OVERLOAD AND/OR FATIGUE
The crane can break down due to fatigue or overload:
- If it is misused (with cycles, loads or pump oil flow not pertinent to the crane class)
- If it is used for improper tasks (side, oblique or reversal pull)
- If it is used in poor jobsites (corrosive environment, too high or too low
temperature, foundry,… [see conditions of use])
- If the load exceeds the rated capacity indicated on the relevant plates
Utilize the crane only for the provided aims by the Use and Maintenance manual.
It is prohibited
the crane utilization for differents aims to those indicated in the
Use and Maintenance manual.
WRONG MANOEUVRING
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.
The crane can fall break or overturn if the operator performs a wrong manoeu-
vre, due to the lack of familiarity with the operation procedures or due to inade-
quate psychophysical conditions.
WEATHER CONDITIONS
Too high or too low temperatures may damage the components of the oleody-
namic and electric circuits. 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.
In the chapter "7.3 During operation" are indicated the utilization limits for the
temperature, the wind loads and the annexed danger (electrocution, collisions,
etc.).
OVERTURN
The crane can overturn, thus hurting people and damaging things specially in
following conditions:
- if it is not correctly stabilized
- if the moment limiting device is disabled
- if the ground conditions at the jobsite are not stable enough with respect to
the dimensions of the outrigger base and/or of the additional base plate
- if you increase the design dynamic increasing the pump oil flow.
In the chapter "7.3 During operation" are indicated the utilization limits for the
ground consistency and the load capacity of the ground.
SHEARING, ENTRAPMENT
The crane has a lot of parts in movement that it is impossible to cover.
The operator shall always be aware of this residual risk and keep clear from the
parts in movement, particularly from the load. The operator is held responsible
for himself and also for those working people in proximity of the crane, and for
those who may draw closer even if not authorized.
