ASSEMBLY AND DISASSEMBLY NOTES
The crane, boom, and jib must be assembled and
disassembled by experienced personnel trained in erection
and operation of construction cranes.
Before attempting to assemble, operate, or disassemble the
crane, the experienced personnel shall read and become
thoroughly familiar with the following:
• The instructions in the applicable capacity charts located
in the Capacity Chart Manual or at the end of this
section.
• The safety, assembly and disassembly instructions in
this section.
• The instructions in the Boom and Jib Assembly
Drawings located at the end of this section.
Contact your Manitowoc dealer for assistance if any
procedure is not fully understood.
ASSEMBLY AND DISASSEMBLY AREA
Select an assembly/disassembly area that has a firm, level,
uniformly supporting surface. Make sure the area is large
enough to accommodate the crane and the selected boom
length, movement of trucks with trailers, and movement of an
assist crane.
Set the carbody jack pads on a flat, firm foundation that will
support the load placed on them. See Table 4-1
for loadings.
Table 4-1
Do not set the carbody jack pads in holes, on rocky ground,
or on extremely soft ground.
If necessary, use wood blocking or steel plates under the
carbody jack pads to properly distribute loading. The wood
blocking or steel plates must be:
• Free of defects
• Strong enough to prevent being crushed or bent
• Of sufficient length and width to prevent settling under
load
Contact your Manitowoc dealer for ground bearing
information.

Some parts of the crane, boom, and jib cannot be reached
from the ground. Take the necessary precautions to prevent

Falling from any height could result in serious injury or
death.
