Bauxite Reclaimer Bridge Chord Repair

The client has a reclaimer that has been operating for over ten years at its facility in South America.  This equipment experienced chronic fatigue cracking in the truss beam upper chord.  After making in-house crack repairs and performing a modification that resulted in further fatigue cracking, the client retained Liftech to evaluate the cracking and to design repairs.

Liftech performed analyses that determined the cause of cracking and developed a simple repair detail that improves fatigue performance by a factor of 20 to 400 depending on the loading condition.  Liftech provided a report summarizing our review, the cause of cracking, and our recommendations, repair design drawings, and procedure.
