• 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.
Seizing Wire Rope
It is important to seize the ends of rotation resistant wire
ropes to prevent the displacement and unraveling of the
individual wires and strands at the ends. All preformed and
non-preformed styles of wire rope should be seized prior to
cutting. Seizings must be placed on both sides of the point
where the wire rope is to be cut.
The two preferred methods for seizing wire ropes are:
Method 1
Using a length of soft annealed wire (Figure 1-10), place one
end in the groove between two strands of the wire rope. Turn
the long end of the annealed wire at right angles to the wire
and wrap it tightly over the portion in the groove.
The two ends of the annealed wire should be twisted
together tightly. Cut off the excess wire and pound the twist
flat against the wire rope.
Method 2
Wind a length of soft annealed wire (Figure 1-11) around the
wire rope at least seven times. The two ends should be
twisted together in the center of the seizing. Tighten the
seizing by alternately prying and twisting. Cut off both ends
of the wire and pound the twist flat against the rope.
NOTE: Non-preformed wire rope (1) (Figure 1-12) should
have three seizings (3) located on each side of the
cut (4) as compared to preformed wire rope (2).
