Komatsu releases two new hydraulic excavators in North America
The two machines both feature a tight tail swing radius, swing booms and convex sliding doors that hug the machine to help the excavator work in tight spaces.
The new excavators use less fuel than their predecessors with 2.19 liter, 38 horsepower, EPA Tier 4 final-classified engines. Those modifications give the new PC45MR-5 and PC55MR-5 a 5 percent boost on fuel efficiency with no loss in performance or productivity.
“The PC45MR-5 and PC55MR-5 are designed for versatility, maneuverability, comfort and low operating costs,” Kurt Moncini, Komatsu America's product manager, said. “For most confined-area job sites with construction, utility, landscaping or similar applications, this is the right tool for the job.”
The new engine has an after-treatment system that requires no diesel exhaust fluid. The Komatsu diesel particulate filter and other after-treatment components are designed to work together with the engine for added efficiency and long life.
The excavators are equipped with other amenities including enhanced working modes that allow operators to match engine speed and pump delivery to the job at hand. The machines are pioneering new work technologies with the KOMTRAX telematics system that provides key machine metrics including fuel level, operating hours, location, cautions and maintenance alerts.
