With the introduction of the PW168-11 and PW198-11 wheeled excavators Komatsu is expanding its range of short-tail models, rounding up the operating weights of these popular machines to 20 tonnes.
The excavators are said to be compact, easy to transport, powerful, comfortable, versatile, reliable and durable, a response to customer insights and suggestions according to the company. The machine has been designed with an optimized boom and engine at the rear to improve lifting performance while the driving performance of the new models is claimed to be first class, thanks to a low centre of gravity, which improves machine stability.
Both models are powered by a 4-cylinder Komatsu diesel engine (110kW or 129kW) that meets current EU Stage V emissions standards. The machines can run on environmentally-friendly HVO diesel fuel as standard. New Komatsu diesel particle filters, which need replacing only after 8,000 hours, extend service intervals and enable longer periods of uninterrupted work. Exhaust gas treatment is carried out fully automatically, without the need to idle, so no disruption of the workflow.
Cab-wise operator comfort is taken care of with a new premium seat with multi-stage ventilation and seat heating for those cold days. All-important functions can be operated via the joysticks, and the excellent all-round visibility is supported by four cameras with a bird’s eye view as standard.
As a popular go-to machine, the mobile excavator is increasingly being used with a tiltrotator and 3D guidance system. The new models are compatible with any system and come ready to use with a tiltrotator as well as for 3D guidance systems. With useful extras such as joystick steering, tool control management or trailer coupling, the PW168 and PW198 come prepared for tough and demanding construction environments.
With a low transportation height of just 3.1m, transport on standard low-bed trailers with a loading height of up to 4m is possible. The short rear overhang of 1.85m (PW168- 11) or 1.9m (PW198-11) makes the machines ideal for narrow construction sites.
For ease of service and maintenance, all access points are centralized and easily accessible from ground level behind steel flaps. All important functions are displayed as standard via the machine monitor and the Komtrax fleet management system.
