Be sure to use the correct rope lay direction for the drum. This applies
to smooth, as well as to grooved drums.
Many crane models have a two sided grooved drum, one part of it is left,
the other right lay grooved. Some wire ropes are more sensitive to this
type of design than others; it depends on lifting height, frequency of use,
and even the rope diameter as to the type of wire rope most suitable for
that application.
In some applications it may be advisable to select the rope lay direction
according to the most frequently used drum layers (if more than one layer
is spooled). If the first rope layer on a drum is used as a 'guide layer'
only, it may be advisable to select the rope lay direction according to
the second drum layer.
