarriage, which has been reinforced with Bridgestone’s high-strength rubber crawlers, achieves stable driving and durability. Running cost will also be reduced.

Electric Control Joystick

Electric control travel lever has been introduced. Intuitive operation is possible with only the left-hand joystick for driving. Driving posture has also been improved compared to conventional machines, reducing operator’s fatigue. In addition, operation systems such as super slow mode, auto cruise (option), horn, spin turn and high speed/low speed switching are integrated into the travel lever, allowing the vehicle to travel as the operator wishes.

Auto Decel function and ECO mode

Engine speed is reduced by 10% in eco mode to reduce fuel consumption. Eco mode can be activated/deactivated on the monitor in the operator seat.
The “Auto Decel function” automatically lowers the engine speed when idling for a certain period of time, improving fuel efficiency and reducing CO2 emissions and noise.
