The invention relates to building engineering machines, in particular to a tower crane with a wind-proof structure. A crane boom and a balance arm are rotatably arranged on a rotary table, and a first guyed tower and a second guyed tower are arranged at the top of the top end of the crane boom and the top of the top end of the balance arm. A first cord stretching device and a second cord stretching device are arranged at the tops of the towers. The first guyed tower and the first cord stretching device are connected through a first cord, and the second guyed tower and the second cord stretching device are connected through a second cord. A balance weight lifting device is arranged at the top in a jacking sleeve frame, and can vertically move in standard knots. A balance weight slideway matching the balance weight lifting device is arranged on the balance arm, a first cord lifter and a second cord lifter are arranged on the crane boom and the balance arm respectively, and fixed hooks matching the first cord lifter and the second cord lifter are arranged on a base. A balance weight can be fast mounted and dismounted in typhoon weather or other strong wind states, and after the balance weight is dismounted, the crane boom and the balance arm can be bent to reduce the wind area and keep the gravity center of a tower body stable.
