PICTOGRAMS USED TO INDICATE DANGERS
Warning danger from suspended loads being moved by the hoist.
MEANING
PICTOGRAM
Warning danger of crushing due to mechanical machine-parts in movement.
Warning danger of entanglement or dragging from machine-parts in motion
(wire ropes, drum, pulleys, wheels, etc.)
Signals the presence of live voltage and is fixed to electrical equipment
and on any structure which has live electrical voltage inside.
It is forbidden to transit, remain or manoeuvre under the suspended load.
Before putting the hoist into service it is necessary:
• To read the technical documentation carefully;
• To find out about the functioning and the positioning of the emergency stop device;
• To know which safety devices are installed on the hoist and where they are positioned;
Some activities to be carried out on functioning components (e.g. replacing a wire rope) expose the operators to
situations of danger, so staff must be authorised and properly trained regarding the operating procedures to follow,
the dangerous situations that could occur and the correct methods for preventing them.
3.2
General safety regulations
3.3
Safety symbols
In the manual pictograms are used to underline or bring attention to potentially dangerous situations due to residual
risks, or to actions which must be performed obligatorily according to the safety procedures shown in this manual.
It is forbidden to touch wire ropes and pulleys in motion.
It is forbidden to tamper the overload device and to modify its values.
It is forbidden to carry out manoeuvres during maintenance phases
of moving machine-parts
It is forbidden to remove the safety devices on a machine in motion.
It is compulsory to wear protection gloves.
Comply with the instuctuctions as stated within the manual.

Having carefully considered the possible dangers in all the operating phases of the DRH electric wire rope hoist and
related travelling trolleys, necessary measures have been taken to eliminate, as far as possible, risks to the operators
and/or limit or reduce the risks derived from dangers not totally eliminable at source. Nevertheless, despite all the
precautions taken, the following remaining risks which are eliminable or reducible with the relevant prevention
activities, still exist:
3.4
Warning about remaining risks
•
It is forbidden
to lift loads
while people are passing throu-
gh the related manoeuvre area.
•
It is forbidden
to transit,
remain or manoeuvre under
the suspended load.
•
Warning!
Exposure to the parts
in motion can create dangerous
situations.
•
It is forbidden
to touch wire
ropes and pulleys in motion.
• The operator must follow the
indications to obtain maximum
safety by observing the
indications in this manual.
• Obligation to do periodical
checks of the wire rope and the
hook.
• Obligation to use protective
gloves during the phases of
positioning of the hook block
for putting the load in the
sling.
risk from danger of crushing
during the manoeuvring of loads
suspended when the operator or
other staff are in relevant zones/
areas in the path of the load.
risk from dangers of
entanglement and/or crushing
after contact with wire ropes and
pulleys in motion.
RISKS DURING USE
DANGER/RISK
BAN/WARNING
OBLIGATION/PREVENTION
It is forbidden
to intervene on
electrical equipment before
having switched off the hoist
from the electric power line.
•
Warning!
Exposure to the
parts in motion can create
dangerous situations.
•
It is forbidden
to turn the
hoist on again if the removed
protection has not been put
back in place.
• Entrust electrical maintenance
operations to qualified staff.
• Carry out checks on electrical
equipment prescribed in the
manual.
• Entrust wire rope replacement
operations to qualified mainte-
nance staff.
• Obligation to use protective
gloves.
risk from danger of
electrocution-electric shock
during maintenance of electrical
equipment without having
disactivated the electric power
supply.
risk from entanglement/
crushing
in case of contact with the drum
in rotation in the wire rope
replacing phase.
