High Productivity and Low Fuel Consumption
Powerful Engine
The electronically controlled fuel injection timing in the SAA6D125E-3 engine provides optimum combustion of fuel at both low and high speed/power applications.This system also provides fast throttle response to match the machine’s powerful rim pull and fast hydraulic response.
195 kW, 261 HP
The common rail type fuel injection system provides maximum power with minimum emissions.This engine meets EPA Tier II emission regulations and EC second emission regulations.
Low Fuel Consumption
The fuel consumption is reduced greatly because of the low-noise, high-torque engine and the large-capacity torque converter with maximum efficiency in the low-speed range.
Reduction of Fuel Consumption: 15% (compared with Dash 3 technology).
Dual-Mode Select System
This wheel loader offers two selectable operating modes— Normal and Power. The operator can adjust the machine’s performance by flipping a switch.
Normal Mode: This mode provides maximum fuel efficiency for most of general loading.
Power Mode: This mode provides maximum power output for hard digging operation or hill climb.
Transmission Mode Select System
This operator controlled system allows the operator to select manual shifting or three levels of automatic shifting (low, medium, and high).
shifting is performed at relatively low engine speeds, suitable for general excavating and loading.
Auto. M: Gear is shifted at medium engine speeds between those of L and H modes.
Auto. H: This mode provides large rim pull and shor t cycle time since gear shifting is performed at relatively high engine speeds, suitable for load and carry operation on uphill.
New Dual-Speed Hydraulic System
Komatsu’s dual-speed hydraulic system increases operational efficiency by matching the hydraulic demands to work conditions.
Oil from the switch pump is completely returned to the tank when digging and breaking out, therefore, hydraulic flow to the loader is reduced and pressure is increased.This reduces horsepower demand from the engine and makes the operation more efficient. Kick-down switch signal also controls the oil flow. This new technology is greater productivity at the lowest operating cost.
Manual: Transmission is fixed to gear speed selected with gear shift lever.
Auto. L: This mode provides smooth gear change and low fuel consumption since gear
Maximum Dumping Clearance and Reach
The long lift arms provide high dumping clearances and maximum dumping reach.The operator can even level loads on the body of a dump truck easily and efficiently.
Long Wheelbase/Articulation Angle of 40˚
The longest wheelbase in class and the widest tread provide improved machine stability in both longitudinal and lateral directions. Since the articulation angle is 40 can work efficiently even in the tightest job sites.
