It can be used, but pay attention to the diameter of the rope, it should be the same as the product

Just Step On The Hook With The Cable End While Releasing The Lock And Pull The Unit Towards You Over And Over Until Cable Is Extended How Much You Want. :)

I haven't used mine yet, but there is a release mechanism to the bottom of the unit

Yes, of course

I wouldn’t recommend it, these are only rated at 11,000 lbs. and that’s when the line is doubled and not on a single line pull, which means you only have about 5.5’ of line and the puller, which means what ever you’ve attached the puller to, has to be not more than 7-8’ away from your stuck truck. Also adding multiple connections to extend the reach of the puller is not recommended. Also you need to determine the force required to pull the trucks weight (including items on the back) and friction/force to remove it from the snow bank, this could far exceed the power of the puller.

There is no gear ratio for this. This is a maximum of 0.75T, it is suitable.
