The invention discloses a tower crane main cable fixing device and a using method thereof, and belongs to the technical field of tower cranes. The tower crane main cable fixing device comprises a wirepressing fastening assembly and a U-shaped bending bolt. The wire pressing fastening assembly is formed by splicing a fastener I and a fastener II, a wire pressing groove I is formed in the fastenerI, a wire pressing groove II is formed in the fastener II, and the wire pressing groove I and the wire pressing groove II are in butt joint to form a butt joint through hole; positioning through holesare formed in the fastener I and the fastener II, one end of the U-shaped bent bolt is a straight rod threaded end, the straight rod threaded end penetrates through the positioning through holes andis fastened through a nut, and an adjustable fastening space is reserved among the U-shaped bent end of the other end of the U-shaped bent bolt, the U-shaped bent end and the wire pressing fastening assembly. The problems that the cable is not firmly fixed and is easy to fall off and break are solved, the impact force caused by jacking of the tower body is effectively avoided, and the working efficiency and the safety are improved.
