Аннотация: The problem of improving the safety of the use of lifting machinery is particularly relevant for regions where intensive industrial and civil construction is carried out. To date, a significant amount of work has been done, designed at the theoretical level to justify the design and safe operation of lifting machinery. However, the existing methods of control of the total weight of the cargo transported by the lifting machinery are based mainly on the strain measurement methods developed in the second half of the twentieth century. The main disadvantage of systems that implement the strain measurement method is the need to integrate the weighing module directly into the design of the lifting machinery. A significant number of accidents of hoisting machines indicates the fuzzy operation of the protection systems of hoisting machines from overload, made on the basis of tensometric methods. As shown by the results of studies in the operation of various types of electric motors under load torque fluctuations occur at the rated speed. The use of this pattern allows weighing the cargo by the dynamic method transported by a lifting machinery. This article is devoted to the development and scientific and technical substantiation of the method of dynamic control of the weight of the cargo transported by the lifting machinery, based on the analysis of the dynamics of the angular accelerations of the rotor of the electric motor of the lifting drive.
