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.

As with all businesses in this uncertain time, ZEMEK is implementing practices so that we can continue to operate while keeping our staff, clients and our suppliers safe. Here's how we are doing it: Working from home Zemek staff are working from home when possible, minimising contact between staff. Although the office always remains staffed as usual for any in person enquiries, of course while maintaing a safe social distance. Staff who remain in the office or workshop have plenty...

Examining the application of polymer bushings in mining equipment At ZEMEK, we don't just offer solutions we create them. To ensure we stay on the cutting edge of mining equipment and technology, we collaborate with world-class leaders and academics to design and develop mining equipment. We're currently collaborating with UQ Materials Performance (UQMP) a professional engineering consultancy and research business based at the University of Queensland in Brisbane. UQMP'...

ZEMEK and JAWS join forces for dipper door upgrades  ZEMEK has been involved with the Australian mining industry since the 1970's. During that time, we've evolved from a local business to an international solutions provider. We're incredibly proud of our success but it wouldn't be possible without collaboration. Over the years, we've been fortunate to work with some of the leading brands in mining. In 2017/18, we joined forces with JAWS Buckets & Attachm...
