WA430-6E0 Komatsu WA430-6E0 Specifications & Technical Data (2005—2016)

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.

Simple and convenient access to service

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 as standard

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.

Walk-around

The WA430-6 wheel loader sets new standards in traction and fuel consumption for machines of its class. With its combination of very high torque and advanced Komatsu power train technology, the WA430-6 delivers higher levels of performance than ever before. Whatever the job, the WA430-6 can handle it, thanks to its excellent tractive force and the high-power Closed Center Load Sensing System (CLSS). In addition, the SpaceCab™ offers outstanding operator comfort to match this performance.

Engine Performance

Komatsu SAA6D114E-3 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 WA430-6’s new Komatsu SAA6D114E-3 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 173 kW (232 HP) at 2.100 RPM and delivers 1.040 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.

Heavy duty HPCR system (High Pressure Common Rail fuel injection)

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.

Hydraulic quick coupler

The WA430-6 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 WA430-6 is also perfectly suited to work in the timber industry. The robust design of the lifting frame and axles ensures maximum durability.

Safe, convenient access

For easy and safe entry, the WA430-6 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 compliance

The WA430-6 is equipped in accordance with the safety regulations of the machinery guidelines 89/392 EWG ff and EN474.

Wide tread and long wheelbase

A 2.280 mm wide tread and a long wheel base of 3.300 mm give the WA430-6 outstanding stability – enough to handle rough terrain and fast load & carry cycles with the minimum spillage and maximum comfort. With 37° steering articulation to both sides, the WA430-6 is extremely manoeuvrable in tight spaces for faster loading cycles.

Superior dumping height and reach

The long lifting frame allows an enormous dumping height of 2.900 mm and a reach of 1.265 mm that is just as impressive (with 4,2 m³ stockpile bucket in combination with 26.5R25 tyres). With this working range, loading high-sided semi-trailers with a payload of 28 tonnes becomes child’s play.

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.
