この発明は橋桁を橋脚の所定位置に架設する方法に関す

業は非常に危険な作業である。Conventionally, the erection girder method was
The majority of methods involve using two girders to carry the bridge, and one girder to suspend the bridge, but in both cases, after the bridge girder has been erected, It is necessary to move the bridge girder laterally to the installation position.
This lateral movement work is extremely dangerous.

なうのが現状である。Another method is to use the girder as a deck to pull out the bridge girder, and then use two gate-type cranes pre-installed on the bridge piers to erect and install the bridge girder, but in this case, a search is required to install the gate-type cranes. Depending on the location of the site, there are often restrictions on where search anchors can be installed, and the current situation is that many dangerous operations are involved when moving a portal crane.
