However, unlike the spreader beam, the lifting beam usually has a single attachment point (at the topside) that attaches to the crane’s hook. This orientation causes the spreader beams to convert loads into compressive forces (or compressive stress) on the beam.Ī lifting beam also features two lugs on the underside that attach to the load. The answer lies in the way their lugs are oriented, and the type of load (or stress) applied to the beams from the load.Ī spreader beam typically features two lugs on top of the beam (one at each end) that attach to the crane’s hook and two additional lugs on the underside that attach to the load. ![]() This question creates confusion among riggers, primarily because spreader beams and lifting beams have similar designs. Spreader beams vs lifting beams: What's the difference? Spreader beams help support uneven or oddly shaped loads for hoisting. ![]() But as simple as a spreader beam’s function might appear to be, there are several things that riggers and engineers must understand when specifying spreader beams for a particular application.įigure 1.
