Strength of Materials and Theory of StructuresIncreasing the productivity of jib cranes is an urgent problem of improving their operation. Combining the work of separate mechanisms is one of the ways to increase the productivity of jib cranes. The aim of the study is to build a mathematical model and conduct a dynamic analysis of the crane jib system with simultaneous operation of the derricking ...
