There are two other inflection points in the curve, one at a beam length of about 180 and another at a beam length of 255. 1A. An Overview of ASME BTH-1 (spreader bars and lifting beams) When planning to design lifting beams (or any other below-the-hook lifting devices), there are many aspects that must be considered beyond finding materials that meets a few basic engineering calculations. It checks the crane lifting capacity, tilt angle, and calculates the lift point load. Modulift modular spreader beams provide the ideal solution - versatile and cost-effective, the range has capacity from 2 to 3000t with spans up to 100m/330' About. Connect to a live classroom session virtually via a web link, with the ability to participate fully in the classroom dialogue, exercises, and Q&A. We work for the same cause! spreader bar calculations - josannebroersen.com .. Any recommendations? Generally, a spreader beam would not be as prone to the 'suspended beam' effect as a beam under its own self weight alone, since the end restraining torques for a given degree of rotation will generally be greater, (assuming that the lifted load is supended from lifting lugs located below the beam, and hence the lever arm of the couple is greater).
