The purpose of the work - to improve the design and technological preparation for the production of hoisting and transport, construction and mining machines is possible on the basis of a comprehensive analysis of existing machine designs and technologies and the development of new modern methods to improve their technical level. Research methods - theoretical research on mathematical models using the mathematical package Maple, Excel spreadsheet, etc., Experimental research on laboratory installations using strain gauge equipment. Theoretical and practical results: 1. Theoretical and experimental studies have shown that the use of spring-wave gearbox will significantly reduce the coefficient of dynamism in the operation of the lifting mechanism. In the course of further research it is planned to improve the developed design of the gearbox, to conduct research in order to select the optimal design performance from the condition of minimizing the coefficient of dynamism. 2. The obtained results of calculations for start-up conditions show that the nature of the change in skew approximately corresponds to the case of braking. However (including for forced start-up, when the traction forces developed by the engines reach the maximum possible value), the dynamic loads during the skew of the braking periods significantly exceed the starting and are therefore in most cases calculated. 3. The physical model which allows to carry out leveling tests of various designs of leveling devices and schemes of hoists, with a possibility of change of loadings, and full similarity to the prototype foundry crane is created. 4. The analysis shows that with the use of different modes of surfacing of one material Steel 30HGSA time can be reduced more than twice, while energy consumption increases by 10%.
