A NSW Coal Mine operating heavy excavators was suffering down-time due to failure of lubrication lines.  Wearite bushes were fitted to these machines, achieving 10,000hr life and reducing machine down-time.  Industry: Coal Mining                   Product: Wearite Blue Excavator Bushes Challenge A NSW Coal mine operated Hitachi EX3600 and EX5600 excavators as their principal digging equipment.  These machines had for yea...

  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.
