Abstract: The object of the study is a load-lifting winch with a sectional-disc drum for single-row multi-layer laying of flexible elements, cargo cables and power cables, during their winding, electrically protected. The winch is intended for suspension and lifting and lowering of illuminated devices and equipment in closed rooms. In the process of research (constructive development, determination and analysis of parameters), the problem of creating a winch design of the specified type with a qualitatively increased overall level of functionality is solved according to the indicators: 1) electrical insulation, compactness and necessary strength of fastening of flexible elements, lifting cables and power cables on the drum; 2) controllability of the drive: in transitional periods – to ensure smooth acceleration-stopping of the suspension; in the period of constant movement – to ensure a constant speed of the suspension during raising and lowering. Electrical insulation between the power cable, the drum and other parts of the winch is created by using parts (discs) made of synthetic insulating material, for example, fiberglass, in the construction of the drum. Clamping of flexible elements between the disks in specially profiled C-shaped ring grooves, on the ends of the hub, of the disks ensures the necessary strength and compactness of the attachment. The smoothness of starting (stopping) of the drive and the constant speed of the suspension during the period of constant movement are established by adjusting the frequency converter in the drive control system according to the parameters determined by a specially developed methodology. The obtained results, constructive solutions and methods of research (estimation and analysis) of winch parameters can be used in the design of the structure and adjustment of the control system of lifting devices of this type.
