【 摘 要 】

The paper deals with the impact of the controlling system adjustment on the level of the dynamic loads operating on the hoisting machine parts during the period of the non-steady motion. The impact of the operating regime of the hoisting machine generalized mechanism on the consistency of operation and the variation of the parameters of the mechanism controlling system with the electric drive and frequency converter is experimentally shown. The procedure of the experiment is described; there are given the comparative results of the variation of the mechanism performance when it works using the controlling system with the frequency converter and brake resistor, and without it, when working on the natural parameters. There are conclusions about adequacy of the normative method for the dynamic coefficient option, determining the loading of the hoisting machine metalware, and in case of occurrence of adjustment errors in the frequency converter controlling system.
