A method for controlling command of lifting a load suspended from a boom, carried by a mast of a crane, includes determining: depending on the mass of the suspended load, a specified load factor quantifying an acceptable exceedance with respect to a predetermined maximum allowable load for said crane; a maximum permitted lifting acceleration, depending on the mass of the suspended load, on the specified load factor and on the distribution position of the load suspended on the boom with respect to the mast; from lifting speed setpoints, optimized lifting speed setpoints intended to be executed by a motor device for displacing the suspended load according to a lifting movement so that the acceleration related to the lifting movement remains, in absolute value, less than or equal to the maximum permitted acceleration.
