General
Wire Rope Selection
Each winch model can have a variety of wire rope sizes
installed by the user. The maximum wire rope size is shown
on the nameplate. See Figure 2 for approved wire rope
sizes and drum capacities. When a larger diameter wire
rope is used, the length of wire rope installed on the drum
will be shorter. In some situations, the winch can create a
tension in the wire rope that is greater than the strength
of the wire rope. The user must be careful to select a wire
rope that has enough strength and length for the job.
WARNING
During operation of the winch, the
operator must know or estimate the line
pull and make sure that the line pull is
within the capacity of the winch and the
specifi cations of the wire rope installed
on the drum. A broken wire rope under
high tension can return suddenly in the
direction of the winch and cause injury
and damage.
For maximum wire rope strength, there should be at least
three wraps of wire rope on the drum. Painting the last ten
feet red will alert the operator that the wire rope is coming
to the end of its length.
