Every now and then people ask us about our devices seemingly lower maxium load declaration. Even in the media we can sometimes see weird speculations on this topic. In some comparison tests you can read stuff like:
aeroSling ELITE 120 kg – brand XYZ 500 kg
The big problem with this is that some people start comparing apples with oranges. In Germany and Europe we have very strict regulations.
In order to warrant 120 kg each part has to hold at least 720 kg (security factor 6x). Therefore, if brand XYZ claims 500 kg to be their max load, their device “should” withstand at least 3.000 kg before breaking.
Our max load declaration is further based on the fact that our device can endure the average life-cycle including load peaks without compromise. This has been officially tested from german authorities.
In order to pass the test, the device had to withstand thousands of repetitions with 120kg. Additionally, these repititions have been performed with rotational force on the rope and pulley over the full length of the rope. That way the pulley had to work much more than it would in real life.
Ergo: We build high-quality devices and our breaking loads are much higher than the stated maximum training load. Officially tested!
