Abstract: A cable drive for elevator doors has first and second drive pulleys eccentrically mounted 180.degree. out-of-phase on the same drive motor shaft so that the cable feed rate is greater at the middle, than at the start and end of each drive cycle. Feeder pulleys arranged below the drive pulleys ensure that cable angle of feed to tension pulleys positioned at opposite ends of the door travel remains constant, regardless of rotational position of the drive pulleys. The doors travel along guide tracks provided with downwardly directed flanges, behind which upwardly directed flanges of door sheave assemblies are captured. The sheave assemblies also include downwardly directed flanges that are captured behind upwardly directed rails of the tracks. In a single-slide door or center-opening two door arrangement, each door panel has two sheave assemblies and two facing tracks are provided, the sheave of each assembly riding on a different track.
