A method transfers unit loads to storage channels for storage by conveying the unit loads to the storage channels using a unit load receiving device movable along the storage channels in an x-direction and a transporter extendable into the storage channel in a z-direction. The transporter includes outer transport elements in opposite end sections and optionally an in-between inner transport element. The unit load is moved from the unit load receiving device into the storage channel up to an intermediate position using one transport element by moving the transporter in a first direction. The transporter is then moved to a second direction to position the other transport element behind a unit load side wall facing the unit load receiving device. The unit load is finally shifted in the storage channel from the intermediate to the second depth position using the other transport element by moving the transporter.
