Abstract
A movably mounted pillar-stand for carrying X-ray equipment, the pillar-stand preferably celling-suspended and having a pendulum arrangement or the like for the purpose of damping natural oscillatory movements. When natural oscillatory movements occur in the pillar-stand when making positional adjustment thereto, the natural oscillatory movement of the stand is effectively extinguished within the space of some few seconds by a damped, counter-directional pendulating movement imparted to the pendulating arrangement by means of the natural oscillatory motion of the stand.
