Many thanks! We work for the same cause! After Mr. Duerr explains the mathematical formulas behind reliability, he emphasizes that "once a design provides a reliability of 99.9% for the given service conditions, any further increase in the design factor does nothing to improve the reliability or safety of the lifter". Calculation Sheet Lifting Set DNV 2 7 1 Stemar. 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). This efficient method of rigging redirects compression forces away from the load and in to the spreader bar.
