Unique features on new zero-swing minis

A new range of three Komatsu MR-2 zero-swing mini excavators, incorporate features not seen on other machines, the company claims.

These include:

A two-post ROPS canopy (unlike the four-post canopies on all other mini excavators). These provide benefits over the four-post configuration by providing greatly improved visibility and walk-through access from either side

A large cab, equal to that on a 20t PC228-6 excavator, for the cab options

a tilting operator station (cab and canopy versions), along with fully opening engine hood and side covers for unprecedented access;

lower centre of gravity; and

A cast X-frame for increased strength and reduced mud and debris build-up. on the The three machines are the PC30MR-2, PC40MRX-2 and PC50MR-2.

They replace the original MRX range, which has been in production for the past four years.

According to Dave Stuart, Komatsu Australia's group manager, utility products, the range builds on the strengths of the MRX which had established a reputation for reliability, durability and productivity.

"The tilting operator's station has allowed us to significantly condense the space taken up by the engine, hydraulics and other components, giving a much larger operator's area while giving unprecedented access to major components.”

Other major features include:

additional counterweight on the Australian builds, for more stability, digging power and lifting ability;

automatic two-speed travel, automatically adapting travel speed and torque to the underfoot conditions;

use of Komatsu's HydrauMind hydraulic system, the same one used on its larger excavators

a pattern change valve so the controls can be set to the operator's preference;

options, including bolt-on road liners and a power-angle-tilt (PAT) blade; and

large-capacity air conditioning as standard on the cab versions.
