MLC165-1 OPERATOR MANUAL SETUP AND INSTALLATION
SHIPPING CRANE COMPONENTS
It is the owner/user’s responsibility to ensure the following:
• All trailer loads comply with local, state, and federal
transportation requirements.
• All crane components are properly blocked and secured
so they cannot shift or fall off the trailers.
To avoid damage to components:
• Use synthetic tie-downs to secure components as
shown in Figure 4-44
, View A.
• If chain tie-downs are used, install protective covering
(such as sections of rubber tire) between the chain and
the component being secured as shown in Figure 4-44
,
View B.
• When securing boom sections, wrap the tie-downs over
the chords — never over the lacings. Keep the tie-downs
as close to the blocking as possible (View A) to prevent
bending the chords.
CRANE DISASSEMBLY
Before proceeding, read and understand all of the topics on
page 4-1
through page 4-6.
Prepare Crane
1. Position the crane in the desired disassembly area.
2. If required, block under the boom end of the
crawlers. See the following:
• Appropriate Liftcrane Boom or Jib Capacity Chart
for blocked crawler requirements
• Crawler Blocking Diagram in the Capacity Chart
Manual for blocking dimensions
Lower 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. See Lower
Boom and Jib on page 4-116.
c. If equipped with an upper boom point, remove the
bottom connecting pins when the upper boom point
just contacts the ground. See Figure 4-73 on
page 4-100.
3. Continue to lower the boom until the boom is resting on
blocking at least 9 in (229 mm) high placed under the
bottom connectors between the last insert and the boom
top.

Tipping Hazard!
Do not attempt to lower the boom or the boom and jib to
the ground until the crawlers are blocked, if required.
Otherwise, the crane will tip.
