Here are some more details:
1, The main support leg adopts the joint-dominated triangular structure. The supporting wheel train 〖JP3〗mechanism is used on the main support leg. Without any anchor measures, the main support leg is designed to realize the structure self-〖JP〗stabilization and can resist overturning moment which bridge erecting machine over the span to the next pier.
2, With the constant drive mode on the main support leg, the bridge erecting machine realizes the synchronization control mode of different driving methods and improves the safety and reliability in operation.
3, Through alternating functional transformation technique of the main support leg and auxiliary support leg, the bridge erecting machine can over the span to the next pier without the need of the guide beam. The operational process is simplified and the bridge erecting machine can erect box girder at the tunnel entrance and erect box girder inside the tunnel.
