The invention discloses a crane main beam and a crane. The crane main beam comprises an upper panel and side plates located below the upper panel, the upper panel is a horizontal straight plate extending in the longitudinal direction, the cross section of the crane main beam is defined by the upper panel and the side plates, the side plates form arc-shaped edges on the cross section of the crane main beam, or the cross section of the crane main beam is a convex polygon formed by the side plates and the upper panel, and the number of edges of the convex polygon is 9 or more. According to the crane main beam, the wind power coefficient of the main beam on the crane can be effectively reduced, the capacity of bearing large wind power is improved, the safety of the main beam structure under the storm working condition is met, and meanwhile the manufacturing cost of the whole crane and a wharf can be reduced.

    本发明公开了一种起重机主梁以及起重机,其中起重机主梁包括上面板和位于上面板下方的侧板,上面板为沿纵向延伸的水平直板,起重机主梁的横截面由上面板和侧板包围形成,其中,侧板在起重机主梁的横截面上形成弧形边,或者,起重机主梁的横截面由侧板与上面板形成凸多边形,凸多边形的边数为9或者更多。本发明的起重机主梁,能够有效降低起重机上主梁的风力系数,增大承受较大风力的能力,满足暴风工况中主梁结构的安全性,同时也能降低整个起重机以及码头的制作成本。
