The invention discloses a top loading structure of a tower crane, which consists of a tower head, a balance arm and a cargo boom, and is characterized in that a transition connecting frame is arranged below the tower head, and the tower head and the cargo boom respectively consist of a triangular beam, a support rod and a diagonal draw bar which are connected with the triangular beam; the triangular beam is composed of two parallel bottom beams arranged at the bottom and a single top beam arranged at the upper top end, the two ends of the single top beam are respectively provided with a pin shaft sleeve connected between the balance arm and the cargo boom or between the segmented cargo booms, and parallel connecting rods are arranged between the ends of the two parallel bottom beams and within the spacing distance between the ends of the two parallel bottom beams. Tower head buckle sleeves are arranged at the connecting ends of the two parallel bottom beams of the tower head and the balance arm, and four tower head clamping pin seats connected with the transition connecting frame are arranged on the two parallel bottom beams of the tower head at the connecting ends of the adjacent tower head supporting rods located at the middle section of the triangular beam. The device has the advantages of being convenient to transport and install, low in cost, good in stress structure and safe.
