Special Operating Conditions and Aerial Lift
Never operate the aerial lift during an electrical
thunderstorm.
When operating near transmitter/communication towers
where an electrical charge can be induced into the aerial lift:
• The transmitter shall be de-energized OR,
• Tests shall be made to determine if an electrical charge
will be induced into the aerial lift.
• The aerial lift must be provided an electrical ground.
• 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.
Grounding the Aerial Lift
The aerial lift may become charged with a buildup of static
electricity. This may occur especially when using synthetic
material in the outrigger floats or cribbing such as plastic or
when the outrigger floats are packed with insulating material
(e.g. wooden planks).
The aerial lift may be grounded using electrically conducting
material for grounding to prevent buildup of static electricity.
1. Hammer a metal rod (3, Figure 3-3) [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).
4. Connect the free end of the cable with a clamp (1) to a
good electrically conductive location on the frame.
ENVIRONMENTAL PROTECTION
Dispose of waste properly! Improperly disposing of waste
can threaten the environment.
Potentially harmful waste used in National Crane aerial lift
includes — but is not limited to — oil, fuel, grease, coolant,
air conditioning refrigerant, filters, batteries, and cloths which
have come into contact with these environmentally harmful
substances.
Handle and dispose of waste according to local, state, and
federal environmental regulations.
When filling and draining aerial lift components, observe the
following:
• Do not pour waste fluids onto the ground, down any
drain, or into any source of water.
• Always drain waste fluids into leak proof containers that
are clearly marked with what they contain.
• Always fill or add fluids with a funnel or a filling pump.
• Immediately clean up any spills.
MAINTENANCE
The aerial lift must be inspected prior to use on each work
shift. The owner, user, and operator must ensure that routine
WARNING
Risk of accidents due to electric shock!
Ground the aerial lift 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
WARNING
Risk of accidents due to electric shock!
Ensure that the connections between the cable and the
clamp are electrically conductive.
Do not attach the clamp to parts that are screwed on, such
as valves, covers or similar parts.
