FIELD: mechanical engineering; rope winches. ^ SUBSTANCE: proposed winch has drive drum with first and second ropes installed on frame and connected with drive by tooth clutch. Drum consists of two separate sections installed with clearance between end faces. First section is rigidly connected with shaft, and second section is installed for rotation on shaft and locking. Second section of drum consists of two parts being arranged between said bearing support and first section of drum. Diameter of first part of second section is equal to diameter of first section of drum. Clearance between end faces of sections is made to pass ropes from one section to the other and free rotation of second section relative to first section of drum without contact of section end faces. One end of first rope is secured on first section of drum. One end of second rope is secured on second part of second section of said drum. ^ EFFECT: enlarged functional capabilities of winch. ^ 3 cl, 10 dwg |
