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.

Abstract: The invention relates to a monitoring and control system for mobile lifting and transport devices such as cranes, building machines, and transport vehicles, in which status data is obtained by monitoring selected device components and conveyed to at least one control console. Data and/or control commands are transmitted from the control console to the monitoring and control system. The system is operated with an open expandable architecture of exchangeable standard PC components and uses a real-time operating system for hard real-time computing and with a user program which conforms to IEC 1131-3.
