Predicting and Prolonging the Life of Used Cranes

by Feroze Vazifdar

So you have an older crane that has not undergone regular structural inspection—what are your options? You can do nothing and blindly use the crane, which, as we will explain later, is risky. Or you can assess its condition to find out how much structural life remains. Once you know the condition, you can decide how to best use the crane.

Liftech’s techniques of predicting and prolonging the structural life of used cranes are discussed in this paper. Liftech provided this service for quayside container cranes and rail mounted gantry cranes in Hongkong International Terminals, Hong Kong. These cranes will be presented as case studies.
