The solution helped the open gear achieve 40 years of service.
Application
P&H Rope shovel application in dusty conditions. Ring gear changes are normally done every 10 years.
Identify
By working collaboratively with the mine it was determined that high performance grease should be used from early in the machines operation life.
Agree
It was agreed to use Castrol Molub Alloy 936 NG to achieve benefits of:
- Maximum component life time
- Lowest lubricant related maintenance
- Lowest operating costs
- Maximum machine availability
Deliver
After 40 years:
The ring gear has not been replaced as a result of proper lubrication.
- Negligible signs of wear
- No time lost to replacement
Massive savings were achieved due to the non-replacement Cost avoided ZAR 5 M.
