  • People mover, transmission chain and method in the use of a people mover
    Patent number: 8312978
    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.

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.
