DISTRIBUTING WIRE ROPE WEAR
Wire rope wear at the “critical wear points” can be reduced
and the life of the wire rope extended by moving the rope at
regular intervals so different sections of rope are subjected to
the wear points. This practice can also help correct spooling
problems and rope vibration.
To move the wire rope, cut off a piece of wire rope at the
drum and refasten it. The piece cut off should be long
enough to move wire rope at least one full drum wrap.
If the wire rope is too short to allow cutting off a piece of it,
reverse the rope end for end and refasten it.
