The following chart shows a comparison of a W-Beam lifting beam with lifting capacity based on simple bending stress calculations vs calculations that account for buckling per ASME BTH-1. These items are discussed in more detail below. The spreader beam discussed here is one with two lifting points, from which the lifting slings go vertically straight down to the lashing points on the cargo as shown in the figure below: At the outset, it is important to clarify the difference between a spreader and a lifting beam. LUG DESIGN XLS Scribd. Part 46 of Mine Safety and Health Administration (MSHA) regulations requires that new miners complete no less than 4 hours of training before they enter a mine site and that all miners take refresher training on an annual basis. This type of lift subjects the beam to flexure (bending) and shear, with bending stress and lateral torsional buckling being the primary modes of failure. 2007-2023 MoreVision Ltd.

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. steel . Note: According to ASME B30.20, proof testing is only a recommendation, not a requirement. According to BTH-1 calculations, the short beam can be loaded to full yield strength (accounting for safety factors), but as the beam length (or lifting spread) increases, the stress reaches an inflection point where the allowable bending stress starts to drop off. We partner with organizations to assess, transform, and continuously improve their hoisting and material handling activities by adapting and applying our structured methodology, expertise and solutions. 1 DESIGN DATA. Lifting beams / Spreader beams can be designed and made for general use or as bespoke one-offs for specific lifts . In the slide below, Duerr explains that if the strength of the material and the load's weight was known "exactly", a known design factor would be a fitting, practical solution for our project.
