  • Patent number: 5180047
    Abstract: The balustrade and decks of an escalator or moving walkway are mounted on a conveyor truss via a plurality of anchor brackets which are welded to the truss at spaced apart locations thereon. Template brackets are secured to each anchor bracket to define the location of the outer deck, the inner top shirt panel, the balustrade clamps, and the return path handrail guides. Skirt jack bolt mounts are mounted on the anchor brackets below the return path of the handrail and are operable to provide for proper positioning of the inner side skirt panels relative to the steps. The handrail can be easily released from its return guides and removed from the interior of the decking by removing the inner top skirt panel. The assembly can be easily erected in the field and readily serviced.
