Extendible fences for extendible conveyors are disclosed. An example conveyor includes a fence assembly having a plurality of channel segments including at least a base channel segment, an intermediate channel segment, and a distal channel segment. The fence assembly is adjustable in a lengthwise direction such that the fence assembly is longer in the lengthwise direction when a main conveyor assembly is in a fully extended configuration than when the main conveyor assembly is in a fully retracted configuration. The intermediate channel segment is interposed between the base channel segment and the distal channel segment with respect to the lengthwise direction. Each channel segment of the plurality of channel segments includes sidewalls extending upward from a bottom panel. The intermediate channel segment to move in translation in the lengthwise direction relative to an intermediate conveyor section. The bottom panel of the intermediate channel segment is positioned between an upper portion of a conveyor belt of the main conveyor assembly and an upper load bearing surface of the intermediate conveyor section. The upper portion of the conveyor belt being interposed between the sidewalls with reference to a lateral direction, where the lateral direction is horizontal and perpendicular to the lengthwise direction.
