Falcon 500 + Ratchet Slice ... Which will win?

Just as a heads up for those making winches and climbing, be sure to never run a ratchet slice the wrong way against a Falcon 500. See here the aftermath.

Yes, that is a bent bolt. Ripped the bolt out of the front shaft housing of the gearbox and tore up the ring gear housing just behind.

For reference this was a 35:1 reduction from the Falcon 500.

Luckily we had another ratchet slice as this one was wrecked.

Impressive.

We had a similar failure a few years ago with 2 775pros as the input.

Yup. This is what can happen when you don’t follow load ratings.

From what I see, the ratchet is not the first stage after the motor, prior to any reduction. That is always preferable so that there is the least force possible on the ratchet, and is probably the root cause of this issue.

We’ve done similar things with encoder placement - and versa slice encoder placed on the output of a 775 that is running flat did not fare well.

Not trying to derail the thread, but does there happen to be any rating on rpm when using the versa ratchet? In 2018 on our fork winch we had a ratchet slice on the first stage of our 775 reduction (to lower the load on the ratchet) and experienced a lot of broken ratch pawls. We never ended up pursing this failure mode as we found the gearbox was geared high enough to not back drive very much, but maybe you can shine some light on this.

Broken pawls:
