Komatsu Introduces New Hydraulic Excavators

Komatsu America introduced the new PC45MR-5 and PC55MR-5 hydraulic excavators, two machines with tight tail swing radii, swing booms and convex sliding doors that hug the machine to help with work in tight spaces. Featuring 2.19 liter, 38 horsepower, Tier 4 final, 4D88E-7 engines, the new machines use up to five percent less fuel than their predecessors with no loss to performance or productivity, the company says.


PC55MR-5-action-tight“The PC45MR-5 and PC55MR-5 are designed for versatility, maneuverability, comfort and low operating costs,” said Kurt Moncini, Komatsu America product manager. 

The new Tier 4 Final engine has an after-treatment system that requires no diesel exhaust fluid (DEF). The Komatsu diesel particulate filter (KDPF) and other after-treatment components are designed to work with the engine for added efficiency and long life.  

The PC45MR-5 and PC55MR-5 excavators also feature

  • Enhanced working modes that allow operators to match engine speed and pump delivery to the application.
  • Wide service doors for easy-access, ground-level maintenance.
  • A high-strength, X-track frame that deters dirt and debris buildup, saving operators valuable machine clean-up time.
  • A tilt-up cab for easy access to hydraulic components and the back of the engine.
  • New auto-idle shutdown and economy modes help save fuel and reduce machine wear.
  • ROPS and OPG Level 1 certified cab and canopy options provide a durable, secure operator work environment.
  • KOMTRAX telematics system and monitor provide key machine metrics, including KDPF status, fuel level, operating hours, location, cautions and maintenance alerts.
  • New 3.5 inch, high resolution LCD monitor with Ecology Guidance helps operators monitor machine performance to maximize fuel efficiency.
  • Standard auxiliary piping for attachments and thumb mount provision on the arm provide job versatility in applications ranging from digging to demolition work, grabbing scrap to laying sewer pipe.
