5/2020 CC1908S-1 5-3
Wear rubber-soled shoes and rubber gloves,
and be careful that body parts unprotected
by rubber or other insulation do not come
into contact with the wire rope or machine
frame.
Deploy a marshaller to oversee that the
boom, wire rope, or machine frame does not
move too close to the electrical cable.
Contact the electricity company for
information on the voltage of the electrical
cables at the worksite.
Maintain the distance (safe distance) shown
in the following table between the
boom/machine frame and electrical cables:

PROCEDURES WHEN ELECTRIC SHOCK
ACCIDENTS OCCUR
If an electric shock accident occurs, stay calm
and act in accordance with the following
procedures:
1. Report
Immediately contact the electricity company
or related management company to have the
power turned off and for instructions on
emergency procedures.
2. Evacuation of related personnel from the
vicinity of the machine
Evacuate all personnel, including workers,
from the vicinity of the machine to prevent
secondary accidents.
Persons who have sustained electric shocks
by holding sling ropes, guide ropes, or other
conductors when the machine became live
should be instructed to evacuate on their
own.
Never attempt to help persons affected by
electric shock, as this may result in
secondary accidents.
3. Emergency procedures
Take the following action if persons have
sustained electric shock due to the machine
being live:
(1) If the machine can be operated,
immediately move it to a safe location
away from the electricity source. Take
care here, as transmission cables may
have been severed.
(2) Move the machine to a safe location,
confirm that it is no longer live, then
rescue any persons suffering from
electric shock and take them immediately
to a hospital.
4. Procedures after accidents
Do not use the machine again after
accidents. Otherwise, there is a risk of other
unforeseen accidents occurring.
Contact us or our sales service agency for
repairs.
PRECAUTIONS WHEN OPERATING CRANE
IN LOCATIONS WITH HIGH-POWER
MICROWAVE EMITTERS
Operating the crane near high-power microwave
emitting equipment such as a radar or TV/radio
broadcast antennae is extremely dangerous, as
induced currents may be generated in the crane
structure. Microwaves may also disrupt the
mechatronics.
When working in such locations, install a ground
connection between the machine and earth.
Slinging operators must also wear rubber boots
and rubber gloves to protect against electric
shock from parts such as the hook or wire.
