New Yanmar ViO50-6B
The 4,855kg Yanmar ViO50-6B zero tail swing mini-excavator is powered by a Stage 5-compliant Yanmar 4TNV88C-PBV engine with cooled exhaust gas recirculation (EGR), diesel particulate filter (DPF) and upgraded powerline. Gross power is 28.3kW and torque 144Nm. With a bucket digging force of 36.5kN and traction force of 42.7kN, the ViO50-6B delivers impressive performance even in the tightest spaces, while Eco Mode and auto deceleration come as standard.
The model is fitted with Yanmar’s VIPPS hydraulic system, which features an aggregated power regulator, fitted with two variable flow piston pumps and a multiple combination directional control valve. This increases work speed and allows both smooth and simultaneous operation – even when on the move. Thanks to a X-shaped box section undercarriage, the ViO50-6B is said to have excellent torsional stiffness. Meanwhile, Yanmar has worked to optimise weight distribution and increase stability, while upgraded components improve durability and increase service intervals.
The cabin has an adjustable air suspension seat, and a 3.3-inch digital interface is integrated into the right console, which provides real-time machine data including fuel consumption, coolant temperature and service intervals. To ensure simple servicing, the ViO50-6B features an easy-open engine bonnet, with the right side cover mounted on a single hinge to give easy access to major components. A new boom design, with what Yanmar calls best-in-class all round cylinder protection, further reduces maintenance requirements and dramatically reduces total cost of ownership.
