Dynamic analysis of the simultaneous movement of the jib lifting and crane turning mechanisms
Strength of Materials and Theory of StructuresThe efficiency of jib cranes largely depends on increasing their productivity when performing loading, unloading, and installation operations. The simultaneous operation of individual mechanisms increases the productivity of jib cranes. The purpose of this study is to construct a mathematical model and perform a dynamic analysis of the crane jib system
