Well its the first info I have seen on MND's detachable product
http://www.mnd-group...rayables_FR.pdf
Thanks to our french counterparts for finding the info

Interesting to note the grip uses a linkage that moves the springs to unload them, so it is both a two position grip and should have low opening forces.

The fact that one guy can open the grip makes me a bit nervous. What happens if something jolts the grip on line? On the plus side it'll go through the terminal much easier.
The guy was opening it with one hand with what appeared to be little effort by the end of the video, perhaps this is a demo model with much weaker mechanisms for the purpose of easily showing how it opens and closes...

in the video it looked as if the springs did not move. maybe the springs were not tensioned

The design loads the springs only when a rope is in the jaws, the BMF/Wopfner grip that has been in service for some time has the same feature in that it too can be manipulated when it is not on the rope. When this grip is online it will still require a substantial amount of force to open so inadvertent jolts should not be an issue.
Video of a BMF grip in service being hand manipulated at around the 20-30 seconds for compairison.

Think of the mechanics of a vise grip. When the jaw is not loaded, the various pivots are loose. The Wopfner grip is similar. When snapped over center the jaws are locked. It does require a very interesting (and somewhat noisy) grip actuation rail-almost a tunnel!
Having said that, the MND grip looks quite different in the video at the tradeshow above. It does not look like the grip was actually moved over center by the person operating it by hand.
