7. Lubricant Penetration
To inspect internal lubricant penetration, use a sharp spike or heavy-duty
screwdriver to open the wire rope. Alternatively, two pipe wrenches secured one
metre apart, and rotated in opposite directions will allow visual inspection.
Lubricant penetration to the wire rope core is often difficult due to the following:
• Wire rope design, particularly anti-spin and locked core wire ropes.
• Dirty or contaminated wire ropes. (Using a Viper Wire Rope Cleaner is
recommended).
• Ropes contaminated with solid used lubricant coatings. (Using a Viper
Wire Rope Cleaner is recommended).
During the wire rope operation, the rope movement onto the drum and over
sheaves is known to assist with the lubricant penetration.
If an NLGI#2 grade grease is used it may be necessary to pre-heat the lubricant at
ambient temperatures below 5°C (41°F) to ensure adequate penetration. Check
with lubricant suppliers for method of pre-heating and individual lubricant
specifications. Be sure that the lubricant used will adequately protect your wire
rope from corrosion and wear.
