The invention refers to a transport exchange truck for changing and alternating metallurgic vessels, particularly for steel mill converters. The truck is provided with an interior frame part arranged to rotate in the center of the exterior carriage frame with at least one piston--supportable on the mill floor--of a piston-cylinder unit to raise the exterior frame part carrying the undercarriages. The exterior frame part supports a lift table which can be raised or lowered by means of one or several piston-cylinder units. Each piston rod is connected with the lift table through at least one ball-and-socket joint whose joint housing is provided with articulated traction elements.
