1. First, choose a fixed place to tie the rope on the roof platform, and tie the rope several times, so as to be foolproof through repeated load tests. Put rubber or carpet blocks at the bottom of all corners, edges and eaves of the rope to prevent the rope from breaking due to friction.

2. Tie the lifting rope in the U-shaped buckle on the sitting suspension board, and bolt a bucket on the side of the board, which contains half a bucket of cleaning agent. Workers can get on the plate and start work with glass scraper, water wiper and rag. Because there is a special fastening method, the hanging plate will not slide down during work. People can control the rope and operate it freely. Simply speaking, the rope hanger will slide down a little when it is lifted up, which is completely controlled by the construction personnel.
