BTH-1 includes a structural design section covering fatigue requirements for lifting devices classified as service classes 1 through 5. The bending calculations include bar weight, but do not account for shear stresses. These points are where calculations switch according to BTH-1, due to the beam length (There are several different calculations for allowable stress which are dependent on the beam properties and beam length, with different calculations for different lengths of beams). The stiffer the arms, the less bend you need. Spreader bar lifting device calculations and design jobs Steve I am just reviewing this calculation now.
