摘要:
A method of constructing an elevated roadway, utilizing a crane having an articulated boom arm and a gripping mechanism, at the end of the arm for gripping a pylon, below a roadway cradle of the pylon, in order to temporarily transfer loads, generated by a tramway moving a precast bridge section along the crane arm and onto a pair of cradles, mounted upon the pylons. The construction method permits the crane to be positioned on an assembled portion of the elevated roadway, while constructing the remaining portion of the elevated roadway.
