  • the advantage achieved in this way is that due to the selected distances between the first guide units and the second guide units from one another, there is double guidance and/or support of the ladder element on each ladder side after a predetermined adjustment path.

Abstract

L'invention concerne un ensemble échelle extensible (8) et un véhicule d'urgence ou de sauvetage (1) équipé de celui-ci. L'ensemble échelle (8) comprend une pluralité de parties échelle (19 à 13) et un agencement de guidage (33) pour au moins la première partie échelle supérieure (9). La partie échelle supérieure (9) comprend un élément échelle (17) et un bras pivotant (18) qui sont reliés l'un à l'autre de manière articulée au moyen d'un agencement pivotant (19), dans lequel, à partir d'un axe d'articulation (27), des rails latéraux (28) de l'élément échelle (17) font saillie d'une longueur (42) au-delà de l'axe d'articulation (27) dans la direction d'une tête d'échelle (15). L'agencement de guidage (33) comprend des première et seconde unités de guidage mutuellement opposées (34, 35) qui sont espacées d'une distance (38) dans l'étendue longitudinale de l'échelle. Les distances (38) entre les première et seconde unités de guidage (34, 35) correspondent chacune au plus à une longueur (42) selon laquelle les rails latéraux (28) de l'élément d'échelle (17) font saillie au-delà de l'axe d'articulation (27).
