Komatsu America has introduced PC2000-11 hydraulic excavator which it says is designed to load 70- to 200-tonne rigid frame haul trucks.
Komatsu America’s product marketing manager Robert Hussey says: “The PC2000-11 has a simplified power module (cooling package, engine, PTO, and hydraulic pumps) which provides excellent accessibility to major components, low noise levels in the cab, and reduces labour hours when it comes time for planned overhaul.”
The PC2000-11 is expected to increase productivity by up to 12% while the redesigned hydraulic system monitors work equipment loads and optimises hydraulic flow based on operating conditions. The excavator is equipped with selectable working modes to tailor machine performance to application requirements. Increased engine power and new engine pump control logic give the PC2000-11 faster cycle times, the company adds.
According to Komatsu, the KomVision machine monitoring system increases operator awareness of haul trucks and light vehicles entering and leaving the working area. The seven-camera system provides a 360-degree bird’s-eye view of the working area on a dedicated 10.4” touch screen monitor
PC2000-11 also comes with thicker boom plates and castings, strengthened track and center frames, larger diameter carrier rollers and improved hydraulic cylinder seals.
Other standard features of the new PC2000-11 include:
