Ratchet Switch under load

Our team is trying to use a ratchet to release stretched surgical tubing (like I imagine a lot of teams are doing). We pull back our shooter using a winch and then shift into neutral so our motor shaft is no longer connected to the winch shaft. As the winch tries to unwind the ratchet holds it in place (ratchet acts as a hard stop).

The problem that we have however, is that nothing we have tried has been able to flip the ratchet's directional switch while it is under load. I have seen a couple other teams using this idea and so I am a bit confused as how they released the surgical tubing.

So to you other teams we are successfully releasing surgical tubing, how are you doing it under load?
