MINERS GUIDE TO BAUMA 46 E&MJ • MARCH 2019 seamless tube with a 32-mm diameter. The thread is ISO R32 rolled with uneven length from each side. The material for the SDDB Nevada type has been carefully selected to respond to a customer's inquiry for yield load and elongation at break. The bolt is typically used for single length applications although it can be extended with couplings to reach the desired length where neces- sary. This anchor utilizes a drill bit and lon- ger root threaded section for anchorage. Scania's V8 Celebrates 50 Years Scania will display five construction trucks in total: four inside the exhibition hall and one outside it. What they all have in common is the robustness and produc- tivity level for which Scania is well known. At bauma, Scania is also showing con- nected engines for equipment, vehicles and vessels that facilitate fleet monitor- ing and optimized uptime. This service is based on the vast knowledge Scania has gained from having connected 350,000 buses and trucks. The company is also celebrating the Scania V8 turning 50. It made its debut back in 1969. "In its latest edition, it is still the pre-eminent solution, always delivering like no other," Alexander Vlas- kamp, senior vice president of sales and marketing. "Regardless if it's emotion or logic behind a purchase, the V8s never let our customers down." Conveyor Components Superior Industries (Hall B2, Stand 107), an American builder of crushing, screen- ing, washing and conveying equipment, said its presence at bauma 2019 will be three times larger than previous editions. In addition to wet processing equipment, Superior will display conveyor compo- nents, including the Chevron Pulley, a V-shaped wing pulley that deflects oncom- ing rocks; the Moxie Roll, an idler made from a composite blend, which are 50% lighter and at least three times quieter than steel; the High Performance DT Idler for improved performance in high capaci- ty applications; and the Exterra SFL Dual Belt Cleaner, a primary and secondary scraper sharing one mounting pole. Mobile-stacking Bridge thyssenkrupp Industrial Solutions will pres- ent its new mobile stacking bridge, "the liz- ard." This unique solution for heap leach- ing and dry tailings stacking combines two proven technologies — the conveyor bridge and the tripper car — in a new way. The liz- ard decouples the crawler-mounted tripper car from the conveyor bridge, enabling it to be controlled independently of the bridge. Decoupling the tripper car from the conveyor bridge has several advantages: The transitions between the bridge seg- ments are easier as there is no stress from a traveling tripper car on top of the bridge. As the loads on the bridge sink, the overall construction of the bridge out- weighs the additional chassis and struc- ture of the tripper car. This way the prod- uct saves weight and costs, according to the company. In addition, a larger dump height and longer outreach are possible. "Especially with longer conveyor bridge systems the lizard pays off with lower in- vestment cost and less fatigue issues on the bridge structures," said Stefan Ebert, global product lifecycle manager. "Since the tripper car is not traveling on the bridge, the loads for dimensioning the bridge are significantly reduced," said Burhan Os- mani, engineer at thyssenkrupp Industrial Solutions and the inventor of the lizard. Operators benefit from a slimmer, lighter bridge structure, lower bridge height, smaller bridge crawlers and low- er ground pressure. The same lightweight design can also be used for the reclaiming bridge. Fatigue issues otherwise caused by cyclic loads from the tripper car are completely eliminated, the company said. Scania will display five trucks at bauma. The lizard mobile-stacking bridge from thyssenkrupp Industrial Solutions can be used for stacking ore on the leach pad and tailings.
