The invention provides a quay crane crossbeam, comprising: a crossbeam body comprising an upper truss and a lower truss, a mounting space being formed between the upper truss and the lower truss; the drag chain support is arranged in the installation space and fixed to the upper truss, and the drag chain support is arranged in the length direction of the girder body and used for supporting a drag chain so that the drag chain can be located in the installation space. According to the quay crane girder, the drag chain support is arranged in the installation space of the side, facing the lower truss, of the upper truss, so that the overall height of a quay crane is effectively reduced, and the height requirement of low-posture container transportation equipment is met.
本发明提供一种岸桥大梁,包括:大梁本体,包括上桁架与下桁架,上桁架与下桁架之间形成有安装空间;拖链支架,拖链支架设置在安装空间内,并固定在上桁架上,拖链支架沿大梁本体长度方向设置,用于支撑拖链,以使拖链位于安装空间内。本发明的岸桥大梁,通过将拖链支架设置在上桁架朝向下桁架的一侧的安装空间内,从而有效降低了岸桥的整体高度,满足了低姿态集装箱运输设备的高度要求。
