Rail base of girder erection crane

The utility model relates to the technical field of bridge erection, in particular to a track base of a girder erection crane. The base comprises a top plate, two side plates, at least one connecting plate and two bearing plates arranged at intervals. Wherein the top plate is used for supporting a crane track; the two side plates are arranged on one side of the top plate in parallel at intervals and avoid and are higher than the shear nails; the at least one connecting plate is arranged between the two side plates and is connected with the top plate and the side plates; one side of each bearing plate is connected with the corresponding side plate, is perpendicular to the corresponding side plate and is used for being pressed on the steel beam. The problem that in the prior art, a beam erecting crane is difficult to move on a steel beam provided with shear nails can be solved. 本实用新型涉及桥梁架设技术领域，具体涉及一种架梁吊机轨道底座。该底座包括：顶板、两块侧板、至少一连接板和两块间隔设置的承压板。其中，顶板用于支撑吊机轨道；两块侧板间隔平行设置的设于顶板一侧，且避开并高于剪力钉；至少一连接板设于两块侧板之间，并与顶板和侧板均连接；每块承压
