Boom Removal
Boom removal is the reverse of installation.
1. Prepare crane and boom as follows:
a. Position crane in disassembly area.
b. If required per capacity chart, travel front crawler
rollers onto blocking (at boom end of crane).
See Crawler Blocking Diagram in Capacity Chart
Manual for blocking requirements.
2. Lower boom to ground as follows:
• If equipped with a fixed or luffing jib, see Jib
Rigging Guide for procedure.
• If equipped with an standard upper boom point,
remove it before upper point contacts ground.
Upper point cannot support weight of boom.
• If equipped with an extended upper boom point,
make sure ground is clear of obstruction so upper
point rollers can roll freely as boom is lowered.
3. Remove standard upper boom point before it contacts
ground (Figure 4-47
, View C). Upper point cannot
support weight of boom.
4. Continue to lower boom onto blocking until boom straps
are resting in brackets on boom inserts.
Push intermediate suspension pendants to inner
side of boom as boom is lowered.
5. Remove and store intermediate suspension pendants,
links and pins. Block under inserts before removing
lower connecting pins.
6. Store insert straps and links.
NOTE It is not necessary to remove the boom straps. The
straps can be left on the inserts for shipping.
a. Rotate links at front end of inserts rearward for
storage (Figure 4-45
or Figure 4-46 View B).
b. Install storage pins (2, Figure 4-45
or Figure 4-46
View B) to secure links and straps.
c. Store boom hoist equalizer links on the equalizer
rails (Figure 4-45
or Figure 4-46 View E).
7. Disconnect load lines from load block and weight ball
and spool load lines onto load drums.
8. Remove wind speed indicator from jib top to prevent
damage during shipping (see Wind Speed Assembly
drawing at end of this section).
a. Disconnect electrical cable at base of wind speed
mounting bracket.
b. Remove nuts, star washers, and bolts from base of
wind speed mounting bracket.
c. Store indicator assembly in a safe place on crane.

WARNING
Tipping Hazard!
Prevent crane from tipping. Block ends of crawlers, if
required per capacity chart, before raising or lowering
boom from or to ground.
WARNING
Crushing Injury Hazard!
Boom inserts can collapse when connecting pins are
removed. Block both ends of each boom insert before
removing connecting pins.
Do not stand on, inside, or under boom inserts during
disassembly. Always stand outside boom inserts when
removing connecting pins.
Never work under or inside boom inserts that are not
securely blocked.
CAUTION
Pendant Damage!
Use extreme care while lowering boom equipped with
intermediate suspension. Boom straps can land on and
crush intermediate suspension pendants.
