WIRE ROPE INSTALLATION
NOTE The wire rope manufacturer’s recommendations take
precedence over the following information.
Wire Rope Specifications
See the Wire Rope Specifications Chart in the Capacity
Chart Manual for the correct type, size, and amount of wire
rope to be installed on the crane.
The Wire Rope Specifications Chart contains the following
information:
• Parts of the line required for various loads.
• Wire rope lengths and notes about hoisting distance for
various parts of the line.
• Maximum spooling capacity of the load drums.
Wire Rope Storage
Store the wire rope in coils or on reels off the ground or floor
in a clean, dry, indoor location. If outdoor storage is
necessary, the wire rope must be covered with a protective
wrapper.
Keep the wire rope away from acids, fumes, and other
corrosives. Keep the wire rope away from heat that can dry
out the lubricant.
If the storage period will be long, lubricate the wire rope and
perform the periodic inspection given the Service Manual at
least monthly.
Seizing and Cutting Wire Rope
Apply tight seizings of annealed wire to the ends of all wire
rope. If not done, the rope wires and strands may slacken.
This will result in overloading of some strands and under-
loading of others. Bird-caging and breakage of the wire rope
can occur.
Before cutting the wire rope, apply seizings on both sides of
the point where the cut will be made. Then cut the wire rope
with a torch, rope cutter, or abrasive cut-off wheel.
See Figure 4-106
for:
• The number of seizings to be applied to the ends of the
wire rope and to both sides of the point where a cut will
be made.
• The proper application method. Each seizing should be
one rope diameter long.

Place the free end of the seizing wire in the valley between
two stands. Then wind the seizing wire over the free end as
shown. Finally, twist and pull the two ends of seizing wire
together until the seizing is tight.
Wind the seizing wire around the wire rope as shown. Then
twist the two ends of seizing wire together at the center of the

tight.
