Komatsu is introducing its PC228USLC-11 ultra short tail excavator. It is said to enable an improved lifting capacity of 21% and a reduction in fuel consumption of 6%. It is also intended to provide improved operator comfort, increased safety features and low in-cab noise levels. The machines rounded cab design allows rotation within the counterweight's swing radius and can manoeuvre in more areas including space-constrained jobsites.
PC228USLC-11 comes with operating weights ranging 23-24.15tonnes and a EU Stage IV engine that is said to optimise performance, reduce emissions and provide advanced diagnostic capability. In addition, a Selective Catalytic Reduction system has been integrated to further reduce NOx emissions using the AdBlue additive.
For safety, KomVision displays a real-time bird's eye view of the excavator and its immediate surroundings to prevent job site incidents and accidental movement at start up.
The cab is mounted on rubber isolation dampers for low vibration levels while the radio offers pre-sets and an auxiliary USB input for connecting external devices.
Additionally, the new viscous fan clutch system aims to reduce both power loss and engine load when maximum cooling is not required. It is also said to lower fuel consumption and contribute to low in-cab noise, 71db(A).
