ABSTRACT:
The moving handrail on an escalator or moving walkway is first tightened on its guide rail to the extent necessary to eliminate substantially all handrail slack in the handrail loop. Thereafter, the handrail is loosened so as to impart optimum slack thereto whereby handrail friction and heat is minimized during operation of the escalator or moving walkway.
