Spreader beams
Like lifting beams, spreader beams are also two-dimensional lifting beams. They are essentially subjected to buckling rather than bending and are therefore designed statically. This removes compressive forces from the load. Spreader beams can be lighter and cheaper than beam beams. The disadvantage is the significantly greater overall height of an spreader beam, but this greater overall height also reduces the swaying tendency and the load hangs more stably.
