A track-and-trolley conveyor guidance system for collecting and moving material into or away from a selected bin (30a, 30b, 30c) that resides within an array of storage bins. The conveying system comprises three or more trolleys (90, 91, 92, 93, 94, 95a, 95b, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108) that move along at least one track (79, 80, 81, 82, 83, 84, 86a, 86b, 86c, 86d, 86e, 86f, 87a, 87b, 88a, 88b, 89) to create a guide assembly for a conveyor (60). By moving the trolleys (90, 91, 92, 93, 94, 95a, 95b, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108) along the track (79, 80, 81, 82, 83, 84, 86a, 86b, 86c, 86d, 86e, 86f, 87a, 87b, 88a, 88b, 89), or track (79, 80, 81, 82, 83, 84, 86a, 86b, 86c, 86d, 86e, 86f, 87a, 87b, 88a, 88b, 89) along the trolleys (90, 91, 92, 93, 94, 95a, 95b, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108), the conveyor (60) or conveyor groups (67, 68, 69, 70) can distribute material to or reclaim material from a selected storage bin (30a, 30b, 30c) using minimal amount of linear meters of conveyance (60). The conveyor guidance system can have multiple layers of guide assemblies (110, 112, 114, 120, 122, 124, 126, 128, 130, 132, 134, 136, 138, 140, 142, 144, 146, 148, 150, 152, 154, 156, 158, 160, 162) to guide conveyor (60) or conveyor groups (67, 68, 69, 70). The conveyor guidance system can have the guide assemblies combined in a wide variety of configurations that best suits a particular application.
