预制梁的精密运输——专为启动龙门架系统而设计

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.

该部门在确保安全、稳定和准确的处理方面发挥着至关重要的作用；在桥梁建设项目中使用逐跨的重型梁；或平衡悬臂法。
