Transporting girder vehicle is the supporting equipment of bridge girder erection machine. It is mainly used to transport prefabricated beams from girder fabrication yard to bridge erecting site, and cooperate with bridge girder erection machine for bridge erecting operation. It can also be used for the shipment of bridge girder erection machine. Henan HuangHe FangBao Crane Co., Ltd. produces rubber-tyred transporting girder vehicle, which has the characteristics of self-propelled, concrete beam transportation is not limited by distance, complete safety equipment, convenient operation and maintenance, low transfer cost and good stability. It can pass beams directly to the bridge girder erection machine and cooperate with the bridge girder erection machine to span holes. It is more suitable for prefabricated beams and bridging sites which are far away and not suitable for sites with high track laying costs. The company has the ability to design non-standard bridge girder erection machine and transporting girder vehicle. The bridge girder erection machine and transporting girder vehicle designed and manufactured by the company for Hunan No.1 Engineering Co., Ltd. are used for the track laying of sightseeing car in mountain scenic spots. The bridge girder erection machine can work normally under the working environment of 1:10 high slope, sharp bend and long distance, and the requirements for the design and safety performance of the equipment are quite high. The equipment runs smoothly during the gradability test and has good braking performance, which is highly recognized by users.
