Abstract: The paper describes the mathematical models of the drum-type winches and winches with a traction sheave. The presented mathematical models describe the dynamic processes in the asynchronous drive motor of the winch, and use the model of the asynchronous motor in the braked coordinate system. The presented mathematical model of winches is based on the solution of the equations of Electromechanical energy conversion, as well as on the solution of nonlinear differential equations of the equilibrium stress of circuits and moments by numerical methods. The paper presents a mathematical description of the mechanical part of the drum-type winches. When developing a ma-thematical description, the winches were considered as a two-mass systems. The mathematical model takes into account the rigidity of the system, the possible damping of the rope, the loss of Electromechanical energy, moments of inertia of the rotating masses, damping of the support surfaces, the weight of the winch support and the weight of the load, braking torque. A mathematical description of the mechanical part of the winch with a rope-carrying pulley is also presented. The mathematical model takes into account the occurring braking moment, the system stiffness, damping of the rope, the loss of mechanical energy, friction, moments of inertia forces of the rotating masses of the winch, the weight of the crate, the weight of the counterweight, the weight of the cargo-hoisting rope.
