Combines over 25 years of Siemens AC shovel drive experience with innovative IGBT technology. The system allows for higher stall torque, faster acceleration, and higher speeds in field weakening. It operates routinely at over 98% availability and requires no routine maintenance. Future-oriented gearless technology delivers productivity gains of up to 20% and approximately 20% higher efficiency, and minimizes maintenance requirements.
Increased excavation quality with maximum availability: power shovel in use at Athabasca Tar Sands, Canada
In 2002, Siemens equipped the shovel excavators at the Athabasca Tar Sands mine with three-phase IGBT drives and data acquisition systems as a part of a SIMINE SH package. Since then, average availability of the machinery has been 98%. The integrated data acquisition system includes diagnostic tools, real-time monitoring of the machines and a payload system for blending. A crucial advantage is the ability to detect and control the quality of the excavated material.
