A New Approach for Dynamic Analysis of Overhead Crane Systems Under Moving Loads

Nowadays, dynamic effects of overhead cranes are usually neglected because of their operation at low speed but they can be designed considering the static effects. However, the production rate increases with the development of technology and the increase in the number of proper places for product handling and cargo ships loading in the harbour. So the need for working cranes is growing. Therefore, in this study we have analysed both single bridge and double bridges crane systems and the load dynamic effects occurring on the bridge during the movement of carriages. The analysis was based on the Finite Element Method (FEM). The conclusion of the study was that double bridge cranes have had less dynamic effects under the same loads as single bridge cranes so they proved to be working faster.
