DYNAMIC PROBLEMS INVOLVED IN OPERATION OF SELECTED ELEMENTS OF CRANE INSTALLATIONS USED IN THE FOUNDRY ENGINEERING

摘要

In his paper is pre presented an effort of realistic assessment of loading of some element of a traveling crane. Dynamic analysis of operation of a system – crane beam – crane – crab has been made for possible phases of a crane operation. This made possible, for analytic formulae presentation which determine real loads of particular elements of a considered system. Obtained relations may be useful for dimensioning and exploitation safety assessment of such structures.
