Yanmar have launched the ViO57-6, an upgrade of the popular ViO57 series.
This zero tail swing excavator in the 6 tonne weight class has seen many upgrades which will; improve performance, increase user comfort, reduce service times and ultimately lower overall cost of ownership.
The standard long arm boom still offers a dig depth of over 4 metres and 4420 mm dumping height. However the design has been re-modelled. The new design with a box structure has not only reduced the weight of the structure by 40kg but also increased lifting capacities by 10%. This design is more robust and durable too, decreasing likelihood of machine damages and downtime.
All cylinder tubes and rods still have the highest levels of protection thanks to a spring type steel plate covering them.
The ViO57-6 benefits from an improved powerline: the combination of the new more powerful Yanmar engine and hydraulic pump, gives 14% more power and a new control valve improve the cycle-times by more than 10 %.
The 48.4 HP TNV engine is equipped with direct injection to create clean burning power. It has fully-electronic control to provide the ViO57-6 with total intelligent engine control. It is equipped with a turbo charger improving power, fuel efficiency and torque. This choice allows to reduce the rpm by 200 rpm and improves drastically the noise level for the operator and the bystanders.
The ViO57-6 is also equipped in standard with an Eco mode which effectively controls the motor speed, reducing it by 300 RPM, thus allowing a very low fuel consumption. The Auto-Idling device, also as standard, enables the engine to drop back to idle if the operator doesn’t touch the operating levers for 4 seconds. Environmental performance (noise and emissions) and fuel consumption are even more improved.
Further standard equipment in the ViO57-6 includes two auxiliary hydraulic circuits. Both are operated via a proportional control located on the joystick which adapt the flow and the direction of the oil flow. Additionally each circuit has an easy-to-operate potentiometer which adjusts the oil flow to the optimal requirement for each and every attachment.
Finally the ViO57-6 design provides an ergonomic environment, excellent visibility and exceptional safety. The improved shape of the cabin provides the operator with an optimal 360° visibility in order to improve the safety on the jobsite and to make work more efficient. The door is now a single piece rather than the older split opening design, making damages less likely. Yanmar have installed an air suspension seat that has numerous possibilities of adjustment to give the optimal seating position. The instrumentation panel has been redesigned as well as the armrests, which further enhance the operator’s comfort.
