This defining method comprises the steps of: &#x2014;simulating a crane comprising: i) a boom made up of elements and ii) a lifting member that is able to move along the boom, &#x2014;selecting several elements to be tested, maximum stresses, and several ranges along the boom, and &#x2014;carrying out the following analysis steps of: &#x2022;choosing a theoretical load, &#x2022;calculating stresses brought about by the theoretical load in each element to be tested, &#x2022;comparing these stresses with maximum stresses, &#x2022;increasing or decreasing the theoretical load depending on whether stresses are less than or greater than the maximum stresses, &#x2022;repeating the calculating step and the comparison step and the step of increasing or decreasing until the maximum theoretical load is found, and &#x2022;recording i) the range and ii) the maximum theoretical load.
