I am thinking about hill climbing safety . . . .

Is there a device that can be used in conjunction with rope that would allow a Grizzly to make progress up a steep hill BUT limit or prevent the Grizzly from falling or moving backwards.

I’m thinking that it would require the driver to tighten up slack as he/she made forward progress.
