Prepare Boom
See Figure 4-57 for the following procedure.
1. Lower the boom to the ground. Block if necessary.
2. Remove the load line from the upper boom point, if
equipped.
3. Remove and store the upper boom point. See Boom
Rigging Guide (#44 HL and LR) on page 4-72.
4. For the long reach top only, install the jib stop strut (8,
View D).
NOTE: Gussets on the outside of the strut must be facing
toward the ground.
See Figure 4-56
for the remaining procedure.
5. For heavy lift top only, install the jib backstay links
between the boom sections (Location A or B). See the
Jib Assembly Drawing for the proper mounting location.
a. If necessary, separate the boom sections to provide
space for the links.
b. Lift a backstay link into position on either side of the
required insert. The lug at the bottom of the
connecting holes in the link must be facing toward
the outside of the boom (see View E1).
c. Lift the backstay link upward and engage the hole in
the link with the washer (2, View E1) on the
underside of the insert connector.
d. For Location A, install the retaining pin (3a, View
E1) through the holes on the butt side of the link to
prevent the link from falling off the insert.
For Location B, move the support cable assembly
(3b, View E2) from the stored position to the raising
position to prevent the link from falling off the insert.
If necessary, adjust the cable length so the bottom
connecting holes are aligned when the assist crane
is disconnected.
e. Repeat step 5
b through step 5d for the backstay link
on the other side of the boom.
f. Reconnect the boom inserts.
Replace the standard horizontal connecting pins
with the longer 275 mm (10-27/32 in) connecting pin
(4, View E) supplied with the backstay links.
Install Jib Butt
See Figure 4-56 for the following procedure.
NOTE: The jib strut is shipped in the stored position on the
jib butt (see View A).
1. Lift the jib butt into position at the end of the boom top.
2. Align the holes in the jib butt with the holes in the boom
top and install the connecting pins (see View B).
Install Jib Inserts
See Figure 4-56 for the following procedure.
NOTE: The jib sections have FACT™ connectors:
• The top connectors are joined by fixed vertical pins that
hook into holes in the adjacent section (see View C).
• The bottom connectors are joined by removable
horizontal pins (see View D).
1. Pin the desired length of jib inserts to the butt.
NOTE: The tapered end of the pins must point inward.
2. Block the inserts at the ground level as the assembly
progresses.
Install Jib Top
Pin the jib top to the last insert or butt, depending on the jib
length.
WARNING
Falling Load Hazard!
Prevent possible injury. The load line can be damaged
and the load can fall if the following step is not performed.
If the jib top is equipped with load sensor sheaves
(see View F), remove and store the rope guard.
