ResumoThis paper gives a proposal of one suitable concept for FEM structural modeling and analysis of cranes which are a common part of the waterway dredger facilities. These dredgers typically contain two cranes: main jib crane between the catamaran-like pontoons and auxiliary crane in the bow zone. Discussion here is dedicated towards advantages and weaknesses of various FE models for the crane structures, in order to avoid of frequently failures of serviceability state of a main crane. Basic goal is to emphasize the benefits of sophisticated but practical numerical model in comparison with the simpler and inadequate models for prediction of a real structural behavior of jib cranes. In that sense results of our research could be sort of template for FE modeling phase in an efficient design of such structures.
