4.14.6.4 Mounting of cranes on Unimog´s
For the attachment of cranes on the Unimog it is necessary to install
a sub frame above the Unimog chassis fame. Crane mounting, even
in case of small cranes, without a sub frame is not permitted and will
cause vehicle damages. The sub frame must be dimensioned ac-
cording to section 4.14.4, page 123.
The crane mounting frames on common trucks are attached to the
frame with U-bolts or other clamping devices. These mounting
methods cannot be used on Unimog´s and will cause damages to
the chassis frame. Use only the fastening brackets and plates, which
are recommended in this Unimog mounting guideline.

The following key facts must be considered for mounting of cranes
on Unimog´s:
•
GVW and maximum axle loads
•
Minimum axle loads
•

Mounting positions of cranes
Cranes can be mounted on three different positions on the Unimog:
•
Front mounting of cranes:
o
Cranes up to 20 mt can be mounted directly behind
the cab.
o
Advantages: Trailer use possible, Mounting of plat-
forms possible
•
Center mounting of cranes:
o
Cranes up to 30 mt (in special cases up to 40 mt) can
be mounted on the center of mounting frame.
o
Advantages: Plenty of space between the cab and
the crane
•
Rear mounting of cranes:
o
Cranes up to 16 mt can be mounted at the rear of the
vehicle.
o
Advantages: Quick attach and detach possible, tilt
able crane attachment possible and allows trailer use,
mounting of a platform possible
All three mounting positions are located behind the cab. The differ-
ent positions are shown in the following figures.
