Kobleco’s new 50 tonne excavator reaches a higher stage of efficiency

The latest addition to Kobelco’s excavator line up, the SK500LC-9, will reach Australian shores this month, bringing with it increased power, enhanced fuel efficiency and a larger, safer cab.

Kobelco Australia General Manager Doug McQuinn says the new 50-tonne excavator model is already attracting interest.“The first two units will arrive in Australia in June and will be available for sale through our dealer network. We are already fielding enquiries from customers and we expect early orders,” he says.

The new model features a Hino P11C-VC six-cylinder common rail engine that delivers 10 per cent more productivity and better fuel efficiency than the previous model, the SK480LC-8.

“The Tier 4A Hino engine in the SK500LC-9 uses an EGR cooler which helps combustion and the inclusion of a DPR filter results in reduced emissions into the environment,” Doug says. “Meanwhile, more engine torque and ‘intelligent’ hydraulics give you faster cycle times to get more work done.”

The new machines will feature Kobelco’s familiar H-mode and S-mode options for heavy-duty and standard work, along with a new ECO mode. “ECO mode delivers fuel savings of up to 13 per cent and increases the work volume per litre of fuel by eight per cent. Compared with earlier models, the latest unit also gives 5.4 per cent higher engine power output and a maximum torque increase of five per cent.”

Doug says that in addition to the improved productivity, the new model offers enhanced safety and comfort. “The new cab has rollover protection and is certified to 56,000 kg to cater for large front attachments. The cab has falling object protection (FOPS) and its roomy dimensions make it comfortable for operators as well as offering plenty of storage space.

“The cab is designed for minimal vibration and is pressurised to eliminate dust. You get excellent rear visibility thanks to the low engine cover and a wide-angle rear view camera that comes standard.

“Kobelco’s Intelligent Control System recognises the operator’s moves and assists by providing power when and where it is needed. Cushioned transitions between functions reduce jerkiness during high speed movements.”

The new model features a seven inch colour monitor with easy-to-read controls and a sophisticated attachment mode that allows the operator to program 10 different flow and pressure settings to accommodate a wide variety of attachments.

The SK500LC-9 is a robust excavator with an operating weight of almost 50,000 kg – significantly heavier than earlier models. “The long, beefy X-frame provides excellent stability and balance,” Doug says. “The model also features a high capacity hydraulic system that can be adjusted from inside the cab and two auxiliary hydraulic modes that let you switch between one-way and two-way flow, again without leaving the cab.”

A full selection of buckets and couplers are available to maximise the versatility of the SK500LC-9.

“With its fuel savings, huge power, intelligent hydraulics and enhanced operator safety and comfort, the SK500LC-9 will meet the needs of Australian heavy equipment operators,” Doug says.
