The endless belt and steps are guided about a loop which includes load bearing and return runs for the steps, by guide wheels rotatably mounted on a common side of the endless belt, and a guide track. The guide wheels and guide track cooperatively define the first and second yieldable guide points, and first and second non-yieldable guide points, which function at different levels of side thrust forces on the endless belt.</p> |
