WA380-6 Komatsu WA380-6 Specifications & Technical Data (2006—2013)

Advanced machine design

The WA380-6 features the ideal combination of a highly efficient drive line, powerful hydraulics and excellent stability. Its outstanding rimpull makes it easy to penetrate even the densest materials and enables higher productivity in V-shaped loading. With the powerful hydraulic system, filling the bucket is as fast and efficient as possible. Meanwhile, the high stability ensures the machine is safe to operate even when the loaded material is unexpectedly heavy. Furthermore, the boom suspension system, which is fitted as standard, minimizes spillage when transporting the material. This reduces costs and extends the lifetime of the bearings and bushings.

Intelligent gas pedal

Our innovative new thrust-sensing gas pedal automatically helps the operator match the timing of gear shifts to the load. In heavy-duty work, requiring high rimpull and maximum acceleration, the operator tends to press heavily on the gas pedal. The machine anticipates this and shifts up gears as late as possible. In light-duty work, where fuel consumption is a major factor, the operator will intuitively press the gas pedal lightly. Again, the machine anticipates this – and shifts up gears as early as possible to achieve the best fuel efficiency.

EMMS (Equipment Management and Monitoring System)

This completely new type of monitoring system is clearly structured and easy to read because it is directly in the operator’s field of view. If there is a malfunction, it immediately displays the details in the chosen national language and in plain text in the display field. This system not only has an error memory and a self-diagnosis function, but also a service interval display. This significantly simplifies service work and the operator is notified on time of the regular oil and filter changes. The operator and customer-service engineer are constantly informed about the optimum machine state so that problems don’t even occur in the first place.

Service access

The service doors are designed as gull-wing doors. They allow you convenient and safe access to the daily service points from the ground.

Centralised filter arrangement

With all filters collected into a centralised arrangement, the down time for servicing is reduced to a minimum.

Centralised lubrication system

The centralised lubrication system reduces the daily service work to the absolute minimum. Its robust piping with protective equipment in all areas ensures consistent lubrication amounts, operating reliability and electronic monitoring with a malfunction signal in the cabin. This increases the machine’s service readiness and service life while lowering repair and service costs.

Komatsu SAA6D107E-1 Engine

Komatsu SAA6D107E-1 engine with high pressure common rail injection delivers ample power in a fuel efficient way. The engine meets EU Stage IIIA and EPA Tier III emissions regulations.

New ECOT3 Engine

The WA380-6’s new Komatsu SAA6D107E-1 engine features higher torque, better performance at low speed, excellent throttle response and advanced electronics. The result is unequalled productivity and the lowest fuel consumption. The engine develops 143 kW (192 HP) at just 2.100 RPM and delivers 963 Nm of torque at just 1.500 RPM. It is designed and manufactured by Komatsu to the highest engineering and quality standards (including the Komatsu-manufactured electronic components) guaranteeing the highest reliability and durability no matter what the challenge. The engine reaches its max. performance of 152 kW/204 HP at already 1.650 RPM.

Heavy Duty HPCR System

A high pressure pump pumps fuel into an accumulator chamber or ‘Common Rail’. An ECU (electronic control unit) then optimizes fuel injection from the common rail into the engine cylinders. This improves engine power and fuel efficiency, reducing emission and noise levels.

New Combustion System

Our new combustion system optimises combustion timing and ignition. Thanks to extensive computer simulations and analyses, its specially designed combustion chamber reduces NOx and particulates emissions, fuel consumption and noise levels.

Electronic Control System

Komatsu’s electronic control system monitors the vehicle performance, optimising emissions, fuel efficiency and noise levels, even under extreme conditions.

Air-to-Air Charge Air Cooling System

By cooling the compressed air supplied by the turbocharger to the cylinders, this system optimises combustion efficiency, reduces emissions and improves engine performance.

Faster Load & Carry with Optional Torque Converter Lock-Up

The optional torque converter lock-up system delivers unbeatable productivity and fuel efficiency in load & carry and short distance transport applications. The operator can engage the system from 3rd to 4th gear. It noticeably increases travel speed, particularly when going uphill, thanks to the larger tractive force. At the same time, it eliminates converter losses significantly reducing fuel consumption.

Precision control with ease

The WA380-6 features variable-displacement pumps on both the hydraulic and steering systems. These pumps deliver the exact amount of oil required, dramatically improving fuel efficiency. Komatsu’s CLSS hydraulics enables extremely precise control of the work equipment, and ensures that the bucket, boom and hydraulically driven attachments can all move smoothly at the same time.

Safe, convenient access

For easy and safe entry, the WA380-6 includes an access ladder with self-cleaning, anti-slip steps inclined forward at 8° on both sides of the cabin. The cab doors are hinged at the rear of the cab for the widest opening angle – even the right-side door can be fully opened.

Quick-reverse hydraulic fan

A push-button switch in the cab allows the operator to run the radiator fan in reverse for working in dusty environments. This can be easily done while the machine is in operation and without needing to stop the engine. To further reduce cleaning times, the machine can be equipped with an automatic reversible fan that can be set to clean at intervals between 10 minutes and 2 hours.

Side-by-side radiator mounting

The side-by-side radiator arrangement together with an air conditioner condenser that is mounted in the air stream ensures easy access when intensive cleaning is required. This makes the machine the ideal choice for recycling applications where easy cleaning is an absolute must.

Safety regulations

The WA380-6 is equipped in accordance with the safety regulations of the machinery guidelines 89/392 EWG ff and EN474.

Universal bucket

This type of bucket is impressive because of its excellent penetration and loosening properties and its good material holding properties. This universal bucket can be equipped with flush mount adapters and interchangeable teeth.

Earthmoving bucket

The earthmoving bucket with a one-piece bucket bottom is suited both for earthworks and loading cohesive material. The slanted sides give powerful penetration. It is equipped either with flush mount adapters and interchangeable teeth or also with a rear removable edge.

Hydraulic quick coupler

The WA380-6 can change attachments in a matter of seconds with a market compatible or HD wedge type quick coupler. With the wedge type quick coupler, featuring a unique and innovative design, the offset to the original connection points is reduced to a minimum. Thus, lifting forces remain almost the same compared to a direct mounted bucket.

A comprehensive range of attachments

The log grapple: With its sturdy structure and its great hydraulic power and a special tilting cylinder, the WA380-6 is also perfectly suited to work in the timber industry. The robust design of the lifting frame and axles ensures maximum durability.
