FIELD: hoisting gears; submarine antenna hoisting gears. SUBSTANCE: tight hoisting gear has fixed trunk with extensible steps inside it; each step is provided with its own hydraulic drive and cable loop for connecting the antenna with submarine hull. Required position of cable loop is ensured by motion of cargo with tension roller over vertical guides fitted in fixed trunk. EFFECT: increased service life of cable due to avoidance of friction of cable loop against fixed parts of hoisting gear. 2 dwg
