CRANE DISASSEMBLY
Read all of the topics on page 4-1 through page 4-10 before
proceeding.
Preparing Crane
1. Position the crane in the disassembly area.

for blocked crawler requirements.
• Crawler Blocking Diagram in the Capacity Chart
Manual for blocking dimensions.
Lowering Boom
1. Swing the boom to either side of center and lower the
load blocks and/or the hook-and-weight balls to the
ground. Take every precaution to prevent damage to the
load lines.
2. Swing the boom in line with the crawlers and slowly
lower the boom.
a. If equipped with a luffing jib, refer to the Luffing Jib
Operator Manual for lowering instructions.
b. If equipped with a fixed jib, disengage the jib stops
before the jib point contacts the ground.
c. If equipped with an upper boom point, remove the
bottom connecting pins when the upper boom point
just contacts the ground.
d. Position a block under the boom top sheaves to
prevent them from digging into the ground.
3. If equipped with suspension pendants —
- intermediate (Figure 4-102 on page 4-134
)
- drop-down (Figure 4-77 on page 4-100
