In addition, it takes a lot of time to climb to the top beam of the bridge-building machine, which leads to low efficiency of installation and dismantling work.

[0032] Based on this, the present application provides a movable and lightweight working platform for a bridge-building machine. The working platform can be transferred and moved on the bridge-building machine, and the movement is relatively flexible. The various operating platforms set up provide the operators with a good and stable working place and a stable working environment, thereby effectively reducing safety hazards and avoiding the occurrence of safety accidents.
