FIELD: mechanical engineering; load-lifting facilities; hand lever winches. ^ SUBSTANCE: according to invention, grips are made with tubular bodies of rectangular section. Four through holes are made in body of each grip. Upper holes are designed for tow segment cams with double-arm guides fitted-in from one side of grip body, and lower ones are designed for segment cams provided with single-arm guides fitted from other side of grip body. Double-arm lever of turn drive is two-section one, both sections of lever being connected by neck to pass wire rope from below. Each section is provided with slot with two axles fitted in cheeks of said slot. Said axles of one of sections are hinge-connected with power tie-rods hinge-connected with paired links of lower arms of double-arm guides of both grips from one of their sides.
