Rig the outrigger span 7.98 x 8.50/1.00 m (26.1 x 27.9/3.3 ft)

Risk of damage to the suspension struts and tyres!
Always extend the auxiliary supports before you perform one of the list
processes.
This prevents the suspension struts and tyres from becoming overloaded
and damaged.
Loads of up to 55.7 t (122,789 lbs) can arise on the outrigger pads of the
auxiliary supports when the truck crane only stands on the supports. If
the ground cannot support these loads, you must determine the required
support area and install the supports.

6.6 Installing/removing the supporting box
With this outrigger span, the truck crane is sta-
bilised at the front to an outrigger width (2)
8.50 m (26.1 ft). The auxiliary supports must be
extended at the rear. This produces the outrig-
ger span (3) of 1.00 m (3.3 ft) and the outrigger
length (1) of 7.98 m (26.1 ft).
You must rig this outrigger span before:
– Slewing the superstructure with the rear
supporting box removed,
– Removing/installing the supporting box,
– Installing / removing the rear bumper,
– Setting down the main boom on a separate
trailer, or raising the main boom from
a trailer.
