MATERIAL HANDLING 62 E&MJ • JUNE 2019 Another important element of the lizard is its multi-crawler drive sys- tem. thyssenkrupp said it has applied a unique solution to optimize productivi- ty: A multi-crawler chassis is attached to the tripper car. The individually con- trolled crawler tracks allow movement in all directions without constraint. This system can be attached to any crawler to eliminate the wide steering radius com- monly required by conventional gearing systems that are normally attached to these machines. The system is designed to offer great- ly improved overall flexibility. As shown in the accompanying diagram, when the stacking bridge finishes a row, the tripper car will be at the bridge head or tail end. Before moving to the next row, the tripper car turns its crawlers 90° in the direction of bridge movement without impact on the system's performance. The tripper car moves in concert with the stacking bridge as an integrated stacking system. In the Yard The massive bauma 2019 trade show held earlier this year in Munich, Germany, provided a showcase for vendors to high- light not only new equipment, but new concepts in automated stockyard and port systems bulk material handling systems. For example, thyssenkrupp Industrial Solutions' full package comprises four components: Operator-less and remote operation – Ma- chines, with minor exceptions, included in thyssenkrupp's smart stockyard and port solutions will be fully automated; they can be remotely operated from a cen- tral control room, allowing the number of workers involved to be reduced because no direct human interaction or presence on the machinery is required. MINING EQUIPMENT LTD. "Rolling for more than 35 years" Mining Equipment continues to supply the tunneling and mining industries with top-quality rolling stock, Jetair fans and steel ventilation ducting as well as a large inventory of rebuilt equipment such as scooptrams, trucks, drill jumbos and other underground gear. Mining Equipment is based in Durango, Colorado and its main shop facility is in Farmington, New Mexico. And has steel fabrication capabilities near Shanghai. Mine Hoists International, a sister com- pany of Mining Equipment, is based in North Bay, Ontario. They boast the world's largest inventory of used mine hoist and large capacity stage winches for mining and shaft sinking projects. Their new 20,000 square foot shop in North Bay, Ontario can handle the largest of hoist and winch rebuilds. COMPANY PROFILE-PAID ADVERTISEMENT The lizard, a new and unique solution for heap leaching and dry tailings stacking, features a crawler-mounted tripper car that is decoupled from the conveyor bridge, which enables it to be controlled independently of the bridge. Supplier thyssenkrupp Industrial Solutions says the lizard pays off through a lower investment cost and fewer fatigue issues on the bridge structures.
