The aim of this project is to check how far the existing guidelines for dimensioning the supporting framework of cranes can be improved, to increase the reliability of the equipment by introducing appropriate measures at the design and dimensioning stage. In the first project stage, measurements were taken under service conditions on a crane located in the finishing shop of a round-section casting plant. The transport operation, the equipment load and the stress on the supporting framework were recorded. The second stage involved the theoretical analysis of material handling, design loads, stresses and reliability, based on production data. This resulted in the following proposals : 1.The required operation of the crane equipment should be stated at the design stage, supported by material handling diagrams and typical transport examples, and the design loads should be based on this information. 2.The stress distributions should be examined, eg by using finite-element models 3.Stress analysis can be simplified, particularly by linking the facilities of CAD systems with finite-element software packages.
