Now powered by a new technology Komatsu engine, our PC490LC-11 is designed for heavy construction, quarrying and demolition applications, delivering high productivity and lower owning and operating costs. PC490LC-11SE also available. 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 Australia-wide service and support network.
Resources
Features and benefits
Enhanced productivity
Enhanced power mode with increased hydraulic flow provides up to 13% improvement in productivity.
Super stability and 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.
