Abstract
The assembly/dismantling of the axles and/or the steps or pallets of escalators or moving sidewalks is accomplished by providing between the parallel-extending traction elements a plurality of axles. The axles have flattened zones in the assembly region for the steps or pallets. Eyelet-shaped assembly regions for the steps or pallets have corresponding slots which are fitted onto the axles. The axles are turned at a predetermined angle around their longitudinal axis, relative to the steps or pallets, and at least one connecting element is inserted for securing the axles in the assembly region relative to the steps or pallets.
