Pengangkutan Ketepatan untuk Beaders Precast Direka untuk Melancarkan Sistem Gantry

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.

Unit ini memainkan peranan penting dalam memastikan pengendalian yang selamat, stabil dan tepat; daripada balok berat semasa projek pembinaan jambatan menggunakan span-by-span  atau kaedah cantilever seimbang.
