Abstract
Modern lifting machines have the ability to recover braking energy and therefore have high energy efficiency. However, the control systems of such machines are of considerable complexity and require the use of storage devices if they work in closed energy supply systems. The paper presents methods for increasing the efficiency of lifting devices at an early stage of design by partial balancing in order to equalize the load during ascent and descent. The technical solutions that can improve the efficiency of modern lifts and shaft elevator systems are presented.
