With heap stacker) or special solutions such as a technical conditions prohibit conventional issues. Moreover, extended range and operability can be achieved leaching the ore is piled onto a site mobile stacking bridge or the lizard® impoundments (wet tailings).

How you benefit: • De-bottlenecking of operating time through mobile bridge systems • Maximum flexibility through integrating grasshoppers • Lower investment costs and fewer fatigue issues on bridge structures thanks to lizard® • Solutions for both stacking and reclaiming • Automation features like “float” multi crawler control mechanism Industrial Solutions thyssenkrupp Industrial Solutions AG thyssenkrupp Allee 1 45143 Essen, Germany [email protected] www.thyssenkrupp-industrial-solutions.com.
