ABSTRACT:
The forks of a conveyor tray are hingedly mounted between two end forks rdly interconnected by a cross-bar and through which electrically powered drive chains impart movement to the tray along a vertical conveyor path. The hingedly mounted tray forks are releasably held in normal load-supporting positions on the cross-bar in alignment with the two end forks, so that they may be pivotally displaced upwardly from such positions by travel resistance forces in excess of a safety level.
