It calculates the design load, the Dynamic Amplification Factor (DAF), and point loads for slings above and below spreader. 4. The allowable bending stress is a product of calculations from BTH-1, and the lift capacity is calculated from the allowable bending stress. ECONOMICAL LIFTING BEAMS Adjustable Spreader/Lifting Beam (ASLB16) Rated Cap. 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). Design of steel column & runway beam. This lifting force is transferred to the sling by a shackle put through the padeye pinhole, creating a pinned connection.
