A few days ago, the 1,000-ton concave girder vehicle was independently developed and produced by Qinhuangdao Tianye Tonglian Heavy Industry Technology Co., Ltd, and will be delivered to Shangrao City, Jiangxi Province in mid-January for the construction of the Changjinghuang Railway Project.
The 1,000-ton concave girder vehicle.
The 1,000-ton concave girder vehicle is mainly composed of the vehicle body, wheels and steering devices, girder trolley, power system, hydraulic system, electrical system and braking system. The vehicle is 60 meters long, 8.8 meters wide, with 31 axes and 248 tires, being designed and manufactured according to the construction characteristics and requirements of the double-track combined box girder of the passenger railway in China.
It is suitable for the concrete box girder of 1,000 tons and 40 meters, which can transport the concrete box girder from the prefabricated site to the girder erecting site through the sidewalk, railway subgrade, or bridge, and complete the girder erecting operation with the bridge erecting machine.
Yang Guilong, design supervisor of Qinhuangdao Tianye Tonglian Heavy Industry Technology Co., Ltd., said, “We spent 6 months to develop and produce this girder vehicle. The most challenging part is how to transport the girder to pass the tunnel with a proper height.” The concave structure of the girder vehicle is unique to others, which tackled the challenge mentioned above, and applied the patent to practice.

The vehicle is a high-tech product that combines “machinery-electrics-hydraulics”, leveling with hydraulic drive, hydraulic suspension, connecting rod steering and hydraulic lifting. The vehicle runs flexibly. It can not only move in a pigeon-toe way, but also realize no-slip or less-slip driving, finishing works on a smaller site. “This girder vehicle can be operated by the driver or remotely controlled in any conditions.” Yang Guilong said.
Qinhuangdao Tianye Tonglian Heavy Industry Technology Co., Ltd. is a major high-end equipment manufacturer, integrating R&D, design, manufacturing, installation, and sales services, producing bridge equipment, lifting equipment, special vehicles, and TBM (tunnel boring machine) for national key projects such as transportation, energy, logistics, and aerospace, being exported to more than 40 countries around the world.
