WebJul 1, 2011 · The dynamic factor is the ratio of the maximum dynamic load to the static load acting on the wire ropes between the boom of a floating crane and a cargo. In this paper, the dynamic factor is analyzed based on dynamic simulations of a floating crane and a cargo, considering an elastic boom. Webφ i is the dynamic factor, see Table 2.1; F k is the characteristic static component of a crane action. (5) The various dynamic factors and their application are listed in Table 2.1. (6) The simultaneity of the crane load components may be taken into account by considering groups of loads as identified in Table 2.2.
