![]() Therefore, to speed up this process Eager.one has developed a handwritten code, applicable to run different configurations at the same time, without the need for re-modelling. However, this is not a quick process, especially when it comes to many different configurations of a crane. Historically, these calculations are done by “nonlinear” FEM (finite element method). Additional longitudinal bending due to change of shapeįor every boom-, jib length and lifting radius it requires a cyclic (nonlinear) calculation to predict the deformations.Additional side-ward bending moment due to change of shape.Additional loads on the crane induced by geometrical changes.What does this mean for the determination and calculation of the crane capacity? Since the 2 nd order effect increases for slender (high) cranes, calculations get more complex and more time-consuming due to its non-linear (cyclic) character. Cranes are getting higher with increased slenderness as a result.
