NBT40 SERVICE MANUAL LUBRICATION
• of a viscosity capable of penetrating the interstices
between wires and strands.
• not be soluble in the medium surrounding it under the
actual operating conditions (i.e. Water).
• have a high film strength.
• resistant to oxidation.
Before applying lubrication, accumulations of dirt or other
abrasive material should be removed from the rope. Clean
with a stiff wire brush and solvent, compressed air, or live
steam. Lubricate the rope immediately after the rope is
cleaned. Techniques that can be used include:
• bath
• dripping
• pouring
• swabbing
• painting
• pressure spray
Whenever possible, the lubricant should be applied at the
top of a bend in the rope, because at that point the strands
are spread by bending and are more easily penetrated.
There should be no load on the rope while it is being
lubricated. The service life of wire rope is directly
proportional to the effectiveness of the method used and
amount of lubricant that reaches the working parts of the
rope.
