Method for driving crane by selecting and applying preferential load curve depending on inclination of cantilever structural element

A crane driving method for selecting and applying a preferential load curve suitable for the working configuration of a crane comprising a mast supporting a lifting boom comprising at least one boom structural element, said crane driving method implementing: a gradient measurement step, the measuring device is used for measuring the actual inclination of the cantilever structural element relative to a reference axis in a working structure by means of an inclinometer mounted on the cantilever structural element; a selection step of performing an automatic selection of a preferential load curve selected from a plurality of load curves stored in a memory and calculated in advance for a number of gradients of the cantilever structural element according to the actual gradient of the cantilever structural element; and a driving step implementing the application of said preferential load curve for the manipulation of lifting and moving the load along the lifting boom in the working configuration of the crane. 一种起重机驱
