TLANTA, Georgia – Siemens Industry has won its largest mobile mining order from Hitachi Construction Truck Machinery to provide 50 more EH4500 trucks equipeed with Siemens’ AC drive technology. The trucks will be delivered to Indonesian-based Kaltim Prima Coal to join the existing fleet of 79 EH4500 trucks.

Unlike conventional DC drive technology, AC drives require virtually no maintenance because of their brushless operation. Siemens AC drives also provide higher top speeds and better gradeability.

In addition, the Siemens technology incorporates several patented safety features such as anti-rollback, which prevents trucks from rolling back on inclines, and slip-slide control, which helps control skidding in wet weather conditions. Another key attribute is the cruise control feature.

Siemens will also provide a permanent on-site service team to assist with the initial operation and long term reliability of the machines. The trucks are expected to be fully operational by December 2012.
