Abstract
An x-ray examination apparatus has a base with at least one fixed part and one carriage that can be vertically shifted in relation to the fixed part. The carriage is provided with a horizontally projecting shaft, to which an apparatus component is mounted and which has a center axis around which the apparatus component can rotate. A pulley with a peripheral surface that is at least partially round is rotationally mounted to the shaft and is firmly connected to the apparatus component. A first pair of wheels is arranged at the fixed part of the base and a connector is provided to connect the pulley to the wheels so that whenever the wheels are respectively simultaneously rotated in different directions, the pulley and thus the apparatus component are vertically shifted and whenever the wheels are rotated in the same direction, the pulley and thus the apparatus component are caused to rotate around the center axis.
