Although the removal and installation of billboards belong to Jian 'an project, there is no quota setting, and the final accounts can only be made according to the actual situation. Advertising on the roof and anti-aircraft guns must be budgeted according to different situations.
Before removing the billboard, carefully check whether there are wires connected on the billboard. If yes, immediately notify the electrical professionals to dismantle it before starting work. Before the billboard is removed, scaffolding should be erected around the central column to facilitate the cutting operation. Before the billboard is removed, lock the three corners of the billboard with three brown ropes.
Manual adjustment will not interfere with billboards and crane poles. For billboards, large advertising boards with a thickness of about 3mm are removed to the ground, and some large billboards are cut off from the bottom of the central column by fire welding. Crane will lift the triangle billboard to the ground. Before lifting the triangle signboard, make sure that the triangle signboard is completely cut off from the central column. Finally, the remaining central column of the billboard is removed.
