7.3 PERIODIC OPERATIONS
Daily, before starting the work, the operator has to verify the functionality of the machine safety devices.
ATTENTION: do not modify for any reason safety devices of the machine because
the manufacturer declines any responsibility as consequence of the non-
functioning of the same.
7.4 RESIDUAL RISKS
In the machine there are still the following residual risks:
1. Sudden break of the rope. 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
⇒
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 rope 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-conductor’s 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. Lockable control lever in working position . For functional reasons and convenience of use the control
lever does not provide for the return to zero in the case of returning; The computer of the remote control
is equipped with a setting screen control in case of an emergency situation. (see par.5.4.3.2) that allows
you to assign some screen buttons, the functions usually assigned to the control lever).
