1988 Kennecott – Bingham Canyon United States After startup, the drum of a tensioner pulley failed in the housing. CDI was not involved in the design of the pulley. CDI investigated the failure of the shell and determined that the shell is sub-designed. An engineering audit of the remaining pulleys was performed, using the CDI failure criteria, and similar deficiencies were found in the high tension pulleys. These pulleys failed three months after our audit.
