Demag; a world leader in overyhead crane design is changing the way we look at load handling. The innovative composition of "V" shaped supports through the interior create an organic tensile strength, much like the interior structure of bone. This design utilizes material only where it's needed, leading to a reduced weight of the overall girder by up to 17%. This reduction in weight also lessens the load on the existing support structure, which allows for higher capacity lifting.
