The Tier 4 interim WA380-7 will save you 10% on your fuel bill over the previous model. Two engine power modes, power and economy, let the operator match his work mode to the job at hand. The large capacity torque converter with enhanced lock-up gives the WA380-7 terrific digging power in the pile and climbing ability. SmartLoader Logic ensure that the WA380-7 works most efficiently under low demand conditions to ensure further energy and fuel savings.

WA380-7 Walkaround  >


Dual-Mode Engine Power Select System

This wheel loader offers two selectable operating modes—E and P.


E Mode

This mode provides maximum fuel efficiency for general loading.


P Mode

This mode provides maximum power output for hard digging operations or hill climb applications.

Komatsu SmartLoader Logic

The WA380-7 provides Komatsu SmartLoader Logic, a new engine control system. This technology acquires data from various sensors in the vehicle and controls the engine to yield enough torque for each work phase. Engine torque requirements for a wheel loader vary depending on working conditions. For example, the loader requires higher torque for digging in V-shape loading, but less torque when traveling with an empty bucket. This technology limits the engine torque during less demanding work, therefore saving fuel. Komatsu SmartLoader Logic functions automatically and doesn’t interfere with operation, saving fuel without decreasing production.

Large-Capacity Torque Converter

The newly designed power train has a large capacity torque converter for optimum efficiency. The WA380-7 has greater productivity in V-shape loading applications because the increased tractive effort does not require full throttle. The improved hill climbing ability allows the WA380-7 to up-shift gears faster because of improved acceleration. The WA380-7 can achieve higher gear ranges and maintain higher travel speed when working in load-and-carry applications. In most applications, production is increased and fuel consumption is reduced, resulting in improved fuel efficiency.

Large LCD Monitor

The LCD monitor displays various information of the machine such as ECO Guidance, operation records, and maintenance information. Since the LCD unit has a wide full color display area, it displays more information and is easy to read. For example, the “Operation Records” menu displays various records of the actual working hours, average fuel consumption, idling hours, and E mode operation ratio, as well as other features. These records are displayed in the form of daily data and time period data. Data can be displayed in 25 languages to support operators around the world. The controls for the automatic air conditioner are integrated into the LCD monitor panel to allow the operator to easily and precisely set the cab atmosphere. The monitor clearly displays abnormality codes to alert the operator. These codes are stored for trouble shooting. The monitor also provides for advanced monitoring of system parameters through the Service Mode to aid in troubleshooting and reduce downtime.

Low Fuel Consumption

Komatsu added many new features on the WA380-7 to reduce fuel consumption. These features enable further fuel efficiency by optimally controlling engine power and matching the Komatsu designed and produced high efficiency power train components and hydraulic system.

Operator Seat with EPC --Electronic Pilot Control-- Levers

The work equipment control system has an EPC lever console integrated into the higher capacity seat and moves with the seat. The angle of the armrest is fully adjustable for optimum operator comfort. An F-N-R switch is now incorporated in dual and three lever configurations as well as the optional monolever configurations. A heated seat is now standard.

Rear Full Fenders

The WA380-7 has a new rear fender option. The plastic rear fenders now open outward, keeping the force to open the engine doors low, even when there is mud or snow on the fenders. The fenders swing far out of the way to give the technician easy access to the engine compartment. Mudflaps are also included on the rear fenders.

Rear View Monitoring System

The operator can view the rear of the machine with a full color monitor that is located on the right side of the cab. This monitor can be always on or only on when the loader goes into reverse. Visual guidelines can also be added for more convenience.

Remote Bucket and Boom Positioner

The operator can set the bucket angle and remote boom positioner from the cab. Both upper and lower boom positions are adjustable in the cab with the push of a button. The bucket positioner can memorize three horizontal settings, allowing the operator to easily change attachments without having to reset the bucket position. In each horizontal setting, the operator can adjust the setting with the switch in the cab. This can help save the operator time when changing attachments.

Swing-out Type Cooling Unit

The large capacity cooling unit swings open for cleaning. It features wider spacing of cooling fins to reduce clogging. A rear screen is also standard to reduce the amount of debris that can enter the engine compartment.

Variable Displacement Piston Pump and CLSS

The variable displacement piston pump combined with the Closed-center Load Sensing System (CLSS) delivers as much hydraulic flow as the job requires, preventing wasted hydraulic flow. Minimized loss contributes to better fuel economy.
