1. A coil-transporting carriage for handling one of a coil and a sleeve on a coiler mandrel, comprising:
a coil saddle vertically displaceable by a first drive unit and having a plurality of bearing rollers, each of the plurality of bearing rollers being axially rotatable about a first horizontal direction for receiving the one of the coil and the sleeve;
retaining arms pivotable about the first horizontal direction by rotary drives for stabilizing the one of the coil and the sleeve, the coil being stabilized when an external diameter of the coil is not greater than a limit diameter, the retaining arms being arranged in pairs in a second horizontal direction oriented perpendicularly to the first horizontal direction and opposing one another on the coil saddle;
a second drive unit for horizontally displacing the coil-transporting carriage;
a control unit for actuating the first drive unit, the second drive unit, and the rotary drives; and
a data interface for communication with a higher-level control unit.
