The key technologies in design and construction of the superstructure of Runyang Suspension Bridge,such as the erection of catwalks,the main stand hauling system and special lifting equipment for steel girders,are presented.
通过研究,采用了双线往复门架式牵引系统,自主研制了能实现均衡放索的大吨位主牵引卷扬机、被动放索机构等关键机具。
In consideration that the numbers of the wire strands of the Suspension Bridge of Runyang Changjiang River Highway Bridge are great and the strand hauling distance is long, the single-rope, round-trip hauling system is used for erection of the catwalk strands, while the double-rope, round-trip hauling system is used for erection of the main cable wire strands.
针对润扬长江公路大桥悬索桥主缆索股数量多、牵引距离长的特点,采用单线往复式牵引系统架设猫道、双线往复式连续牵引系统架设主缆索股,主要介绍润扬长江公路大桥牵引系统的设计和施工过程。
