The protective safety ropes are divided into multiple groups from top to bottom and passed through the protective vertical poles and fixed. Planks are laid on the multiple groups of support cross bars to form a maintenance platform.

[0004] The support frames and support cross bars are used to support the floor planks to form a maintenance platform. The support cross bars are fixed to the support frames through mounting frames.
