6.4 RESIDUAL RISKS
In the machine there are still the following residual risks:
1. Sudden break of the rope-conductor. The break of the rope causes sudden movements of the
machine and of the rope or 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

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 rope-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.
6. Inhalation of the endothermic engine exhausting gas. The machine discharge exhausting gas
of the endothermic engine combustion.
To reduce to min. the risks the operator has to:

respect the working positions indicated in the manual

respect the indications of attention and prohibition indicated in the present manual

if necessary, use safety devices for the respiratory tracts.
7. Control lever that can be locked in working position. For functional reasons and comfort in the
use the control lever does not foresees the return to zero when released; anyway the machine is
equipped with two security devices which prevent the creation of dangerous situations: electric
limiting device of the pull on the dynamometer, which stops the power station when the stated
value is reached, and load pre-setting device, which maintains the settled pull adjusting
automatically the speed of the work.
To reduce to the minimum the risks the operator must:

put the electric limiting device of the pull on a value just superior of the regulating valves of the
pull (see par. 4.5)

plan the desired pull as described in the manual (see par. 4.5).
