Kinetic rope snapping

Made nice a job the rear window!

I thought that was the point of a kinetic rope. You take a run up and build up kinetic energy, which the rope stores up as spring energy, then (in theory) converts back into kinetic to pull out the stuck car. Otherwise don't you just use a towrope?

Yes and no, If you put too much load through the system some thing has to break and if its not the stuck vehiclke breaking free then it has to be somthing else like the rope or a chassis.
The correct method IIRC is to take up the slack in the rope and then back up about a meter of 2 at most and then drive forwards so the rope is at about 20% longer than its origional length, at this point you stop. If this is not enough then you should try something else like winching or digging.
Devon-Rover:
I always had thought that with a KERR it was the vehicle to move away at a brisk pace (the heavier the tow motor the slower as momentum is greater / the lighter then the faster.) and then when the rope is at full streach it should exert enough force to pull the stuck motor out.
Should the vehicle be majorly stuck then wouldn't repeated light pulls be better than a few Mahoosive ones which are going to exert a force on the limit of the rope and the recovery points. So then it's time to get winching.

Yours Confused.

thats the worst piece of recovery ive evrt seen :?
even a complete idiot can see that was going to end badly.
if that rope had hit someone it would of killed them instantly.
for [!Expletive Deleted!] sake people, think about the forces your are exerting on your equipment, and if your struggling, stop, take a step back and think of a better way of doing it.
i watched a bloke do that with a steel wire, trying to recover a paj, it did the same, nearly tore thro the bonnet of his truck when it came back at him.
