SET-UP AND INSTALLATION

ASSIST CRANE REQUIREMENTS

An assist crane is required for handling and installing the
following components:
• Rotating bed jacks
• Drum 3 (whip line)
• Crane (upperworks) counterweight trays and boxes
• Catwalks and steps
• Fixed mast
• Boom inserts
The assist crane must be capable of lifting 60,000 lb (27 216
kg) to a height of 30 ft (9,1 m). This is the weight of the mast
butt and top in the shipping configuration.
See Crane Weights in Section 1 of this manual for weights of
components

ASSEMBLY AND DISASSEMBLY NOTES

T h e c r a n e , b o o m , a n d j i b m u s t b e a s s e m b l e d a n d
disassembled by experienced personnel trained in erection
and operation of construction cranes.
Read and become thoroughly familiar with the instructions in
the applicable capacity charts, in this section, and in the
rigging drawings at the rear of this section before attempting
to assemble, operate, or disassemble the crane.
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 jack pads and carbody pedestals on a flat, firm
foundation that will support the load placed on them. See
Table 4-1 for loadings.
Do not set the jack pads or carbody pedestals in holes, on
rocky ground, or on extremely soft ground.
If necessary, use wood blocking or steel plates under the
jack pads and carbody pedestals 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 Technical Services Department at factory for ground
bearing information.

ACCESSING PARTS

Some parts of the crane, boom, and jib cannot be reached
from the ground. Take necessary precautions to prevent
fa llin g o ff th e c ran e o r bo om during as se mbly a nd
disassembly. Falling from any elevation could result in
serious injury or death.
Owner/user shall provide approved ladders or personnel
hoists so workers can safely access those areas of crane,
boom, and jib that cannot be reached from ground. Adhere to
local, state, and federal regulations for handling personnel.
Do not use top of boom or jib as walkways.
Optional boom ladders are available from Manitowoc. If your
crane has ladders, see the instructions later in this section.

CRANE WEIGHTS

See Crane Weights in Section 1 for overall weight of the
crane and individual weights of components.

HANDLING COMPONENTS

The major components are equipped with lifting lugs which
are identified in the assembly and disassembly steps.
When lifting lugs are not provided, use nylon lifting slings. If
wire rope or chain slings are used, install protective covering
(such as sections of rubber tire) between slings and
component being lifted.
• Ensure straps for boom inserts and top remain pinned
and secured in the shipping position during handling
and transportation unloading
