20 HYDRAULIC JIBS
20.1 Generality
The hy dra u lic jibs, fol da ble be hind the cab, are ad di tio nal bo oms, with articula-
tion and with one or more extension booms to be fit ted to the last extension bo om
of the cra ne; on request the ma nual ex ten sions 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 ob ta i ned thro ugh loc king
pins. The hy dra u lic con nec tion to the sup ple men ta ry fun ctions of the cra ne, is
thro ugh quick co u plin gs.
(!) ATTENTION (!)
War nin gs and nor ms for cra ne u ti li sa tion ap ply al so for hy dra u lic jibs u se.
(!) ATTENTION (!)
The loads shown on the capacity plates which concern the configuration
of the crane with hydraulic jib, refer to the hydraulic jib and consequently
they are the same whether the crane has its extension booms retracted
or extended.
(!) ATTENTION (!)
Warnings and norms for manual extensions are indicated at Paragraph 18.
(!) 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 han-
dling the load should have the adequate capacity and length; try to avoid
the load overturning by having one length passed through itself and the
other one through the hook.
20.2 Identification of the hydraulic jib
The model, the version of the crane, the year of construction and the serial
number are stamped on the hydraulic jib (fig. 1) in the following sequence:
L102*03*001 A = model
B = year of construction
A B C C = serial number
