NOTICE
The serial number of the crane and applicable attachments (for example, a luffing jib or MAX-ER®) is
the only method a Manitowoc dealer or the Manitowoc Crane Care Lattice Team has of providing the
correct parts and service information.
The serial number is located on a crane identification plate attached to the operator cab and each
attachment. Refer to the Nameplate and Decal Assembly Drawing in Section 2 of this manual for the
exact location of the crane identification plate.
Always furnish serial number of crane and its attachments when ordering parts or discussing
service problems with a Manitowoc dealer or the Manitowoc Crane Care Lattice Team.
To prevent death or serious injury:
•Avoid unsafe operation and maintenance.
•Crane and attachments must be operated and maintained by trained and
experienced personnel. Manitowoc is not responsible for qualifying these
personnel.
•Do not operate or work on crane or attachments without first reading and
understanding instructions contained in the manuals supplied with crane
and applicable attachments.
•Store crane manuals in the operator cab.
•If crane manuals are missing from the cab, contact a Manitowoc dealer for
new ones.

equivalent value in desired units. For example, 3,6576 m is
converted to feet as follows:
3,6576 m ÷ 0.3048 = 12
