Increased Fuel Efficiency and Environmental Performance

Powerful and Environmentally Friendly EU Stage V engine Komatsu SmartLoader Logic E-Light engine mode Large-capacity torque converter with standard lock-up Adjustable idle shutdown

Komatsu SmartLoader Logic

The WA480-8 provides Komatsu SmartLoader Logic, a fully automatic engine control system. Without interfering with normal operations, this technology acquires data from various sensors in the vehicle and delivers optimal engine torque for each work phase. It limits torque during less demanding operations and reduces fuel usage without decreasing production.

New E-Light mode

Switched on by default, the new E-Light mode prioritizes a lower fuel consumption. For increased fuel efficiency, the engine matches power to the current working phase. Electronically controlled hydraulic pumps for the work equipment and steering system prevent wasted hydraulic flow and deliver the exact amount of oil required for all machine movements.

Faster Load & Carry

The sequential 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 2nd to 4th gear. It noticeably increases travel speed, particularly when going uphill, thanks to the larger tractive force. It also significantly reduces fuel consumption by eliminating converter losses.

Precision control

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. The WA480-8 also features variable-displacement pumps on both the hydraulic and steering systems. These pumps deliver the exact amount of oil required, dramatically improving fuel efficiency.

Diesel particulate filter regeneration

No interruption or extension of daily work is required to regenerate the diesel particulate filter system. Due to its superior Komatsu technology, KDPF regeneration takes place automatically, at any time.

Designed and built by Komatsu

The engine, hydraulics, power train, front and rear axles are original Komatsu components. All components, right down to the smallest screw, are subject to the highest quality standards, and are fully co-ordinated with one another for maximum efficiency and reliability.

Axle oil cooling system

Overheated axle oil can cause a decline in productivity due to required machine cool downs. To maintain high efficiency in Load & Carry applications, the Komatsu WA480-8 is equipped as standard with an axle oil cooling system that keeps oil at a constant temperature even over long hauling distances.

New high efficiency buckets

Soil slips easily from the redesigned bucket, and digging work is more efficient. Operations are quicker and productivity improved, especially in combination with the new auto digging system.

New automatic digging system

The new automatic digging system actuates the bucket tilt and lifting operations by detecting the sensing pressure applied to the work equipment. The system adapts to different types of material with no human intervention required. Operator fatigue is greatly reduced and ideal load capacity ensured.

Waste handling

We configure our wheel loaders to work in the difficult environment of waste handling job sites. Along with heavy duty attachments, we offer solutions to protect your machine against damage.

Heavy-duty axles

The heavy-duty axles allow exceptional service life even under the toughest working conditions. The optional limited slip differentials are most suitable for soft and slippery ground like sand or wet soil.

Aggregate handling specification (option)

With higher payloads and bucket capacities, this specification reduces the number of passes needed to load a truck. It sets new standards for productivity, fuel efficiency and comfort. The optimised Z-bar loader linkage, together with high-efficiency buckets, delivers improved payloads and bucket longevity. Enhancements in the frame structure and the heavy-duty axles, combined with the axles’ oil cooling system and a heavier rear counterweight, provide the necessary stability and durability of this version, which is optimised for material handling.

New high efficiency bucket range

The new Komatsu buckets enable easier bucket fill and significantly higher fill factors, contributing to more efficiency and less fuel consumption. They feature a longer bottom allowing for more content, a wider opening for an easier fill and a new rear shape that enables material to flow easily into the bucket. Their rounded sides give them a higher fill factor, and an integrated spill guard protects the bucket linkage. Flush screws (with BOC) reduce resistance when filling and keep material from clogging when dumping.
