Marubeni-Komatsu makes it a double with new machine launch

The PC80MR-5

MARUBENI-Komatsu has launched two new products in the shape of the PC80MR-5 midi excavator and the PC228US-11 short tail excavator.

The PC80MR‐5, designed for tight spaces, has an integrated counterweight and tight tail swing radius, a swing boom that “hugs” the machine and operating weights ranging from 8,000 to 8,240 kg.

Powered by an electronically controlled Komatsu 4D98E‐5SFB Stage IIIB engine, with DPF, the manufacturer said this “more environmentally‐friendly” engine maintains the performance of the previous series while reducing fuel consumption by up to 10%.

“The PC80MR‐5 is designed for improved versatility, manoeuvrability, comfort ‐ and for low operating costs,” said Emanuele Viel, KEISA group manager utility. “It’s a perfect tool for most confined‐area jobsites and for construction, utility, landscaping or similar applications”.

The auto decelerator and idle shutdown both come as standard, while newly developed hydraulic electronic controls are said to optimise machine performance and lower fuel consumption. There are six selectable working modes.

The cab has also been redesigned, with a hinged door solution aiding access and a high‐resolution 3.5” LCD colour monitor panel. Air conditioning is standard.

The new PC228USLC‐11 ultra‐short tail excavator is described as bringing advances in lifting performance with 6% lower fuel consumption, improved operator comfort, increased safety features and low noise levels. Its rounded cab design allows it to rotate within the counterweight’s swing radius.

Paul Dickinson, product manager at Komatsu Europe International said, “This new ultra‐short tail excavator does so much more than simply meet EU Stage IV emission regulations: it offers significant advances in fuel consumption, lift capacity and working envelope, provides 3G communications, improves operator comfort and includes new safety features. The new larger diameter boom raise cylinders provide much improved lifting capabilities and with the improved hydraulics, smoother operation and levelling.”

Operating weights range from 23.600 kg to 24.150 kg. It is powered by an EU Stage IV emissions‐certified Komatsu SAA6D107E‐3 engine.

All major components, including the engine, hydraulic pumps, motors, and valves are designed and produced by Komatsu.

The manufacturer said larger boom raise cylinders, combined with an upgrade to the arm’s hydraulic circuit, improve lift capacity by up to 21%.

The ROPS‐certified cab features a reinforced box structure framework. It is mounted on rubber isolation dampers for low vibration levels.
