Just been reading the 10 rules but cannot scroll down to no10, I can only get to no9, anyone know what no10 say's?.

 

here you go mate...

 

 

 

 

1. Determination of the bracing requirements in case of concretely visible danger.

 

 

 

2. Avoid overdimensioning which would cause increased stress due to a system that is too rigid.

 

 

 

3. Install dynamic breaking-bracing at at least 2/3 of the stem height and as horizontally as possible.

 

 

 

4. In case of long bracing distances of 8 m or more, don't install a shock absorber.

 

 

 

5. Install dynamic crown bracing systems without tension and slack during the summer. In the winter, the connection shall slightly slack so as to avoid permanent load in the summer.

 

 

 

6. Install static breaking-bracing at at least 2/3 of the stem height and as horizontally as possible. Decide in every individual case whether the bracing shall be combined with a dynamic system and/or installed at 2 levels. In such case, the lower level is installed at 1/3 of the stem height.

 

 

 

7. Install static load/support-bracing as vertically as possible and without shock absorber.

 

 

 

8. Never connect stems facing in the same direction with one another.

 

 

 

9. Only one load direction per slinging-around.

 

 

 

10. Any abrasion, cutting-in and slipping must be permanently avoided.
