Abstract

In this paper a method of calculus is presented step-by-step in order to establishing the residual lifetime of a lifting crane, using non-destructive methods of study. First it must be establish the actual state of machine and also areas subject to study, and then by applying the method it can be drawn the conclusion that at 2/3 of initial load can be reached an extension up to 5 times of actual residual lifetime.
