The invention provides a crane main beam and a crane with the same. The main beam of the crane comprises a pair of base plates, a pair of connecting rods, a pair of connecting rods and a pair of connecting rods, the pair of arc-shaped plates are arranged on the two sides of the pair of base plates respectively, the upper end of the arc-shaped plate on each side is correspondingly connected with the side end of the upper base plate, the lower end of the arc-shaped plate on each side is correspondingly connected with the side end of the lower base plate, and the upper end and the lower end of each arc-shaped plate are bent towards the corresponding base plates respectively. A closed cavity extending in the first direction is formed by the pair of base plates and the pair of arc-shaped plates. According to the crane main beam provided by the embodiment of the invention, the structure is simple and firm, the wind resistance coefficient is effectively reduced, and the wind resistance is improved.

    本发明提供一种起重机主梁及具有其的起重机。其中,起重机主梁包括:一对基板,一对所述基板上下平行设置;一对弧形板,一对所述弧形板分别设于一对所述基板的两侧,每侧所述弧形板的上端对应连接上所述基板的侧端,每侧所述弧形板的下端对应连接下所述基板的侧端,所述弧形板的上下两端分别朝向对应的所述基板弯曲,一对所述基板和一对所述弧形板形成有沿第一方向延伸的闭合的腔室。根据本发明实施例的起重机主梁,结构简单牢靠,且有效降低了风阻系数,提高了抗风能力。
