5. Boom cages and boom guards afford limited protection
from electrocution hazards. They are designed to cover
only the boom nose and a small portion of the boom.
Performance of boom cages and boom guards is limited
by their physical size, insulating characteristics, and
operating environment (dust, dirt, moisture, etc.). The
insulating characteristics of these devices can be
compromised if not kept clean, free of contamination,
and undamaged.
6. Proximity sensing and warning devices are available in
different types. Some use boom point (localized)
sensors and others use full boom length sensors. No
warning may be given for components, cables, loads,
and other attachments located outside of the sensing
area. Reliance is placed upon the operator in selecting
and properly setting the sensitivity of these devices.
7. Never rely solely on a device to protect you and your
fellow workers from danger.
Some variables you shall know and understand are:
• Proximity devices are advertised to detect the
existence of electricity and not its distance, 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 and 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.
8. 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
(wire) conductor used, the condition of the ground, the
magnitude of the voltage and current present, and
numerous other factors.
Electrical Contact
If the crane comes in contact with an energized power
source, the operator shall:
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 are likely
to remain functional.
4. Stay in the crane until the power company has been
contacted and the power source has been de-energized.
NO ONE shall 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 cab, JUMP
COMPLETELY CLEAR OF CRANE. DO NOT STEP
OFF. Hop away with both feet together. DO NOT walk or
run.
5. Following any contact with an energized electrical
source, your Manitowoc Dealer must be immediately
advised of the incident and consulted on necessary
inspections and repairs.
If the dealer is not immediately available, contact the
Manitowoc Crane Care Lattice Team. 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 Manitowoc or your
Manitowoc Dealer.
REFUELING
1. When using a portable container to refuel the crane, the
container must be a safety-type can equipped with an
automatic closing cap and a flame arrester.
2. The engine must be stopped before refueling crane.
3. Smoking and open flames must be prohibited in
refueling area.
FIRE EXTINGUISHERS
1. A portable fire extinguisher with a minimum rating of 10
BC must be installed in operator’s or machinery cab of
crane.
2. The operator and all maintenance personnel shall be
thoroughly familiar with the location, use, and care of the
fire extinguisher(s) provided.
