A double-drum linkage winding type hoisting system includes a first hoisting drum and a second hoisting drum. The first hoisting drum and the second hoisting drum are engaged and linked through engagement structures on outer circumferences of the first hoisting drum and the second hoisting drum or are linked through a linkage intermediate member. A first hoisting rope is wound around the first hoisting drum. A second hoisting rope is wound around the second hoisting drum. The first hoisting rope and the second hoisting rope are not connected with each other.
