KOMATSU is introducing the latest generation of wheel loaders. 

The WA475-11 and WA485-11 are said to be packed with state-of-the-art technology and offer "great performance, efficiency, and operator comfort". 

At the heart of new Dash 11 generation wheel loaders is a newly developed Komatsu diesel engine which is characterised by extremely high torque in the low speed range. This new engine is combined with a Komatsu-designed hydro-mechanical-transmission (HMT), resulting in "unmatched performance, power reserves, fuel efficiency and ease of operation for all transport and loading tasks".

The WA475-11, for example, demonstrates a 14 per cent improvement in fuel efficiency over its Dash 10 predecessor, while the WA485-11 achieves a remarkable 29 per cent increase in fuel efficiency compared to its predecessor WA480-8.

Thanks to a constant variable gear ratio, the engine stays in a highly efficient fuel zone. Variable speed control makes it possible to individually adapt the machine's maximum speed to the requirements of the job site. The adjustable variable traction control effectively limits wheel spin in difficult ground conditions.

Compared to its predecessor WA480-8, the WA485-11 has experienced a significant upgrade in payload and bucket capacity. All machine components have been adapted to a permanent payload of 8,800 kg and can even be increased to 9,300 kg in an aggregate handling variant, which helps to reduce the number of loading cycles required depending on the vehicle size.

A press release from the manufacturer added: "Komatsu's commitment to sustainability is evident in the new wheel loaders' advanced emissions control systems, which meet EU Stage V standards.

"On top of that, the well-proven Komatsu exhaust system includes a diesel particulate filter (KDPF) and, together with the Selective Catalyst Reduction (SCR) system, which further reduces NOx emissions using AdBlue.

"These technologies, in conjunction with the particularly low-emission combustion, allows the diesel particulate filter to be replaced only every 8,000 hours; this interval can be extended even further by using particularly low-ash engine oils."

Another new feature is the variable power control, which enables the lifting speed to be controlled independently of the accelerator pedal. 

The new, operator-friendly and spacious cab offers generous all-round glazing and has an interior noise level of just 70 dB(A). A new air-suspended seat dampens vibrations and thus ensures a more comfortable driving experience.

The “automatic bucket filling” and other assistance functions help the operator maintain productivity even during long shifts.
