Cranes are getting higher with increased slenderness as a result. What does this mean for the determination and calculation of the crane capacity? Since the 2nd order effect increases for slender (high) cranes, calculations get more complex and more time consuming due to its non-linear (cyclic) character.
For every boom-, jib length and lifting radius it requires a cyclic (nonlinear) calculation to predict the deformations. Historically these calculations are done by “nonlinear” FEM (finite element method). However, this is not a quick process, especially when it comes to many different configurations of a crane.
Therefore, to speed up this process Eager.one has developed a hand written code, applicable to run different configurations at the same time, without the need for re-modelling.
Eager.sterk© is our in-house design software to calculate capacity charts for all kinds of cranes, independent from any brand.
Do you need 10-15% more capacity in the chart? We can help you!
Our engineers work with STERK© to calculate the limits in crane design. We will research your crane structure in order to find the weakest spot. With this information we can advise you for reinforcements of the crane to increase the strength. This maximizes the crane capacity within the required safety standards.
