摘要
This defining method (100) comprises the steps of: - simulating a crane (1) comprising: i) a boom (2) made up of elements (5) and ii) a lifting member (8) that is able to move along the boom, - selecting several elements (6) to be tested, maximum stresses, and several ranges (L) along the boom (2), and - carrying out the following analysis steps of: • choosing a theoretical load, • calculating stresses brought about by the theoretical load in each element (6) to be tested, • comparing these stresses with maximum stresses, • increasing or decreasing the theoretical load depending on whether stresses are less than or greater than the maximum stresses, • repeating the calculating step and the comparison step and the step of increasing or decreasing until the maximum theoretical load is found, and • recording i) the range (L) and ii) the maximum theoretical load.
