The DF900D railway fixed launching gantry is used for the erection of 900-ton box girders in the construction of high-speed railway. It can be carried by the girder transporter to realize transition between bridges. This equipment uses guide beam to assist girder feeding and adopts fixed-point lifting. Girder erection is completed by the span support structure.

With simple structure as well as high safety and reliable, the girder erection equipment can meet the requirements of short-distance girder erection in the entrance and exit of tunnel. Till 2011, we had manufactured nearly 30 sets of DF900D railway fixed launching gantry. These products were widely used in the construction of domestic high-speed railways.
