南昆铁路跨线桥桥面板安装受现场地形限制,部分桥面板无法采用现有的技术和设备进行吊装安装,设计了一套适用安全,操作方便高效,易于控制的预制桥面板的安装装置。 The installation of bridge deck of Nankun Railway overpass bridge is limited by the site topography. Some bridge deck can not be installed by existing technology and equipment. A set of prefabricated bridge deck installation device is designed which is safe, convenient, efficient and easy to control.
