Raise Jib Strut
See Figure 4-39.
1. If the 30° jib offset will be used, pin the 30° offset
pendants (10A, Views A and B) to the backstay
pendants (10) with the pendant pins (7) and cotter pins.
2. Slowly haul in the whip line (12, Views B and C) from
Drum 1 to raise the jib strut (4) until the jib pendants (5
and 8) are tight.
Guide the pendants clear of the jib sections as the strut
rises. Do not allow the pendants to catch on the jib
section connecting pins or to rub against the jib sections.
3. Pin the backstay pendants as follows:
• For the 10° offset, pin the backstay pendants (10,
View A) to the backstay lugs (17) on the boom top
with the pendant pins (7) and cotter pins.
• For the 30° offset, pin the 30° offset pendants (10A,
View A) to the backstay lugs (17) on the boom top
with the pendant pins (7) and cotter pins.
4. Slowly pay out the whip line (12, View C and G) until the
backstay pendants are supporting the jib strut (4) and
the whip line starts to go slack.
5. Disconnect the button socket (14, View C) on the whip
line (12) from the strut raising arm (13).
6. Remove the button socket from the whip line and place it
to the side for later use.
7. Rotate the strut raising arm (13, View F), by hand, to the
stored position against the jib strut (4).
8. Route the whip line through the strut raising arm (13,
View F) and over the sheave in the jib strut (4).
9. Install the rope guide pin (16, View F) to retain the strut
raising arm in the stored position.
10. Pay out the whip line to the end of the jib top.
Deploy Strut Stops
See Figure 4-39.
Perform the following steps 1
-3 at each strut stop (18), one
side at a time.
1. Remove the pins (19, View D) from the end of the inner
stop tube (18A).
2. Support the inner stop tube and remove the stop pin (20,
View C).
3. Extend the inner stop tube (18A, View E) and pin it to the
strut stop lug (21) on the boom top.
4. Install the stop pins (20, View F) in the desired offset
holes (A or B).
Boom up (extend strut stops) if necessary to provide
adequate clearance for installing the stop pins in the
desired holes.
