FIELD: transport.
SUBSTANCE: invention relates to hydro acoustics and can be used as a hydro acoustical hardware hoisting device. The proposed winch comprises winding drum (1) with two side plates (2), separated into two chambers filled with oil (3). Winding drum (1) inside accommodates container (4), tight contactless motor (5) and reduction gear (6) with output shaft. Cable (7) is wound up on the reel between side plates (2) with its two ends running in different directions. Longeron (8) with two hawseholes (9), wherein the cable passes, is fitted on the drum shaft. The motor operates submerged in oil. Container (4) houses control electronic hardware. Output shaft (10) of reduction gear (6) is sealed with the help of packing stuff (11). Bellow (12) equibalances drum pressure with outside pressure.
EFFECT: lower weight, smaller sizes, higher hoisting capacity.
