L4 HYDRAULIC JIBS
The hydraulic jibs, foldable behind the cab, are additional booms, with articulation
and with one or more extension booms to be fitted to the last extension boom of
the crane; on request the manual extensions can be installed on the extension
booms of the jib.

NOTE
The weights reported in the table are indicative and can vary in relation to the
fittings.
The jibs are fitted by means of the insertion of the extension connecting boom
into the crane extension boom; the fixing to the crane is obtained through locking
pins. The hydraulic connection to the supplementary functions of the crane, is
through quick couplings.
(!) Warnings and norms for crane utilisation apply also for hydraulic jibs use.
(!) Warnings and norms for manual extensions are indicated at Paragraph L1.
(!) ATTENTION (!)
It is recommended to employ lifting means adequate to the weight of the load and
radius of the extensions; during this operation
the operator is responsible for the
machine safety
.
The slings or the cables used for handling the load should have the adequate
capacity and length; try to avoid the load overturning by having one length pas-
sed through itself and the other one through the hook.
L4.1 Identification of the hydraulic jib

number are stamped on the hydraulic jib (fig. 28) in the following sequence:
L102*03*001 A = model
B = year of construction
A B C C = serial number
