COMPACTNESS
ViO50U
The ViO50U is a true Zero Tail Swing machine: neither the
counterweight nor the front part of the upper frame exceed the
width of the crawlers.

Min. front swing radius:

2,220 mm

Design principles:
> No rear overhang.
> Front swing radius with boom swing: 1,800 mm.
> Rear swing radius: 975 mm.
> Overall width of the machine reduced to 1,970 mm.
> The curve of the boom has been redesigned to
facilitate loading and unloading of trucks.

Rear swing
radius:
975 mm

Front swing radius with boom swing:

1,800 mm

No rear
overhang

> Side ditch digging up to the wall with nothing sticking

out beyond the track.

Width: 1,970 mm

Advantages for the user:

> Possibility to work in narrow areas, where a
conventional machine is not able to work.
> Possibility to work along a wall.
> No dead angle in the upper structure: maximum
all-around visibility.
> Safety and productivity for the operator.
> Operations are perfectly adapted to urban
areas: the machine does not obstruct all lanes
of trafc.

2,785 mm

> For increased productivity the blade has been put

forward by 20 cm. This allows better control of the
job and better levelling. The blade lever, formerly cable
operated, is hydraulic.

HIGH PERFORMANCE
ViO50U
Combining long experience and unrivalled expertise, YANMARs
technology ensures environmental performance and high
efciency.

VIPPS hydraulic circuit (ViO Progressive

3 Pumps System)

A high-power, eco-friendly engine meeting the

European Comission emissions regulations

Hydraulic circuit tted with a variable-ow

dual piston pump, a gear pump and a multiple
combination directional control valve:

The YANMAR TNV direct injection diesel

engine was built for clean emissions and
powerful output. With its improved fuel
injection system, it meets the emissions
regulations of the European Comission (EC)
and the US Environmental Protection Agency (EPA).
Its quiet operation makes it both people- and planetfriendly.

> Increased working speed due

to the cumulative
pump capacities.
> Smooth, simultaneous operation
of all functions,
even when travelling.

Boom x Arm

> Perfect combination of the Yanmar engine and the

hydraulic system for reduced fuel consumption.

Hydraulic PTO plumbing, supplied as standard

equipment, for working with a variety of attachments.
> Extension of the 3rd circuit with 2 additional
valves for the use of clamshell buckets or other
attachments.

> The 3rd circuit of the hydraulic system is proportional in standard: easy
use of accessories.

> Extension of the 3rd circuit.

Exceptional stability and lifting strength

The combination of a wide counterweight,
asymmetric crawlers (system patented by
Yanmar VICTAS), and excellent weight
distribution provide the ViO50U with an
impressive level of stability and exceptional lifting
capacities.
The VICTAS system consists in increasing the bearing
surface by increasing the track path and using asymmetric
crawlers:
> Increased lateral stability and lifting capacity.
> Reduced track wear.
> Quiet, vibration-free movement.

COMFORT
ViO50U
Operation is so easy its a joy. All-round comfort and convenience.
Large space for unrestricted operation
> Even if it is a Zero Tail Swing machine, the ViO50U
is tted with a very large cabin for this weight class,
which provides easy, unrestricted operating space.

Suspension seat in standard

> The seat of the ViO50U can be adjusted according to
the operators weight. This improves his comfort and
his work position and reduces shocks and vibrations.

Safe and ergonomic pilot system

> Perfect position of joysticks, armrests and travel levers...

Joysticks + comfortable arm rests

> Non-tiring wrist control levers are easy to grasp.
Comfortable arm rests make delicate control and long
hours of operation easier.

Other equipment: foldable footrests for ample legroom, travelling pedals, 12 V power socket, cup holder,
document box, standard electric refuelling pump....

SECURITY & RELIABILITY

ViO50U

ISO-conforming cabin with sharply enhanced rigidity for safety and condence
The cabins use of a high-strength, high-rigidity
ROPS enhances protects operator space in the
event of a rollover. It also conforms to the FOPS 1
standard for structures protecting the operator
from falling objects. This sturdy cabin lets you work
in comfort and condence.

> In raised position, the

lock lever includes engine neutral start mechanism to prevent danger
of accidental operation.

> Standard back mirror

lets operator check for
safety behind the machine and keeps others
safe.

> A work lamp built into the lower part of the boom, where it
is protected from breaking, comes as standard. With wide
angle front visibility secure, you can work with condence
at evening.

MAINTENANCE
ViO50U
Simple maintenance structure for fast and easy access wherever its needed.

> Careful routing and protection of the hydraulic pipes

on the boom and on the right side of the machine
under the step. You can remove the step to access the
sockets and change the equipment pipes.

> Easy access to all maintenance

points: engine components, lters,
pressure plugs, hydraulic pumps...

> Cylinders
completely
protected (rod and cylinder) by highly elastic
steel plates to resist any
possible shocks.

> Layout of the counterweight designed to protect the

side panels against any possible shocks. Additional
moulded parts at the left and right outer corners of the
upper frame, improving shock resistance.
