The invention discloses a hoisting and balancing device. Three vertical bars are arranged at the three vertexes of a triangle respectively, a sliding part sleeves the outer part of each vertical bar, can vertically move along each vertical bar and is provided with a connecting rod, one end of each connecting rod is articulated to the side, facing the center of the triangle, of the corresponding sliding part, and the other end of each connecting rod is articulated to a fixed part. According to the hoisting and balancing device disclosed by the invention, drive equipment is not needed, and with the arrangement of the three vertical bars which are distributed in a triangular shape, the weight in the hoisting or falling process can be limited in the horizontal direction, so that the phenomenon that weight swings in the hoisting and falling process, therefore, the tension applied to a cable rope is strengthened, and the bearing capability of a boom is also strengthened, so that potential safety hazard are caused, is avoided.
