The invention relates to a folding frame (1), which can be folded and/or moved longitudinally and/or the height of which can be adjusted and which has adjustable stepping means (16), wherein the stepping means remain positionally stable when the folding frame (1) is folded down, and wherein if necessary a gas spring (65) coupled to a depressurization switch (64) or emergency release means (68) can raise the folding frame (1) at any time. The folding frame (1) optionally comprises a cover (53), and the stepping means (16) have rail elements (21), wherein the folding frame is folded down and a tender is slid onto the folding frame (1) by means of sensors and a controller (18). The folding frame (1) has a rotating folding frame (39) that can be bent and optionally a telescoping gangway (41). |
