Komatsu entered the compact excavator market in the mid-1990s. The company’s compact excavators have many of the same features as Komatsu’s larger excavators with the same built-in reliability and quality, including steel castings in high-stress areas such as the boom stand.
Additionally, design improvements meet customer needs such as a dozer blade for backfilling and auxiliary hydraulics to power the work tools. Komatsu currently offers six excavators in 0-8 metric ton size classes. All Komatsu compact excavators meet Tier 4 Final requirements without the use of selective catalytic reduction (SCR) and the need for diesel exhaust fluid (DEF).
The smallest excavator is the PC30MR-5 and the largest is the PC88MR-10. Smaller machines (PC30MR-5 and PC35MR-5) are extremely versatile due to their light weight, sufficient power and a wide range of attachments available through OEMs such as Werk-Brau.
In the 4 to 5 metric ton size class, the PC45MR-5 and PC55MR-5 offer a two-post system along with features rarely found in compact equipment such as KOMTRAX equipment monitoring, automatic idle shutdown and economy modes.
The ROPS canopy provides class-leading visibility. For harsher climates there is a cab option with provisions for climate control, defroster and radio. All four machines are designed to outperform the competition in applications ranging from landscaping and utilities to general construction work.
