Wire Rope Lubrication
Wire rope used on IMT cranes does not have continuous lubrication replenishment. Use open
gear lubricant to protect the wire rope on your crane. The areas of rope which experience the
most wear are located over sheaves or are otherwise hidden, and these areas require the most
rope lubrication.
Lubricate the wire rope using ChainMate™ Chain and Wire Rope lubricant, Vitalife® 400, or
equivalent. To lubricate the rope:
1
Clean dirt, dust, and foreign matter from the rope.
2
Apply ChainMate lubricant or equivalent, penetrating the strands of the rope. Apply
according to the lubricant specifications.
3
Apply lubricant heavily to portions which encounter bending such as at the sheave and
winch.
Wire Rope Maintenance
If the daily wire rope inspection shows a problem with the wire rope, the rope must be repaired
or replaced. Use only original wire rope from IMT. Failure to do so may cause problems with
the anti-two-block system and the downhaul weights.
Wire Rope Inspection & Replacement
Wire rope with any of the deficiencies shown below shall be removed and replaced immediately.
a
Corrosion can be cause for replacement. Any development of corrosion must be noted and
monitored closely.
b
When there are either three broken wires in one strand or a total of six broken wires in all
strands in any one rope lay.
