A new alternating current (AC) excavator system launched by GE Energy is set to offer surface mine operators a complete electrical drive solution for heavy equipment.

The company says mining operators are finding it increasingly difficult to deliver the same amount of minerals in the same time with existing technologies, as sites mature and ore becomes lower in mineral concentration. GE says this is forcing companies to seek more energy efficient and reliable solutions.

Its new AC excavator solution is made up of drives, controls and motors designed specifically for challenging surface mine applications and environments.

“Mining owners and operators are migrating to AC systems in general,” said GE’s senior product manager Nimesh Sharan. “AC excavator systems are more energy efficient, and because they utilize less mechanical parts, AC systems tend to require less personal care and maintenance.”

GE’s AC excavator solution is a complete electrical drive solution comprised of a family of AC motors, drives, controls, engineering and field services. Heavy equipment original equipment manufacturers and earthmoving equipment owners can apply this solution in their draglines, shovels and blast-hole drills. GE says this will offer mining operators huge advances in terms of lower cost per material tonne moved.

The company’s senior marketing manager Justin Forbes says, “Our solution offering is truly unique in the industry. GE’s end-to-end solution includes up-front application engineering, rugged, field-tested equipment and field engineering support for installations.”

GE has a long history of designing, installing and maintaining direct current excavator systems across the globe. Business arm GE Mining Solutions was established to collaboratively develop with clients the technologies needed to continue their success despite the challenges of mining deeper and in more remote locations brought about by increased demand for minerals.

The company continues to invest in new technology solutions and grow through strategic acquisitions to strengthen its local presence and better serve customers around the world.

Its businesses comprise GE Power & Water, GE Energy Management and GE Oil & Gas with more than 90,000 global employees and 2010 revenues of $38 billion. The company prides itself on providing integrated product and service solutions in all areas of the energy industry including coal, oil, natural gas and nuclear energy; renewable resources such as water, wind, solar and biogas; as well as other alternative fuels and new grid modernization technologies to meet 21st Century energy needs.
