New 8t excavator from Komatsu

The new 8.4-tonne machine, the PC88MR-8, replaces the PC78MR-6 and incorporates a significantly larger cab than on its predecessor – the same size cab as on the 13-tonne PC130-8 excavator.The new machine is powered by a Komatsu SAA4D95LE-5 engine rated at 49 kilowatts and includes five working modes: power, economy, lifting, attachments and hammers.“The [outgoing] PC78 was one of our most popular machines, being a reliable, economic and productive machine in the seven to eight-tonne class,” Komatsu Australia national sales manager Carl Grundy said. “With the new machine, Komatsu has brought all the advances introduced with the Dash-8 construction line into a compact sub-10 tonne excavator.“These include auxiliary hydraulics – including hammer piping – as standard, five working modes, and automatic two-speed travel.” Grundy said the KOMTRAX remote monitoring system was supplied as standard on the new machine and allows Komatsu to work closely with machine owners to ensure their machines remain in optimum operating condition at all times, with early warning of any potential issues or component failures.“We are able to alert owners, plant managers or operators to any unusual occurrences, allowing them to carry out preventive maintenance before unscheduled downtime occurs,” he said. “And the other great advantage of KOMTRAX is that it makes these machines virtually theft-proof, as we are able to track the location of all KOMTRAX-fitted equipment – and prevent it being started or used if it is reported stolen.”
