Quintette Project
Quintette Project Analysis and Design - The overall system was experiencing controlled braking runaways, gear reducer and pulley failures, and numerous other problems. CDI was contracted to identify, analyze, and correct the problems. The project services included pulley design, dynamic analysis, brake system design, instrumentation, and control system design. The control system design included the logic development, programming (Allen Bradley PLC2/30), on-site commissioning and performance testing. The project included a 13 Km route with 7 Km and a 6 Km downhill conveyors.
