The invention provides a crane main beam applied outdoors and inconvenient to generate water accumulation. The crane main beam applied outdoors and inconvenient to generate water accumulation comprises a U-shaped bottom beam and an n-shaped top beam arranged inside the U-shaped bottom beam, wherein a Chinese character "gong" shaped bent steel plate is arranged in the space defined by the n-shapedtop beam and the U-shaped bottom beam, horizontal convex ridges are arranged on the upper side and the lower side of the bent steel plate correspondingly, the two sides of each convex ridge are inclined planes, and leaking holes are formed in the positions, corresponding to the two sides of each convex ridge on the upper side of the bent steel plate, of the n-shaped top beam. The crane girder applied outdoors and inconvenient to generate the water accumulation has the beneficial effects that the overall strength is high, the weight is light, the accumulated water is prevented from appearing ona walking board, and dangers are avoided.
本发明提供了一种应用于室外且不易积水的起重机主梁,该应用于室外且不易积水的起重机主梁包括:U形底梁,以及设置在所述U形底梁内部的n形顶梁;其中,所述n形顶梁与所述U形底梁之间围成的空间内设置有呈弓字形的折弯钢板,所述折弯钢板上下两侧分别具有水平的凸脊,所述凸脊的两侧均为倾斜面,所述n形顶梁上对应所述折弯钢板上侧凸脊的两侧位置处均设置有漏孔。本发明的有益效果是:整体强度高,质量轻,放置走台出现积水,避免发生危险。
