Bingham Project – Provided the design criteria and mechanical specifications for all components for a 9 km overland system, as a consultant to Ralph M. Parsons Co. Provided the mechanical design support to PHB Wessehutte, including head-tail 6000 hp drive (4 x 1500 hp) wound rotor motor control / logic, and head-tail brake PLC logic code for the system of four large conveyors. Subsequent to commissioning, a PWH takeup pulley failed in the shell. CDI was not involved in the pulley design. CDI investigated the shell failure and determined the shell to be under-designed. Provided engineering audit of remaining pulleys, using CDI failure criteria, and found similar shell flaws on high tension assemblies. These pulleys failed within three months of our audit.
