7.5 Residual risks
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.
(!) ATTENTION (!)
It is prohibited
the crane utilization not by qualified staff.
The operator is responsible for the machinery, its movements, the load
movement and all the working area of the crane.
Therefore it's necessary the maximun attention in all the phases of the crane ope-
ning and closing, of stabilization and of the load handling, it exist a series of resi-
dual risks, not predictable completely, which can create danger for the employed
in the crane handling
In the below list are indicated some residual risks, that have as danger a relie-
ved and in movement load, which request particular attention during the working
period.
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 performance. 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 is
safe from hazards (i.e. stand clear of the load, make sure that 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, must 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. The operator shall also teach this even-
tually 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 movements are
not allowed. Be careful not to hit any potential impediments during the crane
movements.
If the load sticks out of the maximum volumes of the vehicle, the operator must
make sure of the new maximum dimensions of volume, to avoid collisions with
the tunnels, the subways, the bridges and the electric lines.
JOBSITE CONDITIONS
Enclose the working zone. Prior to use, make sure 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 machines,
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.
