ORDERING BOOM AND JIB LACINGS
B. Ordering Lacings without Lacing
Drawings
The parts order must contain the following information to
ensure that Manitowoc provides you with the correct lacings:
1.
Crane serial number (can be found on builders plate in
operator's cab.)
2.
Boom or jib identification number.
3.
Quantity, lacing location, and lacing number.
4.
Boom or jib component name (butt, insert, or top) and
part number.
NOTE:
To obtain the lacing location and number, view the
boom or the jib from the butt end looking forward.
Identify the side on which the damaged lacing is
located: left side, top side, right side, or bottom
side. Count each lacing up to and including the
damaged lacing, starting with
first lacing nearest
butt end
of the component as shown in Figur e3.
Do not count a diagonal lacing as the first lacing.
Identify diagonal lacing separately; lower end
diagonal lacing or upper end diagonal lacing.
ASSISTANCE
If you are in doubt as to which lacings to order, DO NOT
GUESS. Contact your nearest Manitowoc distributor for
assistance; doing so may prevent the wrong parts from being
shipped.
WELDING INSTRUCTIONS
Each lacing order is shipped with welding instructions and a
copy of Form 00SPFM006 which identifies the chord and
lacing material.
