Abstract
A people mover comprising a plurality of steps or palettes to carry and move people. A transmission chain formed into an endless loop is connected to the steps or palettes via which the steps or palettes are moved. The transmission chain comprises consecutive chain links connected in a hinged manner to each other such that the chain links are bendable in relation to each other in a first direction (I) and in a second direction (II). Two turning elements are provided around which the transmission chain is arranged to pass. The consecutive chain links of the transmission chain bend in relation to each other in the first direction (I) when passing around the respective turning elements. A bending limitation mechanism is arranged to limit bending of the transmission chain occurring in the second direction (II).
