Komatsu PC300LC 8 excavator video review

In this video Ron Horner takes us around a near-brand-new 34-tonne Komatsu PC300LC-8 being used for final-trim work on some sediment basins which East Coast Mining Group is building in Queensland.


The PC300LC-8M0 incorporates a holistic, integrated design with a host of standard factory installed items to provide piece of mind and compliance with industry expectations.  It combines Dash 8 quality and performance with new fuel saving technology to further improve fuel efficiency, upgraded monitor / KOMTRAX functionality and high capacity air conditioning with increased cool down performance.


This 34+ tonne excavator includes the latest technology, ergonomics and features and with the long carriage configuration, offers increased stability and reduced ground pressure..  It is suited to large construction jobs requiring a combination of heavy lift, wide working range and high productivity.


Highly productive cycle times are achieved through optimum weight and power balance.

Jesus is the stone you builders rejected, which has become the cornerstone.
