The invention discloses a double load-bearing trolley of a tower crane. The double load-bearing cart of the tower crane comprises a rear trolley, a front trolley, an auxiliary lifting hook and a main lifting hook; the rear trolley comprises a rear trolley frame, a guide wheel and a pulley block; the front trolley comprises a front trolley frame, a guide wheel and a pulley block; the rear trolley and the front trolley run on a cargo boom rail through the guide wheel and is fixed or separated through a trolley connecting shaft; the auxiliary lifting hook is connected with the pulley block of the rear trolley through a wire rope; the main lifting hook is connected with the pulley block of the front trolley through a wire rope; the auxiliary lifting hook and the main lifting hook are fixed or separated through a lifting hook connecting plate. The load-bearing trolley is designed to double trolleys, the two trolleys are connected with each other, the double trolley is used when four-times lifting weight is used, the overall width of the double trolley is relatively large, and the intertwining phenomenon of the wire rope can be effectively avoided. A single trolley is used when the two-times lifting weight is used, the other trolley is fixed on the root of the cargo boom, the overall weight of the load-bearing trolley is reduced, and the lifting performance of the entire machine can be greatly improved.
