When the installation of lighting roof is finished,the main stel beam is lengthened and increasing the counterweight,then the operation platform is demolished with the hoisters and pulley scaffolds. The construction platform has lots of advantages, including low construction investment,low installation cost,high safety of working at high altitude,and the inner decoration is not influenced when the lighting roof constructs.
