Other features Komatsu’s PC88MR-8 excavator include are a significantly larger cab than on its predecessor – the same size as on the 13-tonne PC130-8 excavator – a full-size LCD monitor, and full climate-control air conditioning.
Operating weight of the standard machine is 8.42-tonnes and it is powered by a Komatsu SAA4D95LE-5 engine rated at 49kW.
According to Steve Haines, Komatsu New Zealand's national sales manager, the new PC88MR-8 excavator is a major advance over its predecessor.
“The PC78 was one of our most popular machines, being a reliable, economic and productive machine in the 7 to 8-tonne class,” he says.
“With the new machine, Komatsu has brought all the advances introduced in 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.”
The five working modes are power, economy, lifting, attachments and hammers. Two track options are available: steel or Roadliners.
“The operator’s cab is equivalent in space and comfort to our larger excavators and with a noise level of 71 dBA is one of the quietest available in the industry, while all major maintenance points can be accessed from ground level,” says Haines.
Service and maintenance features include:
- Wide opening engine cover and side covers
- Side-by-side radiator and oil cooler for easy inspection
- Extended lubrication intervals
- Ground level maintenance
- Easy access to engine oil filter, engine main fuel filter, and fuel drain valve.
“These easy maintenance features are complemented by having our KOMTRAX remote monitoring system supplied as standard on this machine,” Haines says.
“This allows us to work closely with machine owners – whether fleet owners, contractors or owner-operators – to ensure that 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.”
“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.”
“For owner-operators, for whom a single machine can be responsible for their entire livelihood, we see this as being a major advantage, while for plant hirers and fleet owners, it can be a major weapon against unauthorised use or theft in poorly secured worksites,” he says.
“As with all products in our range, all components in our MR-8 range have been designed and manufactured by Komatsu to work together as an integrated whole.”
“This ensures they work efficiently together, providing optimum performance, reliability and durability,” says Haines.
