| 摘要 |
The invention relates to a folding frame (1) which is foldable and or adjustable in height and or displaceable in the longitudinal direction and has adjustable step means (16) and these remain positionally stable when the folding frame (1) is unfolded and if necessary a gas spring (65) coupled with a pressureless switch (64) or quick release means (68) can raise the folding frame (1) at any time. The folding frame (1) optionally has a cover (53) and the step means (16) have rail elements (21), wherein the corresponding folding and displacement of a tender on the folding frame (1) takes place by means of sensors and a controller (18). The folding frame (1) has a rotating folding frame (38) that can be offset and optionally a telescoping gangway (41). |
