SUBSTANCE: overhead belt conveyor has support frame with closed guide secured at both sides of conveyor and made in form of single pipes, and endless conveyor belt passing over drive and end drums to which uniformly spaced roller hangers are secured for moving along guides bent in space. Guides on load carrying section are moved to each other to increased depth of groove formed by belt, and in area of drums they are moved apart to provide adjoining of belt to working surface of drums. Each pair of roller hangers located in one plane square to longitudinal axis of conveyor is interconnected by means of two flexible plates to which conveyor belt is fastened. Parameters of flexible plates are determined by relationship Bt≥P•Kvar•Ks/i•σst where Bt is width of flexible plate, mm; P is flexible plate extension force, N; Kvar is flexible plate loading variation factor; Ks is flexible plate breaking safety factor; σst is breaking strength of one layer of flexible plate, N/mm; I is number of layers in tape from which flexible plate is made. EFFECT: improved reliability of conveyor operation. 4 cl, 6 dwg
