A pair of lifting eye assemblies are connected during the lifting operation at each respective end portion of the bar, each forming a connection with an above supporting bridle line and a depending lift line, each of the lifting eye assemblies comprising in part a socket of . Spreader and lifting beams are two popular pieces of lifting equipment. January 31, 2013 PVEng Fatigue design is not required for bars classified as service class 0 due to the low number of total load cycles, but as the number of load cycles is increased, the potential for fatigue failure increases. Decorate An Office On A Low Budget| Spreader bars for lifting and rigging consist of a beam with two or more lifting lugs on the bottom that attach to lifting slings that attach to the load. thenavalarch bears no responsibility for the accuracy of this article, or for any incidents/losses arising due to the use of the information in this article in any operation. sling tension calculations sling tension calculations (upper) weight and description of slings: (lower) weight and description of shackles: (all) weight of spreader bars: (upper .

The Dynamic Hook Load (DHL) is determined for this and using a simple mathematical formulation, the sling loads are determined. Rig your spreader beam correctly As an example, if you were to hoist a large rectangular load, the safest way to set the chains or slings is to have a two leg chain sling below each end of the spreader beam lifting points. We can see that the vertical downward forces of Fv1 and Fv2 are balanced by the components F1y and F2y, while F1x and F2x are the compressive forces on the spreader. For lifting beams that are subject to flexure, ASME BTH-1 has calculations that define the maximum allowable bending stress based on beam geometry, material properties, and lateral bracing spacing (the distance between braces that resist lateral displacement of the compression flange or twisting of the beam cross-section).
