A tight tail swing excavator is ideal for urban environments and confined spaces
For work on roadways, bridges, urban areas, or anywhere space is limited, contractors need an excavator designed for confined spaces. Komatsu’s tight tail PC78US-11 provides an ideal combination of performance and versatility in a compact and easy-to-transport package.
Efficiency and versatility come standard
With standard high flow auxiliary hydraulics and proportional joysticks that offer incredible job versatility, the 67.7 HP (50.6 kW) PC78US-11 provides precise attachment control. Its standard 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.
Faster cycles and custom modes
Its faster boom up/swing speed, combined with responsive quick arm speed, is designed to make excavating and leveling work easier and more efficient with the PC78US-11. The six working modes allow operators to tailor the machine to the required tasks, whether for fuel savings or performance.
Fuel efficient, low-cost power
The new high-efficiency power package and viscous fan clutch on the PC78US-11 work to lower overall fuel consumption by up to 13%. Its smart, simplified catalytic system removes soot without a diesel particulate filter, lowering maintenance costs and cost of ownership.
Quick and easy maintenance
Large service access doors and grouped service points with ground-level access make periodic maintenance accessible and efficient.
Maximum operator comfort
Operators work in a quiet, climate-controlled cab featuring an air suspension seat, Bluetooth radio, and high-resolution monitor with rearview camera. The sliding cab door of the PC78US-11 makes entry and exit easier in confined spaces and LED lights provide excellent vision at night.
