There are various types of prefabricated bridges in stations, and the main beam types generally include main line beams and platform beams.

[0003] Nowadays, many construction sites require bridge-erecting machines to frequently turn around and erect concrete beams in both the forward and reverse directions of the construction line. A variety of beam-erecting equipment is needed for construction. The process is cumbersome and time-consuming. In addition, the feeding positions of concrete beams in existing construction scenarios are diverse. At the same time, it cannot meet the requirements of erecting various beam types such as main line beams and platform beams, and meet the requirements of various feeding positions such as front, middle and rear. The scope of application is relatively small. In order to solve the above problems, a new type of bridge-erecting machine is urgently needed to solve the above problems. Utility Model Content
