Diagnostic X-ray ceiling mounting has setting drive for movement of transverse carriage along ceiling rail selectively disengaged to allow manual movement

摘要

The mounting has a setting drive for movement of a suspended transverse carriage (2) along a ceiling rail (1) for providing layer X-ray images, employing an electric stepping motor (4) with a drive cog (6) mounted on the motor axis (5), selectively coupled to a rack (10) along the rail via a coupling cog (8) mounted on a pivoted wiper.
