Features :-  Komatsu Excavators  -  PC78US-6

The PC78US is a powerful excavator in an ultra compact package. Featuring a fast, if not the fastest swing cycle in its class, the PC78US offers high productivity, efficiency along with ultra compact dimensions. Accessibility to hard to reach areas is minimized because of the tight tail design of this excavator. The rigid boom offers unmatched power and makes tough jobs easy and attainable.

Powerful Engine With Turbocharger The engine can meet the EPA Tier 2 emissions regulations.
Powerful swing strength increases work efficiency on slopes.
Two working modes give a choice between extra workload and low fuel consumption.
Extended continuous operation is achieved by a high-capacity fuel tank.
PC78US-6’s superior traveling performance also provides higher productivity.
Back fill blade The PC78US features a standard back fill blade that can quickly and conveniently fill trenches and clear up jobsites.
New pressure-compensated CLSS hydraulic system HydrauMind.Even when 2 or more actuators are operated simultaneously, the PC78US-6's pressure compensated CLSS system ensures that each actuator works according to its control input without affecting the size of the load. This gives the operator precise control at all times.
Engine speed sensing=Optimum Power. Power utilized by main pump is adjusted automatically in accordance with the engine speed. That means this computerized system keeps engine speed even under high load condition.
Round form uses Tight Tail and Forward Facing Design 
Amazing Round Shape Offers the Same Balance and Control. Although, the PC78US seems smaller, the excavator still offers the same Komatsu balance, control and power of conventional machines. Another advantage of the rigid boom PC78US besides the power is the forward facing cab. The operator always has a direct line of sight to the bucket, which increases precision, confidence and productivity.
