sure that the weight of the load does not exceed the
crane’s rating at the radius where the load is handled.
The weight of the load must be provided to the operator
before the lift is made.
2. Boom Angle or Radius Indicator
Temporary alternative measures if inoperative or
malfunctioning:
a. Refer to the pendulum boom angle indicator on the
boom butt (viewable from operator’s cab).
b. Measure the boom angle with a protractor-level on
the centerline of boom.
c. Measure radius using a tape measure.
3. Jib Angle or Radius Indicator
Temporary alternative measures if inoperative or
malfunctioning. Use either or both:
a. First, make sure you know the boom angle (see item
2
above).
b. Then, measure radius using a tape measure.
4. Drum Rotation Indicator
Temporary alternative measures if inoperative or
malfunctioning:
Mark the drum to indicate its rotation.
If the operator cannot see the drum, add mirrors or
remote video cameras and displays so the operator can
see the mark.
5. OPTIONAL Swing Limiter or Proximity Device
Temporary alternative measures if inoperative or
malfunctioning:
The qualified person directing the lift shall establish
procedures to furnish equivalent protection (for
example, assign an additional signal person to observe
the distance between the boom or load and job site
obstructions to include power lines or to limit the swing
sector specified in the Capacity Chart).
6. OPTIONAL Drum Spooling Limiter
(maximum or minimum bail limit)
Temporary alternative measures if inoperative or
malfunctioning:
The qualified person directing the lift, the operator, or a
designated signal person shall watch the drum and
signal the operator to stop it before it is over spooled
(rope does not jump off drum) or before there are less
than 3 full wraps of wire rope on the load drum or boom
hoist.
7. OPTIONAL Closed-Circuit Television (CCTV)
Temporary alternative measures if inoperative or
malfunctioning:
A designated signal person shall watch the load, the
drums, and the counterweight and provide necessary
hand or voice signals to the crane operator.
ASSEMBLING, DISASSEMBLING, OR
OPERATING CRANE NEAR ELECTRIC
POWER AND TRANSMISSION LINES
Electrocution Hazard
Thoroughly read, understand, and abide by all applicable
federal, state, and local regulations regarding operation of
cranes near electric power lines or equipment.
United States federal law prohibits the use of
cranes closer than 20 ft (6 m) to power sources up
to 350 kV and greater distances for higher
voltages unless the line’s voltage is known
[29CFR1910.180 and 29CFR1926.1400].
To avoid death or serious injury, Manitowoc
recommends that all parts of crane, boom, and
load be kept at least 20 ft (6 m) away from all
electrical power lines and equipment less than
350 kV.
NOTE: For detailed guidelines on operating near power
lines, refer to the current edition of OSHA
29CFR1926.1400 and ASME B30.5 American
National Standard.
1. Keep all personnel and their personal belongings
(clothing, water coolers, lunch boxes, etc.) away from
the crane if it is being operated near electrical power
lines or equipment.
2. Before operating the crane 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.
The crane is NOT INSULATED. Always consider all
parts of the load and the crane as conductors, including
the wire rope, pendants or straps, and taglines.
WARNING
Electrocution Hazard!
Manitowoc cranes are not equipped with all features
required to operate within OSHA 29CFR1926.1408, Table
A clearances when the power lines are energized.
