Abstract
A device for controlling a swinging of a load suspended from a motorized slidable element is described. The controlling device includes a control unit and an inertial platform. The control unit is provided with means to measure and control the speed of the motorized slidable element and is able to process the values representative of the inclination angle of the cable with respect to the vertical to calculate and to impart control actions in order to dynamically control the speed of the motorized slidable element as a function of a desired inclination angle of the cable with respect to the vertical.
