Wrong manoeuvring: the crane can fall break or overturn if the operator
performs a wrong manoeuvre due to the lack of familiarity with the operation
procedures (see manual of use and maintenance) or due to inadequate psy-
chophysical conditions: we remind you that the directives in force impose a
suitable training of the personnel before using these types of machines and
require an adequate psychophysical condition to operate safely a lifting device
that always implies the intrinsic danger of a lifted load.
Weather conditions: too high or too low temperatures may damage the com-
ponents of the oleodynamic and electric circuits (See max and min conditions
of use); it is forbidden to operate the crane during a storm with lightning
hazards, so we recommend to fold it and put it to rest. Furthermore when the
wind is too strong the crane can overturn or break down.
Shearing, entrapment: the crane has a lot of parts in movement that it is
impossible to cover; therefore the operator shall always be aware of this resi-
dual risk and keep clear from the parts in movement, particularly from the
load; the operator is held responsible not only for himself but also for those
working in proximity of the crane and for those who may draw closer even if
not authorized.
Electricution: the crane is not insulated from electric contacts and therefore it
is not equipped to work under tension, even if the contact is accidental.
Therefore be compliant with the min clearance prescribed by the national
directives in force. Generally speaking the clearance from electric lines with a
max tension of 38.000 volts should be at least 5 meters: Higher tensions requi-
re higher clearance to be verified case by case together with competent tech-
nicians and with respect to the environment conditions.
Manual extension overload: manual extensions are controlled by the
moment limiting device only under the conditions described in the relative
chapter; the control system of the manual extension overload must be activa-
ted by the operator as described.
Accessories: be careful when assembling and disassembling the accessories
(extensions, buckets, baskets,…); first verify the weight, the securing systems
and the instructions for assembly and dismantlement; then appraise their bary-
centre and provide for adequate provisional blocking systems in order to avoid
sudden movements.
(!) ATTENTION (!)
If in the folding condition the hook is out of truck size, it must be taken
away before travelling.
Breakdown of some sensors
The system "moment limiting device - intelligent type" is always monitored
during ignition (the system, after having activated the various circuits, checks
the presence of all the inputs for around 4 seconds) and then continuously
monitors the operation and the efficiency of the limiting device (approx. every
25 milliseconds).
For most of the components the system checks also the congruence of the
incoming signal with the one the system expects.
Maintenance: maintenance is particularly important; the lack of it may dama-
ge things or hurt people.
Particular operations: if you are required to operate under particular conditions
not illustrated in the manual of use and maintenance, analyse carefully the situa-
tion and always refer to an authorised Fassi shop or to the Fassi technical support
service or to experienced operators before starting working.
