This T-shaped bridge needs to be demoulded from the prefabrication plant and transported to the construction site. Due to the large size and weight of the T-shaped beam, it is necessary to use a large platform crane to load the T-shaped beam onto a large flatbed transport vehicle during the transportation process, and then use the large flatbed transport vehicle to transport the T-shaped beam from the prefabrication plant to the construction site.
