ABSTRACT:
The invention relates to an x-ray apparatus comprising an apparatus base, a tiltable part, a displaceable carriage for x-ray parts running on the tiltable part along guide rails and having a spring weight compensation device having compensating forces adjustable by motor drive depending on the apparatus position, whereby at least one slot-shaped opening is provided on the carriage, one end of a one-armed load lever hinged to the tiltable part being displaceable in the slot-shaped opening. Between its ends, the load lever is pivotably connected to a sleeve seated in gliding fashion on a rod, the sleeve being supported with a spring at the one end of the rod whose other end is hinged to a nut displaceable by means of a motor-actuatable spindle, whereby the threaded spindle is arranged essentially parallel to the guide rails.
