A hoist mechanism is activated to elevate a trolley hanger from a lowered position to a predetermined position adjacent and above a conveyor rail after which the hanger is stabilized and the rail-engaging wheel of the trolley hanger is positioned in vertical alignment with the rail. The rail engaging wheel is then landed on the rail, the stabilizing force is removed and the hoist mechanism descends to a lowered position.
