The invention discloses a reverse disassembling method for a tower crane. Under the condition that the tower crane cannot be normally disassembled, a guide wheel is arranged at the position, 3 m away from a tower body, of a balance arm of the tower crane, a two-rope lifting hook is arranged through the guide wheel, and a hoisting mechanism is formed. A hoisting rope is guided out of the hoisting mechanism through a main winch, and the hoisting rope passes through a hoisting sheave to the guide wheel which is arranged on a small special portal at the position, 3 m away from the tower body, of the balance arm. The hoisting rope is connected with a movable pulley in series after passing through the guide wheel. The end of the hoisting rope is anchored on a cross beam of the small special portal at the position, 3 m away from the tower body, of the balance arm. Disassembled standard joints are hoisted by the self-assembly hoisting mechanism to the ground, and therefore the aim of tower lowering is achieved.
