CRANE, IN PARTICULAR OVERHEAD CRANE OR GANTRY CRANE, COMPRISING AT LEAST ONE CRANE GIRDER

摘要

The invention relates to a crane, in particular an overhead crane or gantry crane, having at least one crane girder that extends horizontally in a longitudinal direction. The crane is designed as a trussed girder and comprises struts which connect an upper run and a lower run together. The upper run and lower run of the trussed girder are designed in a laminar manner, on which a crane trolley having a lifting gear can be moved. The at least one crane girder is advantageously improved by virtue of the fact that the struts are designed in a laminar manner, each strut has a main surface that extends transversely with respect to the longitudinal direction of the crane girder. The first or second strut end of each strut has at least one aperture on the main surface that lies against the lower run or the upper run.
