FIELD: hoisting-andconveying machinery. SUBSTANCE: proposed device has frame 2 on which swivel ring with drive is mounted and cross-member 6 connected with lock of flying vehicle by means of like converging at lock. Inner surface of ring has diametrically opposite grooves where ends of cross-member are located for transmission of torque or extending from them; cargo ropes 7 are connected to them. Pulleys are mounted on frame on the outside of ring; they are engageable with inner surface of flexible closed members embracing them; their opposite surface are engageable with outer surface of ring for transmitting the torque and slippage in case of overloading. One or several pulleys are connected with drive. EFFECT: extended functional capabilities; enhanced safety. 2 cl, 3 dwg
