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. 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 ...

A -  Zemek have observed these steps can provide improvements to the life of components and ropes -  Correct alignment of system mechanism. Use of engineering polymer guide components limits wear to mating components. Low friction components reduce load and wear on ropes particularly. Revised trip sheave design shown to extend rope life.
