[0002] When installing the space grid roof, it is directly assembled at high altitude or slid to the designed position after being assembled at high altitude. At this time, the grid needs to be moved by a lifting structure; for example, the patent with application number: CN202121322408.2 discloses an auxiliary lifting device for lifting the grid, including a grid ball node and a lifting component.
