Company Profile–Paid Advertisement Siemens is a global technology power- house that has stood for engineering excellence, innovation, quality and reli- ability for more than 165 years. The com- pany is active in nearly all countries of the world focusing on the areas of electri- fication, automation and digitalization. Drive your mining business with Siemens For over 40 years, Siemens has partnered with leading equipment manufacturers to develop innovative systems for the mining industry. As one of the major suppliers of the global mining industry, Siemens offers a comprehensive solutions portfolio that enables customers to effectively meet their challenges – at each process stage, from extraction to transportation and benefici- ation. With our integrated approach and profound industry expertise, we improve your overall plant performance and secure long-term competitiveness. Shovels – For four decades, Siemens has been the leader in innovative AC drives for electric rope shovels. Today, our solution is the model for Integrated Drive Systems – in- corporating rugged traction grade drives and motors, which are coupled through mechanical drives, monitored and con- trolled by process control software and optimized through innovative technolo- gy spanning from energy storage devices to remote monitoring and autonomy. Draglines – Developed from a shared common plat- form with our electric rope shovel drives, our AC drives for draglines provide the same reliability, productivity, efficiency and safety benefits. With up to 20 percent efficiency increases over motor-generator sets, our drives define the benchmark in the market. Siemens innovations, such as the gearless drive reduce operating costs even more, eliminating the need for gear maintenance and lubrication systems. Haul trucks – Siemens offers the most powerful electric truck drive available on the market. Our combination of high torque, high power and ease of operations in an AC drive sys- tem translates into increased payloads, shorter cycle times and higher system reliability. Proven converter technology, integrated drive train and innovative re- mote monitoring and management tools minimize lifecycle costs. Underground vehicles – Expanding our solutions portfolio for the mining industry, Siemens introduces a new drive system for underground min- ing vehicles. The high-efficiency electric drive system includes Siemens robust and proven propulsion and auxiliary inverters, established control hardware and software as well as optional energy storage solutions. At the heart of Sie- mens' drive train is the high-efficiency PEM Motor typically connected to the wheels with a planetary gearbox. This PEM motor, which is suitable for diffi- cult mining conditions, achieves up to 97 percent efficiency compared to the lower efficiency of standard induction motors of similar size. With these components working together, the haul truck's brak- ing energy can be intelligently harnessed and stored for electric propulsion. As a trusted mining partner, we help our customers efficiently meet their needs and enable them to set new bench- marks within their fields.
