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. Webeps-gulf.com
WebWhen it passes through the splash-zone, it experiences hydrodynamic forces that cause the object to undergo heave and pitch motion. This causes the lifting slings to undergo alternating motions of loosening and tensioning.
