Abstract
The present invention relates to a structural frame of a crane, lifting device, material handler or a similar machine, comprising at least one elongate structural-frame strut. The invention also relates to such a machine comprising such a structural frame. According to a first aspect, it is proposed not to weld or screw a separate doubled panel or separate retaining lugs to the structural-frame element as a reinforcement, but rather to provide the structural-frame strut with integrally formed, seam-free reinforcement layers in the required, highly loaded region, in order to achieve an organically produced increase in wall thickness and/or cross section in a smooth and harmonious manner. These reinforcement layers are produced using 3D printing.
