Komatsu Europe claims that its new WA470-8 wheel loader offers higher output and lower emissions than the model it replaces. Power comes from a Tier 4 Final/Stage IV engine and its fuel consumption is up to 8 % lower than for the WA470-7. The new model retains the proven durability and reliability of the earlier model but also offers improved stability, breakout power and tractive effort. Productivity is improved while fuel consumption has been reduced by up to 8%.
A key innovation is the new auto-digging mode, while the machine also has a new E-light work mode. Another improvement is Komatsu’s redesigned bucket, which is said to further improve penetration and offers better fill factors. The machine can be used for both load and carry applications or truck loading job. Optional extras can be selected to allow the machine to be used in waste handling or quarry applications.
To lower emissions the new loader has a Komatsu diesel particulate filter (KDPF) as well as a selective catalyst reduction (SCR) system. The engine’s advanced electronic control system is said to manage the air-flow rate and fuel injection, combustion parameters and aftertreatment functions. To allow the customer to monitor operations remotely and download working data or carry out diagnostics, the machine is equipped with the KOMTRAX telematics system as well as the Komatsu Care maintenance programme.
