The invention discloses a tower crane having a windproof function, and relates to a building machinery. A lifting projection part and a balance projection part, opposite in positions, are arranged on a rotating table; a lifting arm slot is formed in the lifting projection part; a lifting rotating table is arranged in the lifting arm slot; a lifting rotating shaft is arranged on the lifting rotating table; a lifting arm is on the lifting rotating shaft; a balance arm slot is formed in the balance projection part; a balance rotating table slides in the balance arm slot; a balance rotating shaft is arranged on the balance rotating table; a balance arm is on the balance rotating shaft; a stay rope tower A and a stay rope tower B are arranged on the lifting arm and the balance arm; a rope stretching device A and a rope stretching device B are arranged at the tops of the towers; a counterweight lifting device is arranged at the inner top of a jacking sleeve frame, and can vertically move in a standard joint; and a counterweight slide way is arranged on the balance arm. Compared with the prior art, the tower crane can quickly install and disassemble a counterweight block in the coming of typhoon or in other gale states, and can bend the lifting arm and the balance arm to reduce the wind suffering area so as to keep the gravity center of the crane stable after the disassembly of the counterweight block.
