Handling Components
Handle boom and jib sections with care to avoid damaging
lacings and chords. All boom sections have lifting lugs as
shown in Figure 4-33
.
When lifting lugs are not used (as in the case of jibs):
• Lift against chords only, never against lacings
• Use nylon lifting slings. If wire rope or chain slings are
used, install protective covering (such as sections of
rubber tire) between slings and chords
Boom handling with mast pendants pinned to lifting
lugs on boom butt must be limited to boom length given
in Boom Assembly Drawing.
Assembly Drawings
Boom and jib components (top, inserts, butt, straps) must be
assembled in proper sequence according to applicable
Boom and Jib Assembly Drawings at end of this section.
WARNING
Falling Load Hazard!
Lifting lugs on each insert are designed only for lifting that
insert. Do not attempt to lift two or more inserts with lifting
lugs on one insert. Lifting lugs may break allowing inserts
to fall.
WARNING
Falling Boom Hazard!
Do not attempt to handle more boom with mast than
specified on Boom Assembly Drawing. Structural failure
of components can occur, possibly allowing boom to fall.
