Stress Analysis of Jib, Counterjib and Hook of tower crane: A Review

Mechanical Engineering

Cranes are transport machines, which generally used in heavy machinery industry, shipyards, seaports, warehouses and construction sector. There are several factors that have to be taken into consideration when a crane being designed. Most important factors are; own weight of the crane, the weight of the bulk which has to be transported and the dynamic loads which occur during the movements. Moreover, for the cranes which operate in open-air, the external loads caused by wind and the other climate conditions have to be considered. In order to prevent possible accidents which can cause enormous losses after manufacturing, all these factors have to be taken into account during the design process. That means crane design process requires repetitive strength calculations. During the design process, time can be saved by handling these calculations with the assistance of Finite Element Method. In this study; results of the analytical calculation and the results that were obtained by finite element method have been compared. In this way, it has been investigated the reliability of the finite element method for JIB crane design. As a result, it has been seen that, F.E.M is the most practical and reliable method which can be utilized during JIB crane design process.
