Abstract
The present invention relates to drives for an automatic lance-changing devices. In accordance with the present invention, the drive effects the coupling of lances used for supplying media by pressing them against a coupling head which, in turn, is accomplished by draw rods which are operated with the aid of lifting spindle movement transmitting screw thread systems. Each draw rod has associated with it its own reduction gear unit which has an integrated lifting spindle system and on which a load cell is mounted. The primary shafts, in alignment with one another, of the two gear units are connected together by a coupling which compensates for axial, radial and angular displacements.
