The dead load does not include the self-weight of the beam. For the purpose of this calculation, the lifting beam will be analyzed using a single point at the center of the beam, with fixed ends. The sling wire transfers the load to the lifting beam. Spreader Beam: A below-the-hook lifting device that utilizes two or more hooks (attaching devices) located along a beam and the spreader beam attaches to the hoist by means of a bail. A. Dr. n Important that loads be hoisted above the load's CG. Once the lift has been classified and determined to be an ordinary or incidental lift, use.

A beam lifting cracking limit state is developed based on analytical equations for calculating the roll angle of the beam, the internal forces and moments, the weak- axis and strong-axis deflections, and the cross-sectional angle of twist.

In this case, the lifting beam is subjected to 1000 tonnes (Note: the two pad eyes that transfer the load is subjected to 500 tonnes each).
