the boom sections.
The jib sections do not have lifting lugs.

lacings and chords.
• Use synthetic lifting slings (crane owner furnished) to
handle the jib sections. Lift at the chords only. Never lift
at the lacings.
If wire rope or chain slings are used to handle the boom or jib
sections, install protective covering (such as sections of
rubber tire) between the slings and component being lifted.

The lifting lugs on each boom section are designed only
for lifting that section. Do not attempt to lift two or more
boom sections with the lifting lugs on one section. The
lifting lugs may break allowing the boom sections to fall.
