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 him/her 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 worksite.
• Ensure the separation (safe distance) shown in the
following table between the boom/Machine frame and
electrical cables.
