2018 has been a year full of celebrations for the Japanese excavators’ producer company Yanmar. The 50th year from the presentation of the first diesel self-powered mini excavator and the launch of the new zero-tail-swing ViO miniexcavator have been recently celebrated; years ago, as today, Yanmar is at the vanguard of the buildings machineries R&D sector. Yanmar ViO models are 4 among 2,5 and 3,6 tons: the perfect dimensions for working in small and tight areas. At Bauma Munich 2019 Yanmar will present the new generation gas-powered engines: 4TN88G and 4TN-9G.
Despite the compactness of ViO26-6, ViO27-6, ViO33-6 and ViO38-6, the idea of Yanmar is to increase the comfort of the operator with bigger spaces and higher security levels, new technologies, better ergonomics and the loudness has been fully restricted in the cockpit; the concept of “Universal Design” is so born and also the ideal positions of joysticks and levers are become relevant.
These Yanmar rubber tracked mini excavators present very high and precise performances despite their dimensions; indeed, high quality components of the power train are used, as the new TNV Yanmar engines for example, which ensures safer and cleaner emissions and favorable consumptions of fuel.
The new models of the ViO-6 selection differentiate one from the other thanks to the hydraulic system used:
- Yanmar ViO26-6 uses a Flow sharing system. Through a unique pump and a pressure compensated supplier proportionality and fluidity of the movement are ensured.
- Yanmar ViO27-6, ViO33-6, ViO38-6 use a Vipps system (ViO Progressive 3-Pump System), a particular distributor that accumulate the flow rate of the pumps (4 hydraulic pumps: 2 variable displacement pumps and 2 gear pumps) obtaining combined faster and more fluid movements.
