ABSTRACT:
A low profile power drive assembly (10) for conveying articles along a conveyor path includes one cylindrical roller (22) supported on an eccentric shaft (32). A first drive motor (26) and a second drive motor (26') are operatively connected to the roller (22) for synchronously rotating the roller (22). The free state position of the roller (22) is in a lower retracted position. When the first (26) and second (26 ') drive motors apply simultaneous driving torque to the roller (22), the roller (22) rises vertically to a lifted operative position to engage the underside of an article to be conveyed. A clutch (38) is disposed inside the roller (22) for controlling the upwardly normal force applied to the underside of the article being conveyed. The assembly (10) is disposable within a standard rollerway (12) in a conventional aircraft cargo conveyor system.
