Abstract

Die Erfindung geht aus von einem räumlichen Schutzgitter für Axiallüfter, dessen radiale Tragstreben zur Erzielung der räumlichen Gestalt des Schutzgitters mehrfach abgewinkelt sind und zur Gewährleistung einer hohen Biegesteifigkeit aus gebogenen Flachprofilen bestehen, sowie einem Verfahren zur Herstellung eines solchen Schutzgitters.

Figure imgaf001
The invention is based on a spatial protective grid for axial fans whose radial supporting struts are angled several times to achieve the spatial shape of the protective grid and consist of curved flat profiles to ensure a high bending stiffness, and a method for producing such a protective grid.
