GENMA Maintenance · Lubrication System | Wire Rope: Don't Wait Until It Runs Dry

Wire ropes are critical parts of GENMA machines. Don't just focus on wear and broken wires — lack of lubrication is often the real reason they wear out early.

Why do wire ropes need lubrication?

Wire ropes are made of multiple strands twisted together, with many tiny gaps inside. Lubrication helps to:
•    Reduce friction between strands and wires
•    Prevent rust (especially in salty port environments)
•    Absorb shock loads

Quick tips for GENMA wire rope lubrication

Most GENMA machines use galvanized wire ropes, which come with initial lubrication inside. But over time, that lubricant dries out — so regular checks and top-ups are needed.
•    Interval: Check every 1,000 hours — more often in harsh conditions (high salt, dust, etc.).
•    How to tell: Look at the rope under load. Does it still feel oily? If it looks dry, it's time to lubricate. Contact your GENMA service engineer or use a recommended wire rope lubricant.

Four steps to get it right
1.  Clean first: Use a brush or compressed air to remove dirt and rust. Avoid steam or high-pressure water — you don't want to push debris inside.
2.  Use the right lubricant: Choose a penetrating wire rope oil. Regular grease is too thick to get inside.
3.  Apply properly: Let the rope run slowly under load, then brush or spray evenly so the oil seeps between the strands.
4.  Don't overdo it: Too much grease attracts dust and speeds up wear. Just enough is best.

Proper wire rope lubrication extends its life and keeps operations safe. A little time spent now saves big trouble later.
