A conveyor for the transport of bulk materials contains three pairs of supporting cables located vertically one above another. A conveyor belt is movable along the supporting cables and at its ends guided over return drums. Fastened to the conveyor belt are supporting beams having ends mounting rollers, which roll along the middle and lower supporting cables. Supporting frames are located at a distance apart in the longitudinal direction of the conveyor and by which the supporting cables are mutually connected. The supporting frames are formed by two vertically aligned supporting struts and two horizontally aligned connecting struts and, the upper ends of the supporting struts are connected to one of the upper supporting cables. The connecting struts are connected by clamping devices located thereon to the middle and to the lower supporting cables. The clamping devices located on the connecting struts form an acute angle with the connecting struts.
