Abstract

The oscillations of the crane, especially the pendulum motion of the lifted load suspended from rope, makes the load positioning operation difficult. endangers the potential stability of the crane and the dynamic forces, due to their oscillating feature, lead to fatigue damage of structure components. On the other hand, it is not possible to perform a fatigue analysis without the knowledge of the so-called stress-time histories. All this requires the application of dynamic analysis methods. This paper is intended -through the analysis of transient motions and loading of a lattice type mast structure of a tower crane to show the possibilities of computer simulation of dynamic loads and stresses and in promotion of the crane design.
