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.

FAQ - Time lost due to lubrication failure in excavators
Posted by Chris Padman
on 23 July 2020
)
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 ...
