[0003] Patent publication number CN113928975A discloses a heavy-duty lifting device with a monorail trolley, comprising a monorail, with a lifting beam group A and a lifting beam group B slidably connected below the monorail. The lifting beam groups A and B are connected via connecting rods and connectors. Each of the lifting beam groups A and B comprises a main crossbeam and a load-bearing beam, which are connected via connecting rods and connectors. The upper end surfaces of both ends of the main crossbeam and the load-bearing beam are connected to trolley connecting beams, and both ends of the trolley connecting beams are connected to lifting trolleys. The top end of each lifting trolley is slidably connected to the outer surface of the monorail. The present invention improves lifting efficiency and distance while effectively reducing transportation costs and is safe and reliable.
