The invention provides a girder based on a tire crane, a girder device and a girder manufacturing method.The girder comprises a top plate, a bottom plate, an inner side web plate, an outer side web plate and two partition plates, the top plate, the bottom plate, the inner side web plate, the outer side web plate and the two partition plates form a box girder structure, and the top plate and the bottom plate are the same in structure and are each of an arc-shaped structure; the inner side web and the outer side web are the same in structure and both bent towards one side. According to the girder disclosed by the embodiment of the invention, the top plate and the bottom plate of the arc-shaped structure are used for avoiding the downwarping phenomenon under the condition of long-term load or overload, and the inner side web and the outer side web are bent outwards in the assembly process, so that the girder web is prevented from being bent inwards under the condition of long-term load or overload; the large beam device not only improves the using effect of the tire crane, but also greatly reduces potential safety hazards in the using process.

    本发明提供一种基于轮胎吊的大梁、大梁装置及大梁制作方法,其中,大梁包括顶板、底板、内侧腹板、外侧腹板和两个隔板,所述顶板、底板、内侧腹板、外侧腹板和两个隔板形成箱梁结构,所述顶板与底板的结构相同且均为弧形结构,所述内侧腹板和外侧腹板的结构相同且均向一侧弯曲。根据本发明实施例的大梁利用弧形结构的顶板与底板避免在长期载荷或超载的情况下发生下挠现象,以及通过在装配过程中实现内侧腹板与外侧腹板的外弯,避免了大梁腹板在长期载荷或超载的情况下发生内弯,该大梁装置不仅提高轮胎吊的使用效果且大大降低了使用过程中存在的安全隐患。
