Increased Power and Performance With Hydrostatic TransmissionThe WA150-6 incorporates Komatsu's Hydrostatic Transmission (HST) which allocates only as much power as is needed for a given application. The engine power is transmitted hydraulically to a transfer case, then mechanically out to the differentials and to the four driving wheels, making the WA150-6 a very powerful yet efficient machine that responds quickly and smoothly to varying job conditions.
By adjusting automatically to the tractive effort demands of the work at hand, Komatsu's HST provides for quick travel response and aggressive drive into the pile. The full auto-shifting feature eliminates gear shifting and the kick-down switch gives the operator the ability to concentrate on digging and loading operations for faster cycle times and increased productivity.
Komatsu's Hydrostatic Transmission also provides the loader with dynamic braking. When the loader decelerates, the HST system acts as a dynamic brake causing the loader to slow down without using the wet disc brakes. Dynamic braking can also hold the loader on most workable slopes.
Increased Durability And ReliabilityThe wet multi-disc brakes and fully hydraulic braking system, combined with dynamic braking, mean lower maintenance costs and higher reliability. The dynamic braking function means you don't have to use the wet disc brakes as often, increasing overall brake disc life. The wet disc brakes are fully sealed keeping contaminants out and reducing wear and subsequent maintenance. This also means no air system to bleed and no condensation of water that can lead to corrosion and freezing.
Highly reliable and exclusively designed electronic components such as controllers, connectors, sensors and wiring have undergone extensive testing to ensure reliability in the harshest of conditions. The electronic connectors are DT-type and seal against dirt and moisture. Flat face-to-face O-ring seals are used to securely seal hydraulic hose connections and all hydraulic cylinders are protected by metal guard rings for additional reliability. |
