Abstract: An inserter assembly for inserting containers onto a storage carousel. The containers may be inserted by moving them horizontally in a direction tangent to a curved portion of the storage carousel. The container is then latched into the rack by raising a vertically movable horizontal lifting member to lift the lower outside edge of the container and tilt the container toward the carousel to engage a latching mechanism on the rack. The latching mechanism includes leading and trailing hooks with a smooth and continuous bottom surface, with the leading hook having an inclined wing sufficiently wide to rest on the upper leading inside corner of the container until it hangs over the inside of the container.
