However, since the goods carried by the hoisting frame may be irregular in shape, or when the goods are placed on the frame base, the goods may not be in the middle position of the base, which will cause uneven mass distribution on the left and right sides of the frame, so that the center of gravity is not at the midpoint position. The rigging on the existing hoisting frame is usually fixedly connected at the end corner position and cannot be adjusted. Therefore, during the process of hoisting the frame, the center of gravity of the frame and the goods may deviate, which will cause the frame to tilt or the goods to fall, thereby affecting the efficiency of hoisting transportation. Therefore, we propose a hoisting frame convenient to adjust hoisting gravity center to solve the above problems. CONTENT OF THE UTILITY MODEL
