<p>From each foot (11) on the consoles (10) extends upwards an element (14), the upper part of which connects to a rail tube (20). A roof operator connects his life line to an axially slotted slide fixture (60) which permanently encompasses the rail tube (20) along which it is displaceable past the consoles by virtue of its slot. The element (14) is pref. deformable under the effect of a load corresp. to that applied to the consoles via the ridge rail tube (20), and the forces transferred to it via a life line in the event of an accident.</p> |
