ALCOA Rockdale TX USA

Commissioned in 2005, this 19.3 km single flight conveyor was the longest conventional conveyor in the world. It also included one intermediate drive and 11 horizontal curves. In order to negotiate 11 horizontal curves, power was distributed between the head, tail, and halfway point on the conveyor. The intermediate drive is one of the first of its kind on a surface operation. We provided intermediate drive support as well as the control algorithms for starting and stopping.
