Bridge Girder Carrier (Traveling Trolley / Beam Trolley for Launching Gantry)
Precision Transport for Precast Girders – Designed for Launching Gantry Systems
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.
This unit plays a critical role in ensuring safe, stable, and accurate handling of heavy beams during bridge construction projects using the span-by-span or balanced cantilever method.
