7.5 Residual risks
Note: This reasoned list does not carry the complete list of the residual risks,
which are examined more in detail paragraph by paragraph in the manual
under "(!) ATTENTION (!)"; it is instead a way to exemplify to the operator the
types of hazards linked to the use of the crane, which basically involves a lifted
load in movement. Therefore we confirm you the following
It is absolutely forbidden to use the crane without having read and
understood the manual for use and maintenance and without having
being previously instructed by experienced personnel on all aspects of
safe crane operation.
Risk evaluation shall be followed by adequate provisions in order to
avoid risks and damages to people and things.
The crane operator shall be held directly responsible for the correct ope-
ration of the crane also according to the jobsite conditions.
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.
Moment limiting device: never try to bypass nor tamper with the moment
limiting device and the various safety systems installed on the crane. In such
case the operator shall be held responsible for the subsequent crane perfor-
mance. It is also important to understand the alarm messages generated by
the "moment limiting device" and act consequently.
Control seat: before operating from the control seat the operator shall make
sure that he's safe from hazards (i.e. he stands clear of the load, there is a
way of escape,..). Otherwise he shall manoeuvre from a different control seat;
if there is none available, the crane should be equipped with a radio control or
remote control in order to allow the operator to operate the crane in absolute
safety.
From the control seat the operator shall be able to visually inspect the whole
working area at all times. If it is not possible he shall team up with a co-worker
able to control the whole area; otherwise the crane shall be equipped with a
radio control in order to ensure the operator with the perfect position to see all
potential hazards clearly at all times. Naturally the operator shall also teach
this eventually co-worker with the scope of not harm each other with control
commands.
Load rigging: carefully inspect the load rigging; the operator shall make sure
that the load is properly attached and balanced and that all unexpected move-
ments are not allowed. Be careful not to hit any potential impediments during
the crane movements.
Jobsite conditions: prior to use always ascertain that the working area is free
and clear of potential obstacles to crane operations (people, building walls,
balconies, eaves, scaffoldings, tree branches, other lifting means or machi-
nes,electric lines,…). This may hurt people, damage both the impediments
and the crane, and provoke also the crane overturn.
Make sure that there is no risk of elements falling on the operator or on the
crane and take the right precautions to prevent it.
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
