The invention provides a suspender assembly, a lifting appliance structure and a girder erection crane, and relates to the technical field of bridge construction. The suspender assembly comprises a suspender and a first cushion block, wherein the upper end of the suspender is suitable for being connected with a balance beam, and the lower end of the suspender is suitable for penetrating through agirder erection hole of a box girder; the first cushion block sleeves the lower end of the suspender, a gap is reserved between the first cushion block and the side wall of the lower end of the suspender, the upper end face of the first cushion block is suitable for making contact with the box girder, and a first spherical cambered surface structure is arranged on the lower end face of the first cushion block; and the lower end of the suspender is suitable for being attached to the first spherical cambered surface structure in the vertical direction. When the box girder inclines or slides, theupper end face of the first cushion block makes contact with the box girder, the first cushion block inclines or slides along with the box girder, the lower end face of the first cushion block is provided with the first spherical cambered surface structure, the lower end of the suspender is suitable for being attached to the first spherical cambered surface structure and can rotate to the corresponding balance position along with the change of the state of the box girder, and therefore load acting on the suspender can be reduced, and the suspender is prevented from being damaged.

    本发明提供了一种吊杆组件、吊具结构及架梁吊机,涉及桥梁施工技术领域,其吊杆组件,包括吊杆和第一垫块,吊杆的上端适于与均衡梁连接,吊杆的下端适于穿过箱梁的吊梁孔;第一垫块套设在吊杆的下端,并与吊杆的下端侧壁之间留有间隙,第一垫块的上端面适于与箱梁接触,第一垫块的下端面设有第一球弧面结构;于竖直方向上,吊杆的下端适于与第一球弧面结构贴合。本发明中当箱梁倾斜或滑移时,第一垫块的上端面与箱梁接触,第一垫块随箱梁一起倾斜或滑移,第一垫块的下端面设有第一球弧面结构,吊杆的下端适于与第一球弧面结构贴合,能够随箱梁状态的变化,转动到相应的平衡位置,由此,可以减小作用在吊杆上的载荷,防止吊杆受损。
