Komatsu launches upgraded 50-tonne hydraulic excavator

Komatsu has introduced a new version of its 50-tonne PC490LCi-11 hydraulic excavator to the Australian and New Zealand markets, which features the latest technology to help operators be more efficient and accurate on site.

Designed for construction, quarrying and demolition applications, the PC490LCi-11 has 268kW of horsepower and is Tier 4 emissions certified. Its bucket capacity ranges between 1.45 to 2.7 cubic metres.

“The PC490LCi-11 is built for high production jobs. It’s durable, productive, and most importantly smart,” said Komatsu Australia’s Executive General Manager for Construction, Dean Gaedtke.

“We’ve been looking forward to bringing this updated model to our Australian and New Zealand customers for some time, and we know they’ll definitely see the benefits of adding it to their fleets.”

A key feature of the upgraded machine is Komatsu’s iMC 2.0 technology which helps operators work smarter and more efficiently. iMC 2.0 features a number of performance improvements from the original version released in 2016.

“iMC 2.0 uses Komatsu’s unique sensor package and 3D design data loaded in the control box to accurately check your machine and bucket position against the target, helping minimise over-excavation,” Gaedtke said.

“It’s an integrated, intelligent and innovative feature that makes every pass count for operators.

“Our research shows that iMC has helped save operators up to 63 per cent of time on site, with iMC helping reduce staking, grading and inspection with its 3D design data and semi-automatic grading.

“Accuracy is also improved by up to 33 per cent, with iMC providing the ability to continuously monitor your grade and semi-automatics dig precisely to grade.”

The PC490LCi-11 is also equipped with features that boost performance and productivity while reducing operating costs, Komatsu said.

“There are two boom mode settings, which provide power mode for maximum digging force or smooth mode for fine grading operations. Plus, large displacement high efficiency pumps provide high flow output at lower engine speed, improving machine efficiency,” Gaedtke said.

“Komatsu’s Auto Idle Shutdown option helps reduce non-productive engine idle time and reduces operating costs, and new engine and hydraulic control technology in this model improves operational efficiency and lowers fuel consumption by up to 11 per cent.”
