When we do inspection to suspended scaffolds/suspended platform on site, because of condition restrictions, we can not accurately determine the tile angle of platform, then we can use the following methods to check.
1. To lift the platform one meter high and mark on wire rope in both ends.
2. To fall one end of platform to the point where the safety lock automatically lock the safety wire rope.
3. To measure the distance from mark point on rope to current location.
4. By means of checking, we can determine if the safety lock can meet the requirement.
5. Same method to check another end of platform.
Level difference (mm) FOR two ends of platform
