Abstract (en)

[origin: EP0878431A1] The escalator (1) has at least one torsional-resistant backbone (9) which is able to absorb the forces engaging at the sides on the moving staircase. The backbone is set in a lower part (8) of the support body (7) or between the forward leading steps (4) and returning plates. The backbone is formed by a closed tube made from thin-walled sheet metal bending parts. The backbone can be provided as a sandwich structure in the lower part inside the support body. The backbone can be foamed or filled with filling material.
