counterclockwise by hand, so the twisted portion of
the wires is near the middle of the seizing, as shown
in step 2. Grasp the ends with end-cutting nippers and
twist up the slack, as shown in step 3. Do not try to
tighten the seizing by twisting. Draw up on the seizing,
as shown in step 4. Again twist up the slack, using
nippers, as shown in step 5. Repeat steps 4 and 5 if
necessary. Cut the ends and pound them down on the
rope, as shown in step 6. When the seizing is to be
permanent or when the rope is 1 5/8 inches or more in
diameter, use a serving bar, or iron, to increase tension
on the seizing wire when putting on the turns.
Wire rope can be cut successfully by a number of
methods. One effective and simple method is to use a
hydraulic type of wire rope cutter, as shown in figure
5-27. Remember that all wire should be seized before
it is cut. For best results in using this method, place
the rope in the cutter, so the blade comes between the
release valve closed,
at the location of the
cut and continue to operate the cutter until the wire
rope is cut.
Wire rope should be inspected at regular internals,
the same as fiber line. The frequency of inspection is
determined by the use of the rope and the conditions
under which it is used.
Throughout an inspection, the rope should be
examined carefully for fishhooks, kinks, and worn and
corroded spots. Usual] y breaks in individual wires will
be concentrated in areas where the wire runs
continually over the sheaves or bend onto the drum.
Abrasion or reverse and sharp bends cause individual
wires to break and bend back These breaks are known
as fishhooks. When wires are slightly worn but have
broken off squarely and stick out all over the rope, that
condition is usually caused by overloading or rough
handling. If the breaks are confined to one or two
