Features and benefits

Wheel loader_WA380_Literature linkWA470-8_SAA6D125E-7_engine_350dpi.psd

Conserve fuel

Your engine torque needs to match the demands on the machine to use fuel most efficiently. To help minimize fuel consumption, Komatsu Smart Loader Logic optimizes engine torque.

Wheel loader_WA380_Literature linkWA380_8_Engine compartment.eps

Work efficiently with managed torque

An efficient powertrain helps maximize fuel efficiency and productivity. The large capacity torque converter allows your operators to up-shift gears faster for outstanding acceleration and maintain high travel speed in load-and-carry applications.

Wheel loader_WA380_Literature linkWA380_7_e_p05_01.eps

Choose the best mode for your application

Optimize efficiency with a machine working in the mode suited for the workload. For maximum fuel efficiency for general loading, run in Economy mode and choose Power mode for maximum power output for hard-digging operation or hill climbing.

Minimize environmental impact

Leveraging technology to lower fuel consumption and emissions. Proprietary systems reduce particulates and seek optimal engine performance in all speed and load conditions. EPA Tier 4 final engine cuts NOx by more than 80% vs Tier 4 Interim levels.

Wheel Loader_WA380 7_literature link_e_p07_02.eps

Save time

Your operators can set the bucket angle and remote boom positioner from the cab and adjust upper and lower boom kick-outs with the push of a button. The bucket positioner stores three horizontal settings, so operators can easily change attachments.

Dial in the hydraulic flow needed

Wasted hydraulic flow cuts productivity and performance. Maintain smooth operation and fuel efficiency with a Closed-Center Load Sensing System with variable displacement piston pump, engineered to deliver the hydraulic flow needed.

Wheel loader_WA380_Literature linkWA470_8_en_b02.eps

Operator comfort is key to productivity

Provide your operators with a comfortable enhanced cab environment, featuring heated air suspension seat, electronic pilot control, tilting/telescoping steering, low noise design, and input for audio devices.

Actionable insights

Operators will appreciate quick access to environmental controls, machine functions and troubleshooting help via a high-resolution, 7-inch color LCD monitor display of maintenance information, operational records, ecology guidance and other machine data.

Reduce downtime

Efficient operation isn’t limited to when your machine is running. Large, side-opening gull-wing engine doors, swing-out cooling fan and easily accessible reservoirs and filters mean easier access for maintenance.
