work is devoted to the study of the electric drive of overhead cranes and the creation of a new reliable system of a multi-motor electric drive with a coordinated rotation of the speeds of the drive motors of the movement mechanisms of overhead cranes. The electromechanical travel system of an overhead crane is a complex multi-mass elastically connected system controlled by a multi-motor electric drive, which is subject to a large number of force factors. The main trends in the development of the electric drive of overhead cranes are to increase the reliability of its operation and the range of speed control. The study of the electromechanical system of the mechanism of movement of the crane bridge indicates that the metal structure of the crane is subject to dangerous elastic transverse deformations, the limitation of which can be ensured by optimizing the electric drive system. For overhead technological cranes, the most promising is the use of a coordinated rotation system in the electric drive of the crane movement mechanism based on the principle of an electric working shaft.
