Natančni transport za predhodne nosilce – zasnovan za zagon portalnih sistemov

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.

Ta enota igra ključno vlogo pri zagotavljanju varnega, stabilnega in natančnega ravnanja  težkih nosilcev med gradbenimi projekti mostov z uporabo razpona po razponu  ali uravnotežena konzolna metoda.
