Fine Ore Cusher – 7B Conveyor Counterweight Evaluation

Southeast, AZ

The existing counterweight on the 7B conveyor had a winch system with inadequate lug connections and was rigged at an improper angle, which created structural integrity issues. Bowman calculated the take-up weight on lateral beams to size counterweight box and evaluated counterweight lifting methods compared to the existing winch system. Bowman prepared an economic trade-off study and general arrangements for counterweight lifting methods.
