•
Proximity devices are advertised to detect the existence
of electricity and not its quantity or magnitude.
•
Some proximity devices may detect only alternating
current (AC) and not direct current (DC).
•
Some proximity devices detect radio frequency (RF)
energy and others do not.
•
Most proximity devices simply provide a signal (audible,
visual, or both) for the operator; this signal must not be
ignored.
•
Sometimes the sensing portion of the proximity devices
becomes confused by complex or differing arrays of
power lines and power sources.
Do not
depend on grounding. Grounding of a crane affords
little or no protection from electrical hazards. The
effectiveness of grounding is limited by the size of the
conductor (wire) used, the condition of the ground, the
magnitude of the voltage and current present, and numerous
other factors.
Electrical Contact
If the crane should come in contact with an energized power
source, you must:
1.
Stay in the crane cab.
Don’t panic
.
2.
Immediately warn personnel in the vicinity to stay away.
3.
Attempt to move the crane away from the contacted
power source using the crane’s controls which may have
remained functional.
4.
Stay in the crane until the power company has been
contacted and the power source has been de-energized.
No one
must attempt to come close to the crane or load
until the power has been turned off.
Only as a last resort should an operator attempt to leave the
crane upon contacting a power source. If it is absolutely
necessary to leave the operator’s station,
jump completely
clear of the crane. Do not step off.
Hop away with both feet
together.
Do not
walk or run.
Following any contact with an energized electrical source,
the Manitowoc distributor must be immediately advised of
the incident and consulted on necessary inspections and
repairs. Thoroughly inspect the hoist rope and all points of
contact on the crane. Should the dealer not be immediately
available, contact Manitowoc Crane Care. The crane must
not be returned to service until it is thoroughly inspected for
any evidence of damage and all damaged parts are repaired
or replaced as authorized by your Manitowoc distributor or
Manitowoc Crane Care.
Special Operating Conditions and
Equipment
Never operate the crane during an electrical thunderstorm.
When operating near transmitter/communication towers
where an electrical charge can be induced into the crane or
load:
•
The transmitter shall be deenergized OR,
•
Tests shall be made to determine if an electrical charge
will be induced into the crane or load.
•
The crane must be provided an electrical ground.
•
If taglines are used, they must be non-conductive.
•
Every precaution must be taken to dissipate induced
voltages. Consult a qualified RF (radio frequency)
Consultant. Also refer to local, state, and federal codes
and regulations.
When operating cranes equipped with electromagnets, you
must take additional precautions. Permit no one to touch the
magnet or load. Alert personnel by sounding a warning
signal when moving a load. Do not allow the cover of the
electromagnet power supply to be open during operation or
at any time the electrical system is activated. Shut down the
crane completely and open the magnet controls switch prior
to connecting or disconnecting magnet leads. Use only a
non-conductive device when positioning a load. Lower the
magnet to the stowing area and shut off power before
leaving the operator’s cab (if equipped) or operator’s station.
Earthing the Crane
The crane may become charged with static electricity. This
may occur especially when using outrigger pads made of
plastic or when the outrigger pads are packed with insulating
material (e.g. wooden planks).
Use electrically conducting material for earthing.
1.
Hammer a metal rod (3, Figure 2-6) (length of
approximately 2.0 m (6.6 ft)) at least 1.5 m (5 ft) into the
ground.
2.
Moisten the soil around the metal rod (3) for better
conductivity.
3.
Clamp an insulated cable (2) to the metal rod (3), cross-
section of at least 16 mm² (0.025 inches²).
WARNING
Risk of accidents due to electric shock!
Earth the crane before you start to work with it
•
Near strong transmitters (radio transmitters, radio
stations, etc.)
•
Near high-frequency switching stations
•
If a thunder storm is forecast
Reference Only
