<p>A device of this type has up to now been arranged outside the steam-generator chamber (1) so that long conveying distances have to be covered. To achieve trouble-free exchange of tools or inspection probes, the support (10) has a swivel cylinder (15) detachably connected to the device. An output shaft of the swivel cylinder carries a feed device (16) for axially moving a flexible shaft (13), and a compressed-air motor (17) for driving the flexible shaft is allocated to the housing of the swivel cylinder.
