The invention provides a winch support and belongs to the technical field of machinery. The winch support solves the problem that an existing winch support is not stably connected with a truck body and the connecting strength is not high. The winch support comprises a left side plate and a right side plate which are in piece shapes and are the same in shape and size. The left side plate and the right side plate are opposite to each other. The lower end of the left side plate and the lower end of the right side plate are provided with connecting holes which are opposite and are for a belt shaft to penetrate, a fixed plate is connected between the upper end of the left side plate and the upper end of the right side plate, the two sides of the fixed plate are fixed with the left side plate and the right side plate through welding, and a sealing plate is connected between the middle of the left side plate and the middle of the right side plate. The two sides of the sealing plate are fixed with the left side plate and the right side plate through welding, the fixed plate is perpendicular to the plane where the sealing plate is located, and the surface of the fixed plate and the surface of the sealing plate are provided with mounting holes. The winch support has the advantages of being connected with the truck body stably and being high in connecting strength.
