[0002] Bridge building machines are mainly used for long-span bridges. Each large section needs to be divided into many smaller sections and assembled. The bridge building machine lifts the prefabricated sections into place and assembles them in the middle of the span. The bridge building machine is selected according to the lifting weight, span and bridge type. Bridge building machines are mainly used for railway box girder construction.

[0003] Chinese Patent CN218951995U discloses a safety protection device for a bridge-building machine, comprising a fixed cylinder, connecting columns, and a safety net.
