<p>The combination has a coupling (1) for rotatably movable connection with a drive. A height holding device (3) is integrated into the combination, and comprises disks for friction-fit connection. The coupling, a brake (2) and the height holding device comprise actuating systems, and the actuating systems comprise a piston (12) and a spring (15). The actuating systems are hydraulically controlled, and are hydraulically connected together. A safety valve is provided for controlling the combination, and a pin (22) is attached to pistons of the actuating systems for anti-twist protection.</p> |
