![]() ![]() Some bending may be experienced as the forces F1x and F2x are acting at the hole of the pad-eye, which is offset from the centerline of the spreader by some distance. We can see that the vertical downward forces of Fv1 and Fv2 are balanced by the components F1y and F2y, while F1x and F2x are the compressive forces on the spreader. If we resolve the forces on the whole beam, we get the force diagram as above. ![]() A spreader beam is designed to take primarily compressive loads, as can be seen in the figure above. The spreader beam discussed here is one with two lifting points, from which the lifting slings go vertically straight down to the lashing points on the cargo as shown in the figure below:įig 1: Arrangement of a spreader bar Spreader beam vs Lifting beamĪt the outset, it is important to clarify the difference between a spreader and a lifting beam. In this article, we will explore the design of a basic spreader beam and see what design checks are needed to establish the suitability of a spreader beam for particular lifting operation. Spreader beams are universally applied gear which is widely used in various types of lifting operations, onshore and offshore.
