An apparatus for lowering particulate commodities includes a vertically disposed ladder extending from the upper end of the storage facility to the lower end of the storage facility. The ladder is formed of flexible planar sheets bent upon themselves to define substantially U-shaped chute member formed into a zigzag pattern such that the particulate commodities flow downward through the chute members passing from one chute member to the next chute member. The chute members are connected such that an opening is formed at the upper end of each chute member so that the commodities may exit the ladder once the level of the commodity within the storage facility has reached the upper end of a particular chute member.
