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 if used.
Contact your Manitowoc dealer for ground bearing
information.
HANDLING COMPONENTS
The major components are equipped with lifting lugs. The
lifting lugs are identified by the following symbol in the
assembly and disassembly illustrations.
When lifting lugs are not provided, use nylon lifting slings to
lift the components. If wire rope or chain slings are used,
install protective covering (such as sections of rubber tire)
between the slings and the component being lifted.
It is the crane owner’s/user’s responsibility to ensure that all
lifting slings, hooks, and shackles are in safe working order
and capable of handling the load applied to them.
RETAINING CONNECTING PINS
Connecting pins are retained in various ways:
• Wire-lock pins
• Quick-release pins
• Cotter pins
• Hitch Pins
• Safety pins
• Keeper plates with cap screws and lock washers
Do not operate the crane until all connecting pins are
installed and properly retained.

wrapping it with foam or bubble wrap and securely attaching
it to the enclosure frame so the assembly cannot be
damaged during transport.
