运梁车(图1)是高速铁路建设不可缺少的运架设备之一,在国产900t运梁车转向方式上大多采用连杆转向方式,而在独立转向控制方式上应用较少,但国外进口高速铁路运架设备已广泛采用独立转向系统,因此,为紧跟世界运架设备发展趋势,国内也开始生产独立转向方式900t运梁车,因900t轮胎式运梁车是一种特殊的车辆, The girder transporter (Figure 1) is one of the most important transport equipment for the construction of high-speed railway. Most of the steering methods of domestic 900t girder use the connecting rod steering mode, while the independent steering control mode is used less, but the foreign imports Therefore, in order to keep pace with the development trend of the global transportation equipment, the country also started to produce the 900t independent beam turning vehicle. Because the 900t tire beam moving vehicle is a special type of vehicle,
