DISASSEMBLE BOOM
Lower Boom onto Blocking
To prevent the crane from tipping, some boom lengths must
be raised and lowered over the end of blocked crawlers. See
Capacity Charts for blocked crawler requirements and
Crawler Blocking Diagram in Capacity Charts Manual for
instructions.
Do not attempt to lower the boom to the ground until the
crawlers are blocked, if required.
NOTE: The boom must be lowered onto blocking that is a
minimum of 6 in (152 mm) high at the butt end of
the transition insert.
The extended upper boom point may not fold
properly when lowered onto soft ground. For
that reason, prepare the lowering area with
steel plates or mating.
1. Swing to either side of center and lower the load block
and/or hook-and-weight ball to the ground.
2. Swing the boom back in line with the landing area and
lower the boom to the ground. Haul in the load lines as
the boom lowers.
3. The extended upper boom point rollers will roll forward
once they contact the ground.
Make sure roller path is clear of obstructions.
4. If equipped with intermediate suspension, proceed as
follows:
See Figure 4-22 for following steps.
a. As the boom nears the blocking, check to see if pins
(5, View B) are loose.
NOTE: The pins may loosen before the boom lands on the
blocking.
b. Once the pins are loose, remove them and open
latches (4, View A).
c. Continue to lower the boom until it is on the blocking
and bottom strut (1b, View D) is resting on supports
(2a, View F) or blocking (2b).
d. Close latches (4) and install pins (5, View B) for
storage.
e. Boom up or down as needed to loosen pins (3, View
C)
f. Remove pins (3).
g. Slowly boom down to fully lower top strut (1a) to
Position A (View G).
h. Install pins (3) to connect the top strut to the bottom
strut.
i. Slowly boom up to raise the intermediate
suspension strut approximately 12 in (305 mm).
j. Remove and store supports (2a, View F) or blocking
(2b).
5. Boom down until the all of the boom straps are resting in
the supports on the boom sections and straps and links
at the end of the boom butt are folded as shown in
Figure 4-21, View A.
Disconnect/Store Boom Wiring and
Components
1. Disconnect boom wiring:
See Figure 4-21 for following steps.
a. Disconnect electric cable (3, View C) (from boom)
from electric cable (2) on the crane.
b. Remove the sealing cap and connect terminator
plug (1, View C) to electric cable (2).
c. Connect the sealing cap to electric cable (3) and
store electric cable (3) on the boom butt.
d. Disconnect electric cables (4, View B) and (5
optional) from the node on front of the rotating bed.
e. Connect sealing caps to electric cables (4 and 5)
and store the cables in the boom butt.
See Figure 4-23 for remaining steps.
2. Disconnect the electric cables from the load cell, the
block-up limit switches, the wind speed transmitter, the
aircraft warning light from the boom node controller.
3. To protect electrical components:
a. Attach protective caps to the ends of all unused
cables, unused receptacles, and unused terminator
plugs.
WARNING
