A people mover, such as a travelator, moving ramp or escalator, comprising a conveyor (1). The conveyor comprises a frame (6), which comprises a first frame part (7), which is secured to a fixed structure, and a second frame part (8), which is mounted to be movable in relation to the first frame part in its longitudinal direction, said first and second frame parts being arranged one after the other. Transport platforms (11) are secured to a first drive element (9) and a second drive element (10), said drive elements being endless elements. A first tensioning device (16) tensions the first drive element (9) and a second tensioning device (17) tensions the second drive element (10), and each tensioning device acts between the first frame part (7) and the second frame part (8). The conveyor (1) comprises mechanical transmission elements (18) between the first tensioning device (16) and the second tensioning device (17) for keeping the stroke lengths of the first and the second tensioning movements equal.

L'invention concerne un système de transfert de personnes, tel qu'un tapis roulant, une rampe d'accès mobile ou un escalier mécanique, qui comprend un transporteur (1). Le transporteur comprend un bâti (6), qui comporte une première partie de bâti (7) reliée à une structure fixe, et une seconde partie de bâti (8) montée pour être mobile par rapport à la première partie de bâti dans sa direction longitudinale, lesdites première et seconde parties de bâti étant consécutives. Les plates-formes de transport (11) sont reliées à des premier et second éléments d'entraînement (9, 10) sans fin. Un premier dispositif de tension (16) met sous-tension le premier élément d'entraînement (9) et un second dispositif de tension (17) met sous tension le second élément d'entraînement (10), chaque dispositif de tension agissant entre la première partie de bâti (7) et la seconde partie de bâti (8). Par ailleurs, le transporteur (1) comprend des éléments de transmission mécanique (18) entre les premier et second dispositifs de tension (16, 17) qui maintiennent égales les courses des premier et second mouvements de mise sous tension.
