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.

A tension member termination device optimized for terminating flexible flat tension members, the device including a socket with a compression portion and a bulbous portion and a compression plate on each side of the compression plate on each side of the compression portion fastenable by fasteners extending through all of these feature. The device provides a pathway for the tension member through the device and upon torquing the fasteners reliably secures the tension member while avoiding deleterious pressure and stress therein.

A pretensioning system for a relating cable synchronizing movement of elevator car doors includes a compression spring and a spacer disposed on one end of the relating cable. The compression spring is compressed to the length of the spacer disposed internally to the spring to calibrate tension in the relating cable so than a no-slip condition is ensured.
