Crane Useful Life Assessment and Maintenance

by Feroze Vazifdar
Presented at the TOC Asia 2005 Conference in Hong Kong

This presentation discusses fatigue design philosophy, useful life analysis, structural maintenance, and shows repair examples.

Fatigue cracks occur and can be catastrophic if not repaired in time. Cracking can be controlled with proper design, workmanship, quality control, and a proper structural maintenance program. Structural useful life analysis can be used to predict future cracking so the owner can decide the best course of action.

This article discusses the rationale behind structural maintenance programs for cranes.
