Komatsu introduces tight-tail excavator

Komatsu’s tight-tail excavator, PC78US-11, provides an ideal combination of performance and versatility in a compact and easy-to-transport package, for work in urban environments and anywhere space is limited. 

With standard high-flow auxiliary hydraulics and proportional joysticks that offer incredible job versatility, the 67.7-horsepower PC78US-11 provides precise attachment control. Also standard, a grading blade with new moldboard profile, improves backfilling and light grading efficiency. The conventional boom design has a greater raising angle to reduce front bucket swing radius.  

Its faster boom up/swing speed, combined with responsive quick arm speed, is designed to make excavating and leveling work easier and more efficient. PC78US-11’s six working modes allow operators to tailor the machine to the required tasks, whether for fuel savings or performance.  

A new, high-efficiency power package and viscous fan clutch work to lower overall fuel consumption by up to 13 percent. Its smart, simplified catalytic system removes soot without a diesel particulate filter, lowering maintenance costs and cost of ownership.

In addition, large service doors and grouped service points, with ground-level access, make periodic maintenance accessible and efficient. 

Komatsu develops and supplies technologies, equipment and services for the construction, mining, forklift, industrial and forestry markets. The company's global service and distributor networks support customer operations to enhance safety and productivity, while optimizing performance.
