ABSTRACT:
A trolley conveyor system chain for pulling trays of the conveyor through horizontal turns and climbing and descending grades. A link of the chain has a single pair of vertical and a single pair of horizontal wheels mounted thereon. A Y or vertical axis of the vertical wheels and an X or horizontal axis of the horizontal wheels intersect at a point and a link mechanism maintains the horizontal wheels in an ideal position relative to a chain rail assembly on which the wheels rotate and also aligns the chain to prevent collapse of the chain under tensile and compressive forces.
