The invention provides a novel tower crane split type cargo boom. The novel tower crane split type cargo boom comprises an upper plate frame, side plate frames and a lower chord member, the two ends of the upper plate frame are fixedly connected with one ends of the two side plate frames correspondingly, and the other ends of the two side plate frames are detachably connected to the lower chord member to form a triangular frame structure. The upper plate frame, the side plate frames and a connecting plate set are respectively machined and welded to form an upper structure, and the upper structure and the lower chord member are machined, produced and transported respectively so that the machining and transportation problems caused by the over-width and overweight of a single piece can be solved, and before a tower crane is mounted, the upper structure and the lower chord member are assembled into a whole.
本发明提出了一种新型塔机分体式起重臂,包括上板架、侧板架和下弦杆,所述上板架两端部分别与两个侧板架一端部固定连接,两个所述侧板架另一端部可拆卸连接于所述下弦杆上,以形成三角框架结构。本发明通过将上板架、侧板架和连接板组分别加工并进行焊接组成上部结构,上部结构和下弦杆分别加工生产和运输,可以避免由于单件超宽、超重而引起的加工和运输难题,塔机安装前,将上部结构与下弦杆组装成整体即可。
