SUPERSTRUCTURE TMS9000-2 SERVICE MANUAL
• In standing ropes, more than two broken wires in one lay
in sections beyond end connections or more than one
broken wire at an end connection.
• In rotation resistant rope, two randomly distributed
broken wires in six rope diameters or four randomly
distributed broken wires in 30 rope diameters.
• Severe corrosion as evidenced by pitting.
• Manitowoc recommends that for cable extended booms,
a single damaged wire rope assembly shall require
replacement of the entire set of extension cables.
• Manitowoc recommends for cable extended booms, that
boom extension cables be replaced every seven (7)
years.
The following tables show the number of wire breaks in a
length 6 times and 30 times the rope diameter which would
require rope replacement, for the most common rope
diameters.
NOTE: The number of visible wire breaks indicated here
only applies to the hoist ropes! This information
only applies to the initial equipment and original
spare parts!

Remember that other factors may also make it necessary
to replace the hoist rope before the number of wire breaks
requiring rope replacement has been reached (age of
rope, frequency of use or exceptional loading).
