26.2 yd³. 1765 hp. Incredible numbers for Komatsu’s largest, most productive wheel loader, the WA1200-6. From the low vibration cab the operator uses his advanced joystick control and modulated clutch drive system to maneuver in tight areas to load trucks up to 320 ton capacity. High stability and breakout force give the operator the confidence he needs to keep up with the production demands of today’s mines.
AJSS is a feedback steering system which has been incorporated to allow steering, forward and reverse direction to be controlled by wrist and finger. With the feedback function, the machine steering angle is the same angle as the lever tilt angle.
The engine output function has "2 modes", Economy or Power. They are selected and controlled automatically. P mode is selected only when digging and approaching the dump truck. This "2 mode" engine control contributes to the reduction of the fuel rate and also improves reliability and durability.
Monitor is mounted in front of the operator for easy viewing, allowing the operator to easily check gauges and warning lights.
The WA1200-6 has the widest tread in its class
14'1'' / 4,300 mm and a long 23'4'' / 7,100mm wheelbase, for maximum machine stability.
