Abstract

The design of lifting equipment involves many different aspects. In general, according to recent standards, actions must be considered constant over time. To include the dynamic effect induced by moving payloads (vertical or translational), the forces were increased using a specific coefficient. The same procedure was implemented for many other situations, such as wind forces or wave-induced actions. However, the real situation is very different; in fact, time-variable actions induce many effects on the structures, which can lead to damage or collapse of the equipment. This can include overturning (especially for cranes), global or local buckling, fatigue phenomena, etc. Another important issue is that if the machine is subjected to vibration, the entire system for using the equipment must be taken into account. For example, the time needed to attach and detach the payload increases, thus reducing the efficiency of the system. The focus of this mini-symposium concerns the analytical, numerical, or experimental study of dynamic actions on lifting, moving, and hoisting equipment, the response of the structures, and the methodologies to avoid or reduce these dynamic effects. The main point of this mini-symposia is the study the dynamic behavior of lifting equipment such as cranes (all types), vibration, cableways, rail transport, and so on.
