A self-stacking helical conveyor (10) including drum (28) supported for rotation on a vertical axis (30), an endless belt (12) trained about the drum (28) in vertically successive helical tiers, beginning with a bottom tier, and having a width spanning a central load bearing portion (14) and opposite side edge portions (15, 16). The belt (12) includes a plurality of successive conveyor sections (78) interconnected for pivotal and translational movement relative to each other. Each of the conveyor sections (78) includes a pair of spaced upstanding supports (82) secured at the opposite side edge portions (15, 16) of the belt, each of the supports having a top detent formation (88d). A bottom detent formation (92) is provided under each of said upstanding supports (82). A supporting assembly is associated with the drum to support the bottom tier and the others of the helical tiers are supported by engagement of the bottom detent formations (92) with the top detent formations (88d) on the spaced upstanding supports (82) in an adjacent underlying tier of the belt.
