6.4 RESIDUAL RISKS
In the machine there are still the following residual risks:
1. Sudden break of the conductor. The break of the conductor causes sudden movements of the
machine and of the conductor connected to the machine.
To reduce to min. the risks the operator has to:

check the rope and replace it as soon as appear some defects or wear signs

respect the working positions indicated in the manual.
2. Sudden break of the anchoring stakes. The sudden break of the anchoring stakes causes the
machine instability and sudden movements of the same.
To reduce to min. the risks the operator has to:

periodically check the anchoring stakes and replace them as soon as appear some defects or
wear signs

follow the anchoring indications described in the present manual

respect the working positions indicated in the manual.
3. Entangling or dragging of the accessible rotating units. It is not technologically possible to
foreseen covering in correspondence of some rotating units (i.e. winding of the rope or of the
conductor on the bull-wheels or on the driving gears), due to an excessive restriction of the
machine functionality and operative functions.
To reduce to min. the risks the operator has to:

avoid any possible contact with the machine rotating units except for the control devices

follow the anchoring indications described in the present manual

respect the prescriptions indicated in the present manual concerning wearing and the necessary
safety devices.
4. Limbs crushing during loading or removal of the reel and during conductor loading.
These
operations have a large risk margin due to the use of mechanical parts to be moved.
To reduce to min. the risks the operator has to:

know the directives for accident prevention and apply them.
5. Electrostatic discharges.
The machine has not a proper grounding device for this reason during
stringing operation it is possible to have dangerous electrostatics discharges on ropes and
conductors.
To reduce to min. the risks the operator has to:

know the directives for accident prevention and apply them

check if the job site has a suitable grounding device for the machine-rope-conductors system.
