Gearless Drives for conveyors – capable of handling high power requirements and easy to maintain Together with Siemens, ThyssenKrupp has introduced a new highperformance generation of gearless, cycloconverter-fed ­ onveyor c drives. The principle has been proven for more than 25 years, with ongoing research and development. Its advantages are clear to see: fewer components, high ­ vailability, a reduced overall energy consumption, lower maintenance costs. Redefining power for conveyor drives Long conveyors with high throughput and steep height differences require a significant amount of power. When the demand for power exceeds three MW per pulley, Gearless Drive systems are the right solution. This system overcomes the restrictions attributed to gear reducers, and its gearless construction is simple, robust and easy to maintain. Cycloconverter technology has proven its high reliability over several decades. Conveyor belt suppliers are also able now to manufacture stronger belts (ST-10,000) that can withstand higher stresses resulting from higher drive power. In a word: The time to go gearless has come. Fewer components, longer conveyor Fewer high performance drives replacing many conventional ones: This formula makes longer conveyors more feasible and economical. With fewer components, the drive stations require smaller footprints. In underground applications, the number of expensive excavations are minimized. • igher plant availability by eliminating H e ­ lectrical components, couplings, gearboxes, associated bearings and lubrication systems – therefore minimizing the risk of downtime • p to four percent higher energy efficiency U achieved with gearless direct-drive technology • onger conveyors with fewer and smaller L drive stations, resulting in reduced excavations in underground applications ThyssenKrupp Robins, Inc. 6400 South Fiddler’s Green Circle, Suite 700 Greenwood Village, Colorado 80111 USA sales.tkri@thyssenkrupp.com www.thyssenkrupprobins.com ThyssenKrupp Fördertechnik GmbH Business Unit Mining ThyssenKrupp Allee 1 45143 Essen Germany info@tk-mining.com www.tk-mining.com Siemens AG Industry Sector Industry Solutions Mining Technologies Schuhstr. 60 91052 Erlangen Germany mining@siemens.com www.siemens.com/mining • igher power at the pulley – free H from traditional gearbox limitations • educe the potential for mechanical breakR downs by using more robust components • ewer spare parts resulting in less inventory F and lower capital investment • eduction of noise levels by eliminating R the reducer, the loudest part of a conventional drive station In cooperation with Siemens Gearless Conveyor Drives Synch.

Your challenge: Remote locations, longer distances, higher throughput, difficult maintenance conditions Your benefit: Move more ore. Save on energy. Save on maintenance costs. In many mining areas, ore grades are declining. New mines are being developed in more remote areas, pits are getting deeper and u ­ nderground mines are becoming larger. This means that more and more material must be transported over long distances and material handling poses new challenges. Which converter to use? Siemens offers two types of converters, each of which has its benefits. In Xstrata Copper’s Antapaccay...
