An apparatus for conveying bulk material generally consisting of a support and a guide means defining a passageway. The passageway has a vertical section and a horizontal section cantilevered to the vertical section. A endless rope assembly passes around the passageway. Disc are displaced along the rope to catch and transfer bulk material along the passageway. The bulk material is injected into the passageway at the lower end of the vertical section and is ejected at the end of the horizontal section. A motor drives sprockets located at the ends of the passageway and at the cantilevered portion. Such guide means may consist of a single passageway or a pair of passageways of differing lengths, and such support may be movable on wheels.
