An ammunition elevator device is provided for raising and lowering ammunition. The device includes a housing, a crank assembly, a pawl mechanism, and a transfer linkage. The housing has a chamber flanked by first and second flanges. The assembly includes a crank axle, first and second sprockets mounted to the axle for elevating the ammunition, and a ratchet gear mounted to the axle adjacent to the first flange. The pawl mechanism includes a pawl, a toggle and a pin spreader. The transfer linkage has a rotatable bar pivotably connected to the second flange, a rod that radially shifts relative to the crank axle in response to the sprockets, and a pair of rotatable joints. The ratchet gear connects to the axle adjacent the first flange, wherein the gear cyclically pivots the pawl for raising the toggle.
