The invention relates to the technical field of port equipment, in particular to a drag chain system for a crossing type shore crane. The system at least comprises an external trolley drag chain system (5), wherein the external trolley drag chain system (5) is arranged on the outer side of a shore crane girder (1), and the external trolley drag chain system (5) is further connected with an external trolley (3). When the external trolley (3) moves along the track on the outer side of the shore crane girder (1), the external trolley drag chain system (5) moves along with the external trolley (3), power supply and communication transmission are conducted on the external trolley (3), and the problems that festoon cables are abraded, entangled, pulled out and the like in the related technology are solved.
本说明书涉及港口设备技术领域,具体涉及一种用于穿越式岸桥的拖链系统。该系统至少包括一个外置小车拖链系统(5),所述外置小车拖链系统(5)设于岸桥大梁(1)的外侧,所述外置小车拖链系统(5)还与外置小车(3)连接。在外置小车(3)沿着岸桥大梁(1)外侧轨道移动的时候,外置小车拖链系统(5)跟随外置小车(3)移动,为外置小车(3)供电及通信传输,避免了相关技术中采用拖令电缆磨损、纠缠、拉脱等问题。
