Remove Boom
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 a standard upper boom point,
remove it (reverse assembly steps) before upper
point contacts ground. Upper point cannot support
weight of boom
• If equipped with an extended upper boom point,
make sure foundation is clear of obstructions so
upper point rollers can roll freely as boom is lowered
3. Continue to lower boom onto blocking until boom straps
are resting in brackets on boom inserts and equalizer is
resting on and pinned to boom rails (Figure 4-19
, View
E).
Push intermediate suspension pendants to inner
side of boom as boom is lowered.
NOTE If the boom will be used as the holdback to lower
the fixed mast do not disassemble the boom until
after the mast is lowered to 65°. See procedure for
lowering the fixed mast.
4. Remove and store intermediate suspension pendants,
links and pins. Block under inserts before removing
lower connecting pins.
5. Store insert straps and links (Figure 4-20
).
NOTE It is not necessary to remove the boom straps. The
straps can be left on the inserts for shipping.
6. Lift boom hoist equalizer off equalizer rails and move it to
the side so it is clear of boom disassembly area.
Take every precaution to protect wire rope from
damage.
Do not allow wire rope to jump off sheaves (in mast
and equalizer) or otherwise become fouled.
7. Disconnect electric cables between boom and jib points
and connect to proper receptacles on boom and jib
nodes. Clean all connectors and install protective
caps.
8. Remove and store wind speed indicator assemblies so
they cannot be damaged during shipping.
9. Disconnect load lines from load block and weight ball
and spool load lines onto load drums.
10. Remove fixed jib or luffing jib if installed.
11. Remove extended upper boom point if installed (reverse
assembly steps).
12. Store boom top wire rope guide (Figure 4-19
, View B):
a. Attach a sling from assist crane to hole in wire rope
guide (5).
b. Support wire rope guide (5) with assist crane.
c. Unpin struts (8) from wire rope guide and pin to
storage lugs (9).
WARNING
Tipping Hazard!
Prevent crane from tipping. Block ends of crawlers, if
required per capacity chart, before lowering boom to
foundation.
WARNING
Crushing Injury Hazard!
Boom inserts can collapse when connecting pins are
removed. Block both ends of each boom insert before
removing connecting pins.
Never work under or inside boom inserts that are not
securely blocked.
Do not use top of boom as a walkway.
CAUTION
Pendant Damage!
Use extreme care while lowering boom equipped with
intermediate suspension. Boom straps can land on and
crush intermediate suspension pendants.
WARNING
Crushing Injury Hazard!
Do not attempt to unpin straps until they are resting firmly
in strap brackets and equalizer is pinned to equalizer rails.
