‘The ultimate tool’: Komatsu’s new WA800‐8 wheeled loader

Komatsu has unveiled the new WA900‐8 wheeled loader. Designed for maximum operating comfort, the machine offers many customer advantages and is said to offer not only the highest productivity of any wheeled loader in its class, but also up to 17% higher fuel efficiency.

With a 116tonne operating weight, the WA900‐8 allows for 23.2tonne rated load capacity in a standard boom configuration and for 20.5tonne rated load capacity in high lift boom configuration.

Jo Monsieur, group manager for Large Machines at Komatsu Europe, said: “Komatsu designed the WA900‐8 wheeled loader with one major goal in mind: to provide customers with an ultimate tool to let them safely and comfortably achieve lowest cost‐per‐tonne production.

“Not only does this new machine include an efficient engine and offer the highest rated load, but its new and super comfortable cabin is the largest ever on a Komatsu wheeled loader.”

The WA900‐8 meets the latest EU Stage V emission regulations with its Komatsu‐designed, developed and manufactured engine and aftertreatment systems.

Komatsu says the model’s customers will be competitive in tenders and keep the machine working for years thanks to its two diesel particulate filters, two variable geometry turbos, a heavy-duty and cooled exhaust gas recirculation system, new engine control modules, a closed crankcase ventilation system, and lack of AdBlue requirement.

As standard, Komatsu offers up to 14.5m³ buckets that have a redesigned spill guard, increased radius and floor angle and provide better penetration and higher fill factors to boost productivity and income. Their ultra‐strong teeth and enlarged sweeper wings increase uptime and reduce tyre damage, reducing maintenance costs.

A standard high-accuracy payload meter enables work productivity and efficiency to be tracked within 1.5% accuracy, helping avoid dump truck overloads.

The WA900-8’s modulation clutch system gives operators precise control of rim pull, for fast work equipment speeds and a smooth approach for truck loading. Its variable traction control system optimises rim pull on all ground conditions, minimising tyre slippage and lowers maintenance costs.

SmartLoader Logic, Komatsu’s fully automatic on-board engine control, is said to yield precise torque for each work phase, based on the application. By automatically switching between Economy and Power modes it considerably reduces fuel usage, with no loss of productivity.

The new generation WA900‐8 wheeled loader’s hydraulics are improved with a CLSS hydraulic system that delivers power on demand via the variable displacement piston pumps. It keeps the hydraulic oil cool and increases both work speed and fuel economy. Fuel savings are further realised through the machine’s auto idle shutdown system and by ECO guidance tips on the in‐ cab monitor.

Combined with the comprehensive Komatsu CARE support package, the WA900‐8 is said to offer competitive customer value.
