Dynamic factor lifting
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. WebLifting and spreader beams In daily practice, we frequently mix up the terms ‘lifting beams’ and ‘spreaders’. The difference is that a lifting beam is a device that helps guide the lifting slings from the lifting points of the load towards the hook block, whereby a set of shackles are fitted to the lifting beam to connect the slings from

WebMay 2, 1976 · A simple spring model of a luffing crane has been used to derive the magnitude of the maximum dynamic factor which occurs when a load undergoing sinusoidal motion is lifted. This factor depends on the magnitude of the load lifted, the wave parameters and the crane stiffness. WebThus a dynamic amplification factor (DAF) is applied to the physical system so that the possibility of sling snap does not occur. This value of DAF can be obtained from the DNV …
