PC490LC-11 Excavators

Now powered by Komatsu’s low emission Tier 4 Final-compliant engine technology, our 50 tonne PC490LC-11 is designed for heavy duty construction and quarrying applications.  Featuring a heavy duty, reinforced undercarriage, larger counterweight and enhanced power mode, the PC490LC-11 delivers high productivity and lower owner and operating costs. As with all our construction excavators, key components are designed and manufactured by Komatsu to work together in an integrated package. And it comes standard with our KOMTRAX remote monitoring and location system, backed by our NZ-wide service and support network.

  • 268 kW / 359 HP
  • 48,690 kg
  • 2.7 m³

Enhanced Productivity

Enhanced power mode with increased hydraulic flow provides up to 13% improvement in productivity.

Super Stability & Durability

Heavy duty, reinforced undercarriage and larger counterweight provide high lift capacity, lateral stability and added durability.

Comfortable Working Space

The wide spacious cab includes a heated air suspension seat with reclining backrest. The seat height and position are easily adjusted using a pull-up lever. The armrest position is easily adjusted together with the console. Reclining the seat further enables it to be fully laid back with the headrest attached.
