How to hang anti fall devices on sloping roofs

Because working on sloping roofs, both people and equipment are very prone to high-altitude falling accidents. But where should the speed difference automatic control be hung on a sloping roof like this?

Eaves and pointed roofs are not suitable as suspension points. According to regulations, when using fall arresters for tilting operations, the inclination should not exceed 30 degrees.

Since there is no suitable lifting point on the house, we can only choose another method. Currently, fixing the fixture on the roof and hanging the upper hook of the anti fall device on the fixture is more convenient and quick, and the degree of damage to the roof is relatively small. After use, it can be dismantled in a timely manner.
