Komatsu Europe is launching its next generation wheel loaders, the WA475-11 and WA485-11. The two new models are packed with state-of-the-art technology and offer great performance, efficiency, and operator comfort for a maximised customer value, says Komatsu.
At the heart of new Dash 11 generation wheel loaders is a newly developed 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% improvement in fuel efficiency over its Dash 10 predecessor, while the WA485-11 achieves a remarkable 29% 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 the 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.
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 catalytic 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 optimised Z-bar linkage offers up to 20% more lifting power and a higher production rate of tons per hour. The upgraded lifting speed and class-leading machine stability help to increase productivity, especially in tight V-shaped loading applications.
In addition, the hydraulic response time and the tipping or lifting speed can be adjusted to specific application requirements. The new, operator-friendly and spacious cab offers generous all-round glazing and has an interior noise level of just 70 dB(A). The heated rear window is angled, which effectively prevents dirt from sticking on the rear screen.
The lever console has a new command control switch and is adjustable on a 5-way axis for each operator. The increased internal air pressure prevents dust and other particles from entering the cab. For easy and safe entry and exit, both machines are equipped with a rear-hinged door, angled steps and large handrails.
