WARNING
4.4 Wire rope selection
During the useful life of a winch, the wire rope replacement costs are often the
highest expenditure. It is very important to select a rope that corresponds to the
intended use of the winch itself.
The majority of accidents that happen during the use of a winch are also caused by
the wire rope and therefore the selection of the appropriate wire rope becomes an
important safety precaution.
The wire rope’s minimum breaking load must be
at least twice the load
capacity of
the winch itself unless national standards and requirements demand a different ratio
of rope capacity vs the winch’s load limits.
The wire rope will spool on to the winch drum. To lessen the probability of an ac-
cident and to minimize the premature wear of the rope, it is important to comply
with the rule that the rope does not bend or curve less than ten (10) times the rope
diameter.

To obtain the best rope economy, it is recommended that it has a steel core and is
cross-wound.
