The invention provides a girder lifting device. The girder lifting device comprises a walking mechanism, a stand column, an upper cross beam, a lower cross beam and a lifting assembly. Wherein the lower cross beam is installed on the walking mechanism, the stand columns are installed on the lower cross beam and comprise the first stand column and the second stand column which are arranged in a spaced mode and the third stand column and the fourth stand column which are arranged in a spaced mode, and each of the first stand column, the second stand column, the third stand column and the fourth stand column comprises multiple sections of column bodies which are detachably connected; the upper cross beam is detachably connected with the first stand column, the second stand column, the third stand column and the fourth stand column; the lifting assembly is used for driving the girder to conduct lifting motion. According to the lifting device, the upper part structure of the lifting device is disassembled before base shipping so as to meet the requirement for height limitation of a bridge in the transportation process, the bridge is installed after reaching a destination, girder lifting operation is conducted through the installed lifting device, and the lifting device is simple in structure, convenient to install and high in practicability. And the girder lifting operation depending on large equipment is avoided.
本发明提供一种大梁提升装置,该提升装置包括行走机构、立柱、上横梁、下横梁和提升组件。其中,下横梁安装于行走机构上,立柱安装于下横梁上,立柱包括间隔设置的第一立柱与第二立柱,以及间隔设置的第三立柱与第四立柱,第一立柱、第二立柱、第三立柱以及第四立柱均包括多段可拆卸连接的柱体;上横梁与第一立柱、第二立柱、第三立柱和第四立柱可拆卸连接;提升组件用于驱动大梁进行提升运动。根据本申请的提升装置,在基地发运之前将提升装置的上部分结构拆卸,以满足运输过程中桥梁的高度限制,到达目的地后再进行安装,并利用安装好的提升装置进行大梁提升操作,该提升装置结构简单便于安装,避免依赖大型设备对大梁进行提升操作。
