Abstract
In this paper, we study the dynamic loads acting on the ropes of the SOKIL portal crane lifting drive during the overload of forest logs according to the «warehouse-ship» scheme in a river port. An electrotensometric method was used to analyze the nature of changes in dynamic forces in the drive elements. The analysis shows that the dynamic loads in the lifting drive of portal grab cranes, which have been in operation for more than four decades, are insufficiently studied. It should be emphasized that each crane requires an individual approach to research, since the dynamic parameters of its mechanisms are significantly affected by operating conditions, geometric characteristics, as well as physical and mechanical properties. The results obtained indicate that when loading loads weighing from 11 to 15 tons, the dynamic force coefficients in traction ropes range from 1.18 to 2.45. the dependence of these coefficients on the weight of the load is nonlinear..
