So one of the prepper groups I belong to on Facebook has been posting these. I thought I’d pass some along. I believe these are meant for law enforcement, hence the “pursuit” comment.
As a prepper, I would not be worried about some of the things LEOs would be concerned about. I look at this scenario and the only “weight” that I would bother to attempt pulling up a steep embankment is a living person. The vehicle and the dead can stay at the bottom of the ravine, if we’re in a SHTF event.
Pulleys make lifting things easier. There’s a system called a 4-in-1 that would work in this case, though we’d be doing a 3-in-1 as we only have 4 pulleys. Rather than spend 20 minutes typing it up, I’m going to share a video that shows you the details clearly.
vehicle down an embankment…
IE- landfill heh heh
So … Drivers name was Philip?
Well, if we’re truly in a SHTF scenario, then we might also be wanting to salvage things from the vehicle. Tires and wheels, and fuel if the tank was intact, come to mind.
Setting up a pulley system for the mechanical advantage is not that hard, and calculating what the mathematical advantage is only slightly harder.
.
But if you have 100ft of rope and 4 pulleys for a 3:1 system, hopefully the inclined distance is less than 25ft (IOW, the vehicle is less than ~21.5ft down), because that’s all the rope you have, and it doesn’t account for knot-tying.
.
It would help to know what the “weight” we’re trying to extract is, along with how many able-bodied helpers we have with us and how much setup time we have. A 4:1 or 3:1 might be overkill — especially if you have a greater distance, more people to help haul, or emergent hazard — in which case a system with less mechanical advantage but allowing for more distance and quicker setup might be more ideal. For example: If we’re trying to rescue a small child (less than 50 lbs), a single-pulley 2:1 setup might be sufficient, or maybe no pulleys at all. Rescuing a 200-plus-lb adult would need a more complex pulley system … unless you have 4 other people with you. And “immobile but stable” injuries can probably take their time, but “life-threatening injuries” (or imminent fire or other hazards) need to be hauled out ASAP even if the pulley setup is less than ideal.
.
But that’s just me overthinking the possibilities. OTOH, context matters, and limiting myself to one “right way” to do things seems like poor preparation.
