Wire Rope Selection - Allied Systems W8L Operating Manual

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
Load loss hazard.
A wire rope that breaks under high tension
can suddenly whip back towards the
winch, causing injury or product damage.
Be sure the operator knows the capacity
of the wire rope and the winch.
WARNING
Load loss hazard.
A loaded wire rope with fewer than
three complete wraps on the drum
could disengage from the ferrule pocket,
causing load loss and possible injury.
Paint the last fi ve wraps of wire rope a
contrasting color to alert the operator that
end of the wire rope has been reached.
