![]() The compression stress with which spreader beams deal requires less material to resist than the bending stress seen in lifting beams. In comparison to lifting beams, a spreader beam, or a combination of spreaders, is generally the most cost-effective solution. Spreader beams are designed to deal with compression, not bending, therefore, it is crucial to remember that a spreader beam will likely fail when misused, as it is 3 to 4 times smaller than a lifting beam. Problems occur when a spreader beam is treated as if it were a lifting beam. The most appropriate scenario for lifting beam usage would be in the case where there is limited headroom and/or multiple points of lift. In contrast to lifting beams where the force must travel along the beam before it can continue upwards to the crane hook, in the case of spreader beams, there is no bending stress applied to the beam by the load as there is an immediate path for the force to travel upwards via the top sling. ![]() The main reason to use a spreader beam in any lifting scenario is to remove the compressive forces in a load, which may otherwise be lifted with angled slings alone.
