The invention relates to a cargo boom and a crane. The cargo boom and the crane are used for enlarging the sectional area of the cargo boom. Wherein the radial section of the cargo boom comprises an upper part and a lower part, and the maximum width of the upper part is larger than that of the lower part. The radial section of the cargo boom is a T-shaped characteristic section with the overall upper width and the overall lower width, the T-shaped characteristic section has larger overall height and width range, the transverse bending modulus and the longitudinal bending modulus are remarkably improved, boundary restriction can be broken through, better performance is achieved, and the bottleneck problem that a crane develops towards a larger scale is solved.

    本公开涉及一种起重臂及起重机,用于扩大起重臂的截面面积。其中,所述起重臂的径向截面包括上部和下部,所述上部的最大宽度大于所述下部的最大宽度。起重臂的径向截面为整体上部宽度大、下部宽度小的T形特征截面,T形特征截面具有更大的整体高度、宽度范围,横向抗弯模量和纵向抗弯模量显著提高,能够突破边界制约,实现更好的性能,缓解起重机向着更加大型化发展的瓶颈问题。
