Dockside cranes must retain adequate strength requirements that will not endanger the safety of their use. This may cause the fact that the impact of vibration on the structure exposed to horizontal forces caused by the transport of goods loading and transverse forces caused by wind can be dangerous for the correct operation of the machine. In addition, there are often consequences of climate-related environment, with fatigue - dynamizującymi destruction of the object. Dynamic loads may cause effects so devastating or catastrophic lead to their destruction [1,6,9,13,21]. Recognizing the need to improve methods for testing of lifting equipment for the purpose of assessing their condition and assess the safety factors in this paper attempts to study the destruction of the structural element of the lift with the help of theoretical methods of modal analysis [4,8,12,21].
