The improved vehicle control contributes to increased productivity while maintaining low fuel consumption.

Up to 3% increase in productivity.

(Compared to the PC78US-8)

Up to 2% increase in drawbar pull compared to previous models.

A blade for efficient back-filling and leveling work is equipped as standard. The dedicated pump for the blade enables smooth dozing operation.

Short Implement Swing Radius
12' 2" (3710 mm) boom raising angle of the PC78USLC-10 is larger than a conventional profile excavator. The result is reduced front implement swing radius.

Tight Tail Swing Radius
4' 7" (1390 mm) short tail swing radius of the PC78USLC-10 allows the machine to work in more confined areas than a conventional machine.

Round Profile of Both Front and Rear Portion of the Upper Structure
Komatsu tighttail hydraulic excavators allows the machine to work in surprisingly tight quarters. 

The new Komatsu Diesel Oxidation Catalyst (KDOC) has an integrated design that does not interfere with daily operation. This smart and simplified system removes soot using 100% "passive regeneration" without the need for a Diesel Particulate Filter. The KDOC is a simple design and does not have a scheduled service interval like a DPF and is designed for long life with no scheduled maintenance required. For owners, this means lower owning and operating costs due to less complexity and seamless operation.
