The invention discloses a gantry crane device for steel truss girder construction, and belongs to the technical field of building construction. The gantry crane device for steel truss girder construction comprises a cross beam, frame bodies are arranged at the two ends of the cross beam, a movable base is fixedly arranged at the bottom of each frame body, and the gantry crane device further comprises a movable beam, a movable beam and a movable beam, and the movable beam is arranged on the lower side of the cross beam and is perpendicular to the cross beam; the transverse moving assembly is arranged in the cross beam and used for driving the movable beam to move transversely; the lifting appliance is movably arranged on the lower side of the movable beam; the longitudinal assembly is arranged in the movable beam and is used for driving the lifting appliance to move longitudinally; wherein a gravity offset assembly is arranged in the movable seat; the longitudinal working range of the lifting appliance can be increased without overall displacement of the large-size gantry crane, the structure is simple, operation is convenient, the bridge building construction efficiency is improved, and when the lifting appliance lifts materials longitudinally, the stability of the structures on the two sides of the gantry crane is guaranteed, shaking of the lifted materials is avoided, and the overall stability of device operation is enhanced.

    本发明公开了一种钢桁梁施工用龙门吊装置,属于建筑施工技术领域。一种钢桁梁施工用龙门吊装置,包括横梁,横梁的两端均设置有架体,每个架体的底部固设有移动座,还包括:活动梁,活动梁设置在横梁下侧且与横梁垂直设置;横移组件,横移组件设置在横梁内,用于驱动活动梁横向移动;吊具,吊具活动设置在活动梁的下侧;以及纵向组件,纵向组件设置在活动梁内且用于驱动吊具纵向移动;其中,移动座内设置有重力偏移组件;本发明无需对体积较大的龙门吊整体位移,即可增加吊具的纵向工作范围,结构简单,操作方便,提高桥梁建筑施工效率,且在吊具对物料纵向起吊时,保证龙门吊两侧结构的稳定性,避免起吊的物料晃动,加强装置运行的整体稳定性。
