This model is a compact zero-tail excavator for buyers who need narrow-space digging, wall-side work and urban jobsites. We usually keep around 3 flowing units. Most machines are repainted, many have new track chains and shoes, and blade configuration depends on the exact unit.
Komatsu PC78US-6 is not a normal 7-ton excavator for open-field earthmoving. Its value is the zero-tail body and compact structure. It is made for narrow roads, wall-side digging, drainage work, foundations, courtyard jobs, city repair and places where a normal PC60 or PC70 cannot swing easily.
We mainly supply Komatsu PC78US-6. We usually keep around 3 flowing units. Most available machines are repainted before export. Many units come with new track chains and track shoes, but the final undercarriage condition must follow current photos and travel video. Some units have a blade, while some do not, so buyers should confirm the exact machine before quotation.
For used PC78US-6 machines, meter hours are not a reliable way to judge condition. Many machines are old, repaired or repainted, so working hours should only be treated as a reference. The real decision should come from cold start, hot-machine hydraulic response, swing, travel, offset boom condition, undercarriage and serial plate.
PC78US-6 is better for used equipment dealers, local resellers, rental buyers and contractors who have real narrow-space jobs. If the customer only wants cheap general earthmoving, PC60 or PC70 may be easier and cheaper. Do not buy PC78US only because it looks special. Buy it when the jobsite really needs zero-tail swing.
PC78US-8 may be available sometimes, but stock is limited in China. If your market needs newer emission acceptance, smoother hydraulic control or better machine image, ask us to check current PC78US-8 availability. Buyers should still confirm local import rules before purchase.

PC78US-6 is worth buying when the jobsite is narrow. The short-tail design helps near walls, roads, buildings and foundations. In open fields, PC60 or PC70 may be enough.
Many available units have new track chains and track shoes. This helps used equipment dealers show better condition, but buyers should still confirm walking video, final drive noise and undercarriage close-ups.
Most PC78US-6 units are repainted before export. Paint helps resale, but paint is not condition. Cold start, hydraulic movement, swing and travel video still decide the machine.
The value of PC78US depends on swing, offset boom pins, side cylinders and hot-machine hydraulic response. A clean photo cannot show pump weakness or swing play. Ask for working video after the machine is warm.
A cheaper PC78US-6 is not always better if the main pump, swing motor, offset boom cylinders or undercarriage need repair. Check hot-machine video before payment.
Before payment, ask for current video and photos of the exact PC78US-6 unit.
