80 m Steel Beam Erection by Float-and-tow and Safety and Stability Control

m steel beam of Jing-Hang Canal Bridge spanning over a main waterway was successfully erected by Floating-and-towing at lower side position, then thrusting, and crosswise moving. Here is the introduction to the main facility such as beam assemblage platform, river dock, lengthwise slipway, floating boat fixation, traction power system, and to the key technology like cantilever-free Float-and-tow, ballast composition of cargo boat, simulating tow test, real Float-and-tow, and safety and stability control.
