ABSTRACT:
A portable x-ray diagnostics apparatus has a radiation receiver mounted at one end of a height-adjustable column by a support mount. The lower, opposite end of the column is attached to a wheeled base of the apparatus. A height-adjustment mechanism is provided inside the column and the base which permits the height of the x-radiator above the base to be adjusted without an electromotive drive, and such that the force exerted for adjusting the height of the column is substantially the same over the entire adjustment path. For this purpose, one end of a cable is connected at a location inside the lower end of the column, and the cable is guided around various deflection elements, with the opposite end being attached in the base of the apparatus. A weight compensating force is provided by a spring connected to one of the deflection elements, with the spring being horizontally tensed in the base of the apparatus.
