The invention discloses a novel tower crane balance arm pull rod structure. The novel tower crane balance arm pull rod structure comprises an individual pull rod group (11) and a triangular transition structure (1), wherein the triangular transition structure (1) is mainly formed by connecting a cross beam (2) and two symmetrical bending plates (3); two ends of the cross beam (2) are respectively connected with suspending points at two sides of a balance arm; the connection part of the two bending plates (3) is connected with one end of the pull rod group (11), and the other end of the pull rod group (11) is connected with the top of a tower. The novel tower crane balance arm pull rod structure is used for enabling a dual-pull-rod-group structure to be transformed into a single-pull-rod-group structure by means of the triangular transition structure, so that the adaptability and the tolerance property of the novel tower crane balance arm pull rod structure are improved; the phenomenon of unequal length of the two pull rod groups caused by accumulative errors such as relevant component manufacturing is prevented; the assembling efficiency of the novel tower crane balance arm pull rod structure is improved greatly; the manual cost is lowered.
