Power hydraulics (circuit III and IV)
The power hydraulics allow rotating consumers to be powe-
red (e.g. cutting roller, wood chipper etc.). Both circuits are
designed as open circuits with a maximum pressure of 280
bar. Code HL4 includes one circuit while code HL5 includes
two power hydraulics circuits.
The power hydraulics are located in the platform intermedi-
ate frame and can be removed if necessary (e.g. for winter
service operations). They are powered by a propeller shaft on
the engine power take-off, code N05. The hydraulic couplings
are located at the vehicle rear above the end crossmember.
Front hydraulic connections are also optionally available, eit-
her for one circuit or for both circuits.
System concept of new hydrostatic drive G34:
The new hydrostatic drive system: code G34 combines a
modified hydrostatic drive major assembly concept with the
cruise control operating and control concept. The previous
hydrostatic drive system (code G33) has now been superse-
ded with the launch of the new BlueTec 6 Unimog implement
carrier. The new hydrostatic drive (code G34) allows fully hy-
drostatic driving at up to 50 km/h and, in combination with
EAS, also allows mixed hydrostatic/transmission-powered
driving and can be controlled with the normal driving controls
(accelerator pedal, brake, gear selector lever, steering wheel
cruise control buttons). In addition, the gearshifting, cruise
control and travel direction functions are supported by a left
additional control lever (code DG1). The vehicle can also be
accelerated and decelerated via the hydraulic joystick in "dri-
ving joystick active" mode.
Modified suspension
The capabilities of the suspension have been retained in their
entirety and continue to underline the advantages of the Uni-
mog concept.
•
Weight optimization measures: Cutouts in the frame, use
of high-strength steels, greater proportion of light alloys
and plastics
•
The portal axles have also been reinforced which means
that the permissible gross vehicle weight is above the
previous level
•
The additional major assembly weight has been overcom-
pensated for with additional components
•
Pneumatic disk brakes on model series U2xx/U3xx
Standardized mounting points
On the current Euro V model series of the Unimog implement
carrier, mounting points were defined which have proven ef-
fective across all areas of usage. The new Unimog generation
will continue to use these standardized interfaces and dimen-
sions. This applies to the front mounting plate, front power
take-off, the ball mounting points on the platform and the
mounting brackets at the rear end.
Improved ergonomics
•
Steering column with adjustable height and inclination
(not on vehicles with transferable steering)
•
Reduced steering wheel control force and steering capa-
bility at standstill
•
Multifunction steering wheel
•
Improved cab steps
•
Transmission control via right multifunction control lever
•
EQR operation on hydraulics joystick
•
Engine speed adjustment function
•
Driving and function controls within primary
(400 mm - 600 mm) area of reach of driver
•
Modular positioning of hydraulics joystick
•
Hydraulics joystick within optimal reach area
•
Improved accessibility of switches of center console
