FIELD: machine building.SUBSTANCE: coupling unit (10) comprises rolling surface (16) for a friction roller having the first part (12) and the second part (14) which are detachably connected by elements (20, 40), for example, in the form of a pin and a hook. The said parts are connected to each other around a pivot axis (32, 34) being orthogonal to the rolling surface. The rolling surface is continuous and the connection elements are built-in in it. The coupler comprises cross members (50) linked to each other by the above coupling unit. A friction conveyor comprises rails (62) on which carriages (54) of the cross members and a driving unit (64) for the coupler actuated by rolling of the friction roller (70) on the rolling surfaces, move.EFFECT: improved reliability of friction transportation system with the transported cargos being independent for sure.25 cl, 8 dwg |
