Identifying Inserts
See Figure 4-41 for the identification of the heavy, standard,
and light inserts.
Depending on the length and type of boom, boom sections
must be installed in the following sequence.
1. Boom butt
2. Any 3,0 m (10 ft) insert
3. Any 6,1 m (20 ft) inserts
4. Any 12,2 m (40 ft) heavy inserts (#44A)
5. Any 12,2 m (40 ft) standard inserts
6. Any 12,2 m (40 ft) light inserts
7. 12,2 m (40 ft) Transition insert (long reach boom only)
8. Boom top
Removable Lacings
See Figure 4-42 for the following procedure.
The 6,1 m (20 ft) and standard 12,2 m (40 ft) inserts are
equipped with removable diagonal lacings. This design
feature allows the lacings to be removed so that the jib
sections (fixed or luffing) can be stored inside the boom
inserts during shipment.
User-supplied blocking can be placed across the bottom
chords for supporting the jib sections during shipment.
NOTE: It is the user’s responsibility to securely fasten
blocking and jib sections so the sections cannot
move during shipment.
Prior to operating the crane after removing the jib sections
and all the blocking, the removable diagonal lacings must be
reinstalled.
1. Thoroughly clean all dirt from the mating surfaces
between the lacings and supports on the inserts.
2. Reinstall the proper number of removable lacings in
each insert with bolts and stop nuts.
3. Securely tighten the nuts.
WARNING
Tipping Crane Hazard!
Collapsing Boom Hazard!
The crane can tip or structural failure can occur if the
inserts are not installed in the proper sequence.
Boom and jib sections must be assembled in the proper
sequence according to Figure 4-47
, 4-48, or 4-49 and the
Boom and Jib Rigging drawings.
