This is a research about crawler cranes operating with full load in order to determine the risk of overturning. The case of crane motion is boom luffing. The method of analysis is the comparison of results gained through modeling and simulation and experimental measurements. It is well known that boom motion at crawler cranes is followed by heavy oscillations mainly caused by load stvinging, which passes to the boom and other parts of the crane. This occurrence can create problems with stability, load drop and crane overturning. The main focus is the study of dynamic stability, overturning moment and forces in some parts of the crane. Overturning moment is the main stability parameter in these cranes and depends on mass as well as on geometric and kinematic parameters. This moment will be compared to the static moment, and the exact position of the boom will be searched where overturning can happen. The results gained from the simulations will be presented in graphical form. Also, they will be compared to the results from experimental measurements. [ABSTRACT FROM AUTHOR] |
