Important!
• Use a sheave or roller guide to
direct the wire rope to the drum
whenever possible.
• Install sheaves, tracks and other
equipment so they will remain
fi xed under all load conditions.
Follow the recommendations of
the equipment manufacturer.
• Use sheaves of proper diameter
to minimize wear on the wire
rope. Follow the recommenda-
tions of the sheave manufacturer.
