The invention relates to a hoisting system of a large heavy-load lifting appliance, which comprises a lifting assembly, the lifting assembly is connected with the lifting appliance, the lifting assembly comprises a first hoisting assembly, a second hoisting assembly and a rope, the first hoisting assembly comprises a first winding drum, a first fixed pulley and a first follower wheel, and the second hoisting assembly comprises a second winding drum. The first fixed pulley and the second fixed pulley are fixedly arranged, the first follower wheel and the second follower wheel are arranged on the lifting appliance, and the rope is sequentially wound on the first winding drum, the first fixed pulley, the first follower wheel, the second follower wheel, the second fixed pulley and the second winding drum. According to the hoisting system of the large-scale heavy-load lifting appliance, the mechanical synchronization performance of the hoisting system is improved, the expansion and contraction quantity difference between the steel wire rope groups is reduced, the synchronous control precision requirement of the hoisting motor end is reduced, and the lifting of the lifting appliance is more reliable and stable.
