Cranes and their components are not designed to last forever
Welded structures and machinery components experience fatigue and wear-and-tear whenever a crane is working. These components have a finite service life – which is correlated to usage, not calendar time.
Summary
- Design class determines usable design life
- Understanding the design life of your crane is critical
- Determining design life is especially important for older cranes
- Design life analysis is not just a matter of economics, it's industry standard
- Where to find expert analysis of the remaining design life of your crane
