FIELD: transport.SUBSTANCE: invention relates to load-carrying structure of winch. Load-carrying structure of winch includes two side supports and not less than two longitudinal stiffening elements entering by their ends the mentioned side supports and holding these supports in a spaced position. Ends of longitudinal stiffening elements are fixed in side supports, and one of side supports has through holes to provide possibility of dismantling these stiffening elements. In operative position of lifting mechanism the ends of longitudinal stiffening elements are detachably fixed in side supports, and one of two side supports is made so that longitudinal stiffening elements can be inserted or removed through one of side supports during assembling, dismantling or modification of load-carrying structure. Therefor, the first side support has through holes for longitudinal stiffening elements.EFFECT: simplified winch design.20 cl, 4 dwg |
