Can you clarify? The gri gri will only let 6 kn through it before it will let some through? Won't bring you to a complete stop? Won't brake your back?
He is essentially saying that the GriGri will slip if excessively loaded. The GriGri's braking power is not infinite, it has a limit. The specifics of this can be found in the GriGri manual. However, simply saying that the GriGri will slip once the load hits 6 kN is very misleading. The tests Petzl published in the manual are just simple tests on seemingly random fall samples. However in actuality, how much force it take to get the GriGri to slip is extremely situation dependent. There are many variables that go into determining how much force the GriGri can actually resist, the biggest probably being rope diameter. So the information outlined in the GriGri manual is just a guide, its not an absolute statement of how much force the GriGri can resist before slipping.
