The Bridge Girder Carrier, commonly referred to as the beam trolley or traveling trolley, is a specialized motorized transport unit installed on the launching gantry system. Its primary function is to move precast girders (T-beams, U-beams, I-beams, box girders) along the longitudinal axis of the launching gantry and precisely position them above the bridge piers for erection.
