4.13 Front mounting of implements
4.13.1 General notes to front mounting
There are two possible methods of using the front body space of
the Unimog:
•
Mounting on the front mounting plate (option code D12),
see Section 4.13.2 Front mounting plate, page 85
•
Mounting on the front mounting integrated implement sup-
port, see Section 4.13.3 Integrated implement support, page
89
When mounting implements on the front mounting plate or the in-
tegrated implement support the following items must be consid-
ered:
•
Maximum permissible front axle load
•
Axle load distribution
•
Minimum rear axle load
•
Driver’s view of vision
•
Implement front end distance (center steering wheel to the
front edge of the implement, maximum
137.79 in / 3,500 mm, depends on local regulations)
•
Implement drive
It may be necessary to mount a counterweight on the platform
and/or in the rear mounting brackets (code D50) to achieve the
required rear axle load of
at least 41% of the actual gross ve-
hicle weight for the U500 , see also Section 4.4, page 66.
4.13.2 Front mounting plate
The front mounting plate can be fixed to the integrated implement
support in two different positions. Implements on the front mount-
ing plate can be driven by the front power take-off (code N08), by
the basic hydraulics (single and/or double circuit) or by the power
hydraulics (closed or open circuit).
