Abstract
The invention brings forward a hanging beam of a bridge crane. The hanging beam comprises a main beam body, multiple lower lifting lugs and multiple upper lifting lugs. The main beam body has a prolate shape. The multiple lower lifting lugs bulge downward out over the bottom of the main beam body. The multiple lower lifting lugs are arranged along the length direction of the main beam body from one end to the other end. The multiple upper lifting lugs bulge upwards out over the top of the main beam body. The multiple upper lifting lugs are arranged along the length direction of the main beam body from one end to the other end so as to fit with the bridge crane with multiple lifting points. The upper lifting lugs of the hanging beam can be connected with the bridge crane through pins. The lower lifting lugs can be connected with a hoisted object by the use of shackles and steel wire ropes. Thus, large-scale equipment is hoisted at a time, the process of reassembling equipment after disassembling hoisting is removed, secondary damage to equipment is avoided, installation period of equipment is saved, high rental charge of a floating crane is saved, and large-tonnage hoisting requirements are met.
