While both a lifting beam and a spreader bar is similar in that they create a connection point between the load and crane there are differences that make one better than the other in specific instances.
If we resolve the forces on the whole beam we get the force diagram as above.
Lifting beams are more appropriate for lifting large unstable objects and can be used where low headroom is an issue.
It is a simple design with one lifting eye on the beam s topside for connecting the crane.
At the outset it is important to clarify the difference between a spreader and a lifting beam.
