I. Core failure. This type of damage is usually
indicated by a reduction in the nominal diameter
or an increase in rope lay length. If these
conditions are noted, open up the wire rope and
inspect the core. Replace the rope if the core is
broken. See fig. 3 for a recommended method
of opening the core
Lubrication
Wire rope is lubricated during manufacture so that the strands -- as well as the
individual wires in the strands -- may move and adjust as the rope moves and bends.
But no wire rope can be lubricated sufficiently during manufacture to last its entire life.
As a result, it is important to lubricate periodically throughout the life of the rope.
The surface of some ropes may become covered with dirt, rock dust or other material
during their operation. This can prevent field-applied lubricants from properly
penetrating into the rope, so it's a good practice to clean these ropes before lubricating.
The lubricant applied should be light-bodied enough to penetrate to the rope's
core. There are three methods commonly used to apply a lubricant: drip it on rope,
