Patent Number: 6,293,415

Title: Railborne mobile crane

Abstract: A railborne mobile crane mounted on a chassis with a superstructure, a counterweight and a boom which are arranged so as to be swivelable about a vertical axis of the superstructure. The superstructure is contoured so as to be within a prescribed clearance gauge of a section of track. The superstructure is outfitted with a device to compensate for superelevations of curved track sections. Longitudinal sides and a rear side of the superstructure are arranged so that, in every swiveling position, all contours of the superstructure lie within a defined safety area. The safety area is bounded on each of two sides of a longitudinal axis of the crane by an inclined plane which is inclined inward from the vertical, proceeding from a lower edge of the superstructure, by an angle of inclination at least corresponding to a maximum allowable angle of superelevation of the track.
