What is Design Life Analysis,and why does it matter

The likelihood of such failure increases closer to the end of the design life of your crane.Konecranes Design Life Analysis gives crane owners an overview on how much more use they can expect from their equipment.Remember,cranes do not exhaust their life in calendar time,but in relation to work cycles and running hours.Trasna Engineering - Port Cranes Dynamic StructuresTrasna Engineering Ltd.is an engineering services office based in Europe providing independent inspection,analysis and assessment solutions towards ensuring of structural integrity to clients in the heavy engineering sector with a particular emphasis on Port Container Cranes and other dynamic structures.Trasna Engineering - Port Cranes Dynamic StructuresTrasna Engineering Ltd.is an engineering services office based in Europe providing independent inspection,analysis and assessment solutions towards ensuring of structural integrity to clients in the heavy engineering sector with a particular emphasis on Port Container Cranes and other dynamic structures.

Portal frames - SteelConstructionfo

Portal frames are generally low-rise structures,comprising columns and horizontal or pitched rafters,connected by moment-resisting connections.Resistance to lateral and vertical actions is provided by the rigidity of the connections and the bending stiffness of the members,which is increased by a suitable haunch or deepening of the rafter sections.Multi-scale fatigue damage model for steel structures The validity of the developed multi-scale damage model is verified by comparing the predicted damage evolution curve with the experimental data.It shows that the developed model is effectiveness.Finally,the fatigue analysis on steel crane runway girders (CRGs) of industrial steel melt shop is performed based on the developed model.Movement identification model of port container crane The cranes health monitoring analysis studies are less compared to other different structures studies; refer to (Deng and Xu 2009,Bhimani and Soaderberg 2010,Zhiping et al .2011,Ding et al
