BEWARE OF ELECTRICAL CABLE ABOVE
• Do not let the machine touch the electrical cables above.
High voltage cables may also inflict electrical shock by close
proximity.
• Slinging operators are likely to suffer electrical shocks.
Always observe the following to prevent accidents.
• If the boom or the wire ropes may contact an electrical cable in
the workplace, consult the electricity company and make sure
that the measures (for instance placement of a guard personnel
or application of wrap tubes and warning tags to the electrical
cable) stipulated by the related regulations are taken before
starting work.
• Put on rubber soled shoes and rubber gloves, and be careful
that the body parts unprotected by rubber or other insulation do
not contact the wire rope or the machine frame.
• Place a guide and let them watch so that the boom, wire rope or
machine frame does not go near the electrical cable too much.
Before doing so, decide the emergency signs and other
necessities.
• Ask the electricity company for the voltage in the electrical
cables at the work site.
• Keep a safe distance shown in the following table between the
boom/machine frame and electrical cables.
MEASURES WHEN ELECTRIC CHARGE ACCIDENT OCCURS
If an electric charge accident occurs, react calmly and take measures in the following procedure.
1. Report
Immediately report to the electricity company or related management company, and receive
instructions for the power transmission stop, emergency procedures and related matters.
2. Evacuation of related personnel from vicinity of machine
Evacuate all personnel, including workers, from the vicinity of the machine to prevent secondary
disasters.
Personnel who suffered electrical shock by holding a sling rope, guide rope or other conductor when
the machine was charged should evacuate by their own effort.
Do not try to help personnel affected by electric shock. Otherwise, secondary electrical shock
accident will occur.
3. Emergency procedure
In the case of personnel receiving an electric shock due to the machine being electrically charged, do
the following:
(1) If the machine is operational, immediately move it to a safe location away from the cause of the
electrical charge. Take care not to break or disrupt the distribution power cable.
(2) Move the machine to a safe location, and after making sure the machine is not electrically
charged, take the affected personnel to the hospital.
4. Measure after accident
After the accident, do not reuse as is. Such attempt may cause unexpected accidents and enhances
failures.
Ask us or our sales service agency for repair.
