The Yanmar ViO55-5 excavator is a 5-ton excavator. Its compact design and robust construction make it a perfect choice for all types of excavation. It is powered by a Yanmar 4TNV88-PBVB water-cooled diesel engine (28.8 kWt/2,400 rpm), which achieves a balance between stable power and fuel economy.
This 5,320 kg machine is 5,560 mm long, 2,620 mm wide and 1,990 mm high (ViO55-5A) and has a 0.16 cubic meter bucket, making it ideal for working in confined spaces. The unique steering system allows for easy maneuverability even in small towns or in rural areas, while the new hydraulic system enables precise digging and leveling operations, making it the ideal choice for jobs that require precise control.
With a bucket digging force of 33.8 kN and a stick digging force of 22.5 kN, the ViO55-5 can easily handle tough jobs such as digging in hard soil or breaking rocks. Its working range includes a maximum digging radius of 6,200 mm, a digging depth of 3,980 mm and a throwing height of 4,400 mm, and it has a maximum speed of 10 rpm and a travel speed of 4.4 km/h to provide high productivity. The machine is designed with a strong steel and a good dust seal, which can work well even in harsh environments.
Low noise and good visibility from the cab greatly improve operator efficiency, while easy access to engine components simplifies maintenance. Equipped with a standard dozer, suspended seat and hydraulic breaker, the ViO55-5 combines a wide range of features and reliability for urban construction and small projects.
The Yanmar ViO55-5 is designed to perfectly match urban infrastructure and site improvement projects, reducing work time through intelligent design. The zero-reverse design eliminates rear-end drag, allowing the operator to work efficiently even near walls or in narrow roads.
