Case Study - Rope Shovel Trip Mechanism
P&H 4100XPC Queensland Coal  A Queensland Coal Mine operates electric rope shovels, these machines suffered frequent production losses to dipper trip mechanism failure.  This had the effect of shutting down the shovels themselves and standing down of the haul truck fleets.  Revised and optimised system components, along with improved alignment overcame the problem.  Challenge
A Queensland Coal mine operated Komatsu P&H 4100XPB/C rope shovels in overburden cle...

FAQ - Time lost due to lubrication failure in excavators

Posted by Chris Padman on 23 July 2020
FAQ - Time lost due to lubrication failure in excavators
  A. Polymer bushes such as Wearite can replace lubricated steel bushes in many parts of the excavator mechanism.  These materials are rated to the duty of heavy mining applications and can operate without lubrication.  Wearite users have been able to reduce the number of vulnerable lubrication lines and thus reduce downtime associated with failures in these lines.  Experience in excavators in the 300 tonne + class has shown a trouble-free life over.  Savings are ...

FAQ - How does magnetic filtration effect oil analysis and failure prediction?

Posted by Chris Padman on 10 July 2020
FAQ - How does magnetic filtration effect oil analysis and failure prediction?

 

 

A - Rare earth magnetic filtration systems remove most, but not all iron contamination from hydraulic systems; typically 60-70%.  The effect on oil analysis is that any trends in iron remain intact, just at a lower base-line.
