FIELD: transport engineering; pull winches. ^ SUBSTANCE: device for fastening wire rope 1 on drum has slot 3 of width not less than diameter of wire rope made in form of groove on outer surface of drum. Wire rope 1 is fitted in slot. Device is provided also with fasteners in form of colts 5 fitted in holes. Slot is trapezium-shaped, with widening towards outer surface of drum and depth more than one but less than two diameters of wire rope. Holes for fasteners are made on outer surface of drum along slot to act by bolt heads onto wire rope. Thread of bolts is either right-hand or left-hand, depending on direction of winding-on wire rope. Cylindrical guide 6 for taking up cross forces can be made on bolts 5. ^ EFFECT: simplified design, provision of reliable fastening of wire rope, reduced metal usage. ^ 2 cl, 3 dwg |
