They are not discussed in this article because they do not generally apply to typical spreader bars and lifting beams. 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. The lift capacity of the beam is calculated based on the allowable stress (Orange Plot) and beam length. Though, because of many factors, structural design factors are benchmarked at different levels in design standards around the world. Spreader beams are some of the most popular below the hook lifting devices in the material handling industry. Can I take more that one course at a time? 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). Spreader bars, lifting beams, and other below-the-hook lifting devices are classified based on the frequency and capacity of lifts that are required of the device. . In other words, a below-the-hook (BTH) lifting device is a tool or mechanical device that attaches to a crane or other lifting apparatus, and grabs and secures a load so that it can be moved safely from one location to another. 1A. description of load: max.
