Komatsu Australia has released the PC27MR-3, a sub-3 tonne addition to its MR-3 range and suitable for transporting on a standard 3 tonne capacity tipper.
With an operating weight of 2.89 tonnes, it is powered by an Interim Tier 4 compliant Komatsu 3D82AE-6 diesel rated at 19.2 kW, and incorporates Komatsu's KOMTRAX remote monitoring system as standard.
"This new excavator has been designed for use with 3 tonne tippers, making it an extremely versatile and easily transportable unit while still delivering close to equivalent digging power and performance to a 3 tonne excavator," said Carl Grundy, Komatsu Australia's national sales manager, utility.
As with other models in Komatsu's MR-3 mini excavator range, the PC27MR-3 incorporates a class-leading low-emission engine complying with the forthcoming Tier 4 emissions standards increased productivity, improved operator comfort and safety, and easier servicing and maintenance.
Key features include:
Higher productivity, through faster hydraulics, extended dipper arm working range and better dozing performance
A new high-strength "X-track" frame, similar to what is used on Komatsu's larger excavators, giving improved durability and reliability
Komatsu's HydrauMind CLSS (closed load sensing system), the same system used on its larger excavators and other equipment, and which gives precise control of all machine functions even when they are activated simultaneously
Easier serviceability through better service access, including a tilt-up operator's compartment, wider-opening engine door and side cover, side-by-side radiator and oil cooler for easier inspection and cleaning, and extended lubrication and engine oil replacement intervals
Improved operator safety and comfort, through such features as having the hosing on the boom sheathed to protect the operator from hot oil in the event of a hose failure, as well as the largest, most comfortable operator cab/cabins of any mini excavator range
Full ROPS cab/canopy, based around Komatsu's two-post ROPS design
Factory air conditioning on the cabin model, so it is fully integrated within the excavator and is covered by a full Komatsu factory warranty.
"As with all products in our range, all components in our new PC27MR-3 excavator have been designed and manufactured by Komatsu to work together as an integrated whole," said Carl.
"This ensures they work efficiently together, providing optimum performance, reliability
and durability.
"On the service side, Komatsu pioneered the concept of a tilt-up operator's compartment for easier access to key components, and on the PC27MR-3, this has been developed even further, with improved component positioning, ensuring that access is even quicker and easier.
"This is complemented by having our KOMTRAX remote monitoring system supplied as standard on all these machines the first time this system has been available on Komatsu utility equipment," Carl said.
"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.
"And 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," he said.
"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."
