Crossing protection facilities are required to protect them during the construction period. It involves a wide range of areas and has high reliability and safety requirements. The currently used crossing frames include scaffolding-type crossing frames, bridge-type crossing frames, cableway-type crossing frames and other types.

[0003] In the related art, the existing crossing frames can only be fixedly installed, with poor flexibility, low adaptability to complex line conditions, and relatively complicated installation and disassembly. In addition, operators are unable to inspect and maintain the lines above the crossing frames. To this end, we propose a truck crane crossing platform that can safely carry line maintenance personnel.
