Question about spreader beam unbraced length
Question about spreader beam unbraced length
(OP)
I'm reading David T. Ricker's "Design and Construction of Lifting Beams" and read on page 153 that "The unsupported length of a lifting beam is the length between the outermost lifting holes." Why wouldn't the unbraced length be the entire length of the beam regardless of where the lifting points are located?






RE: Question about spreader beam unbraced length
If you consider the lifting beam to be a three point lift ie:- the 2 lifting holes to be the simple supports and the load being lifted in the middle and draw the shear force and
bending moment diagrams you will see there is no bending moment or shear force outside of the extreme lifting holes.
