How much time does your crane have left?

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. Frequent inspections, while necessary, cannot always catch machinery failure that may be caused by extremely fast crack propagation. A calculation of design life will give information that helps you assess your safe working limits and plan actions for continued equipment use.
