600E2 OPERATOR MANUAL SAFETY PRECAUTIONS
Equipment operation is dangerous when close to an
energized electrical power source. Exercise extreme caution
and prudent judgment. Operate slowly and cautiously when
in the vicinity of power lines.
Before operating this equipment in the vicinity of electrical
power lines or equipment, notify the power utility company.
Obtain positive and absolute assurance that the power has
been turned off.
This equipment is not insulated. Always consider all parts of
the load and the equipment, including the wire rope, hoist
cable, pendant cables, and tag lines, as conductors. You, the
operator, are responsible for alerting all personnel of
dangers associated with electrical power lines and
equipment. Do not allow unnecessary personnel in the
vicinity of the equipment while operating. Permit no one to
lean against or touch the equipment. Permit no one,
including riggers and load handlers, to hold the load, load
lines, tag lines, or rigging gear.
If the load, wire rope, boom, or any portion of the equipment
contacts or comes too close to an electrical power source,
everyone in, on, and around the equipment can be seriously
injured or killed.
Most overhead power lines are not insulated. Treat all
overhead power lines as being energized unless you have
reliable information to the contrary from the utility company
or owner.
The rules in this Operator Manual must be followed at all
times, even if the electrical power lines or equipment have
been de-energized.
The safest way to avoid electrocution is to stay away from
electrical power lines and electrical power sources.
It is not always necessary to contact a power line or power
source to become electrocuted. Electricity, depending on
magnitude, can arc or jump to any part of the load, load line,
or equipment boom if it comes too close to an electrical
power source. Low voltages can also be dangerous.
Set-Up and Operation
During equipment use, assume that every line is energized
(“hot” or “live”) and take the necessary precautions.
Set up the equipment in a position such that the load, boom,
or any part of the equipment and its attachments cannot be
moved to within 6 m (20 ft) of electrical power lines or
equipment. This includes the equipment boom (fully
extended to maximum height, radius, and length) and all
attachments (jibs, rigging, loads, etc.). Overhead lines tend
to blow in the wind so allow for lines’ movement when
determining safe operating distance.
A suitable barricade should be erected to physically restrain
the equipment and all attachments (including the load) from
entering into an unsafe distance from electrical power lines
or equipment.
Plan ahead and always plan a safe route before traveling
under power lines. Rider poles should be erected on each
side of a crossing to assure sufficient clearance is
maintained.
