Product feature: Komatsu minis

The Komatsu MR-5 range boasts many industry firsts

The Komatsu MR-5 mini excavator range incorporates Tier 4 compliant low-emission engines that also reduce fuel consumption, with a range of features that improve production and work efficiency and increase job site safety, says Komatsu.

The MR-5 range covers the PC30MR-5 (3.15–3.3 tonnes operating weight), PC35MR-5 (3.62–3.77 tonnes), PC45MR-5 (4.86–4.98 tonnes), and PC55MR-5 (5.14–5.26 tonnes), with models available in both canopy and air condition cab ROPS-compliant options.

"This new generation of mini excavators harnesses Komatsu’s unrivalled technological know-how​​ and worldwide resources to bring industry-leading customer value to this market sector," says Garth Dixon, Komatsu New Zealand’s sales manager.

"Our MR-5 range boasts many industry firsts and is packed full of outstanding new and improved features.

"These include advances in operator comfort, increased safety, improved ergonomic design, even lower fuel consumption, advances in controllability, the latest version of our KOMTRAX remote monitoring system, and the highest levels of standard specifications offered in the industry.

"Across the range, they raise the bar in terms of what customers can expect from a mini excavator," Garth says.

 "In addition to delivering far lower emissions, these new minis use between five and seven percent less fuel than their MR-3 predecessors with no loss of performance or productivity.

 "Auto deceleration and idle shut down now both come as standard for reduced fuel consumption, increased residual value, and lower service costs.


"These models have standard two-way auxiliary piping for increased productivity and machine versatility when working with attachments.

"In addition, the PC45MR-5 and PC55MR-5 are fitted as standard with a second auxiliary circuit to enable fitting of tilting hitches, thumb buckets and the like.

"And across our MR-5 range, newly developed hydraulic electronic controls—here seen on mini excavators for the first time—ensure optimised machine performance and lower fuel consumption, whatever the job," Garth says.

"This, combined with selectable working modes—a concept usually only found on larger excavators—ensure optimum matching of machine power output to job site conditions, for easier operation and reduced fuel consumption."

According to Garth, cabs on the new MR-5 range have been redesigned, inside and out, for more functionality and a new more modern look and feel. "Accessibility has been significantly improved, thanks to a new hinged door design, while a high-resolution multi-functional 3.5-inch LCD colour monitor panel, with maintenance and warning information clearly displayed, improves ease of use and ensures quick and easy troubleshooting."

A number of new features contribute to increased operator safety on the new MR-5 range.
"Our new control lever Neutral Detection System is an industry-leading safety feature that prevents accidental operation if controls are inadvertently knocked or grabbed.

"Other safety features include an engine shut down secondary switch and a seatbelt caution indicator."

As standard, all MR-5 machines sold in Australia, New Zealand, and New Caledonia are covered free of charge with Komatsu’s KOMTRAX remote monitoring system, which offers what Komatsu says is the industry’s highest levels of fleet management and support, protects against misuse, provides peace of mind against theft, and guarantees maximum efficiency and uptime.

"Our new utility excavators are designed to provide our customers with unrivalled versatility, safety and comfort as well as delivering reduced owning and operating costs," says Garth.

"They are the perfect tools for confined job site applications, across construction, utility, landscaping, and similar applications."
