Komatsu
Half a Dozen Mini Excavators Made to Meet Customer Needs

Komatsu entered the compact excavator market in the mid-1990s. With many of the same features as Komatsu’s larger excavators, the company’s compact excavators have built-in reliability and quality, including steel castings in high stress areas like the boom foot. Komatsu’s compact excavators have been designed to meet customer needs by including a dozer blade for backfilling and auxiliary hydraulics for powering attachments.

Currently, Komatsu offers six excavators in the 0- to 8-metric-ton size classes. All of the compact excavators meet Tier 4 Final requirements without using selective catalytic reduction (SCR) and without the need for diesel exhaust fluid (DEF).

Komatsu says its smallest excavators, the PC30MR-5 and the PC35MR-5, are versatile because of their light weight, ample power and large range of work tools available through OEMs such as Werk-Brau.

The PC45MR-5 and PC55MR-5, which are in the 4- to 6-metric-ton size class, offer features rarely found on compact equipment, says Komatsu, including KOMTRAX equipment monitoring, auto-idle shutdown and economy modes, as well as a two-post ROPS canopy, for class-leading visibility. For harsher climates, Komatsu offers a cab option with climate control, a defroster and provisions for a radio.

The PC78US-10 takes the compact line a step further by offering a 7-ft, 5-in. arm with a setback boom, excellent for working in confined spaces. The PC78US-10 extends only 9 in. from the tracks at the rear for maneuverability. Advanced features such as closed-center load sensing hydraulic system (CLSS), a variable flow turbo and enhanced working modes means the PC78US-10 is up to 3 percent more productive than the previous model. There is also a standard two-way blade available and an optional 8-ft, 1-in.-wide blade, when equipped with the wider 24-in. triple grousers.

Finally, Komatsu’s PC88MR-10 is an 8.5-metric-ton excavator with a swing boom and true tight-tail performance. Similar to smaller excavators, the PC88MR-10 features booms and arms constructed with thick plates of high-tensile-strength steel and piping for optional attachments such as thumbs and hammers.

You want to choose a machine that will stand up to many jobs.”
