The invention relates to a method used for influencing movement of a load, the load is suspended on a crane so that at least one of at least four crane suspension points arranged on the crane is connected with one of at least four load suspension points arranged on the load through at elast one rope type fixing device, the fixing devices are connected with adjusting devices, the length of the fixing devices between the suspension points can be separately changed through the adjusting devices, an optical detection device is arranged on the crane, a rotation angle and/or at least one time derivative of the rotation angle of the load can be detected through the detection device when the load performs rotational motion around a vertical axis, the rotation angle and/or the derivatives are detected, a rated value used for the adjusting devices is calculated by use of a mathematical model under the condition of taking into account the geometrical shape of a load suspension structure, and the adjusting devices are controlled to reach the rated value. The invention also relates to a crane.
