tnx
Eric
Effective? Well it works. It can certainly be effectively used as a winch. It can be used up to the WLL of the particular brand of jack (and the other components used in the rigging) which is normally enough for most medium sized vehicles unless they are frame deep in sticky mud or weigh 10 tons and need pulling up a cliff.
Is it safe? Like anything else, yes if used correctly. If used incorrectly or without proper care and consideration for what you are doing then it can be lethal. You're using it as a force multiplier to lift, pull or clamp significant loads. If you don't know what you are doing or don't take care in how you are doing it then it's primarily those loads that will hurt or kill you when the collapsing, toppling or breaking jack or part of the jack (never put any part of your body between the jack frame and the handle) releases them. Same thing is in play for any other type of vehicle recovery. Use a winch and a tree to lift your truck up, get under it to stack rocks and the line or branch snaps, the truck landing on you is what hurts but it wasn't the winches fault or lack of inherent safety.
All of that said, if you try using it as a winch once you will almost certainly gnaw your own leg off and eat it to survive until another vehicle comes along to get you out before you will ever try it again…
What they ARE useful for is as an aid to other types of recovery or repair. Lifting parts of a vehicle to clear things its grounded on like trees and rocks. With the wheel adaptors, lifting wheels to put sand ladders, brush, carpet or some other traction aid under them. Lifting a vehicle out of ruts or back onto firmer ground. Used as a clamp or a spreader in trail repairs for mangled underbody bits. The handle is useful as a pry bar, to add force in removing stubborn bolts or as a stiffener for things like bent track rods, etc. What they are useless for is changing tires on trucks with long travel suspension like LRs.
There are many, many uses for them out there including as a winch, you're just never going to want to use it as one twice….
What is often overlooked is that the hi lift is only as good as the available jacking point. If you don't have good solid points on the vehicle to use it on then it's not much good on its own. The tire kit you have is really good for this as it offers a jacking point at each corner. But to use it effectively you need to be able to jack at the front, rear and sides as well. That means bumpers and sliders that are strong enough to handle the weight of the vehicle and have safe points to use the jack. You may not always want to lift wheels in the air and destablize a vehicle.
