Based on the analysis of the development mining and coal industries trends, including mine lifting units, the expediency of introducing new modern electric drive systems capable of ensuring high accuracy of working out the given movement law of the lifting vessels is determined. Based on the model of the cargo lifting installation electromechanical system, researches of the level of working out a given speed accuracy at the point of loaded skip entry into the unloading curves with variations of the load value and the degree of balancing are made. The analysis of the obtained research results is performed and the feasibility of using electric drive systems with induction vector-driven electric motors with existing mine lifting installations is substantiated.
