An elongated sweep apparatus for moving particulate matter in a bin may comprise a sweep assembly movable over the floor of the bin and including a particulate sweep structure configured to move particulate matter toward the inboard end of the elongated sweep apparatus, and a housing generally extending between opposite ends of the sweep apparatus with a portion of the sweep structure being positioned in the housing. A first portion of the particulate sweep structure may extend along a primary movement axis and a second portion of the particulate sweep structure may extend along a secondary movement axis, and the primary movement axis may extend substantially parallel to the floor and the secondary movement axis being inclined upwardly from the primary movement axis.
