so i already know i ned to add more bracing in the rear metal bumper support for this modification to have more needed added strength but here is a couple things i have done this past week.
installed factory tow hooks i found in junk yard off ZJ, fabricated front high lift jack mount , and fabricated a rear dual hook system using carriage bolts, plates with clevis's 10k lb chain and 6k lb hooks and hardware. yes its over kill and i love it.

Is that an old bumper jack? I dont think it belongs on your jeep.
 
yes i actually got it off an old grand wagoneer. i plan on getting a high lift xtreme jack when i get a couple bills. but for now i would rather have SOMETHING than be stuck
 
Just don't be anywhere near me or my zj when you decide to use those chains. A classIII reciever with a shackle is all the rear recovery you need, And where the hell would you get Grade 8 carraige bolts, please tell me the bolts holding your recovery points on are at least grade 8. If you have a 6k safe working load hook, a loaded up 5500lb jeep, stuck in the mud, and someone gives it a runnning yank with a snatch strap, do you think it will get less than 6k lb load on it??? Same with the 10k chain. They make recovery chains, and those aren't them.

Edit: I like you're trying to get it done, and save a few dollars, but somethings need money spent to be safe. Like brakes, recovery equip, steering
 
I was just getting ready to ask about the chains but i see someone already beat me to my point.
 
those were the closest chains i could find to the weight limit. as i stated above i need to better support the rear metal bumper support as i want the same pulling cap as a receiver would support. grade 8 carriage bolts from fastenal. and the plates connecting the clevis's are about 3/4" thick. i figure i could pull (after additional support) roughly 4500-5500lbs or rolling weight. i dont know just trying NEW things.

to each their own i guess. i love the set-up !
 
i will have both once i am done and dont plan on pulling anything before i make the additions i need to strengthen the supports.

I PREFER TO HEAR ANY INSIGHT INTO HOW TO BETTER DESIGN THE SYSTEM THAN TO HEAR NEGATIVE FEEDBACK. HELP ME IF YOU KNOW A BETTER WAY.

The better way is to have a good tow strap, not chains. Just ask Chuckman about taking a piece of flying steel to the head. I'm not bashing, I just want you and anyone that may be near you to be safe.

Someone told you in post #4 and you said "to each his own" and that you "love the setup." You got feedback on how to improve it and you basically turned your back.
Let me break it down for you:
Step 1: remove the chains.
Step 2: Read post #4 again.
 
is there anyway to make the chain set-up work safetly ? i mean heavy equipment and tow trucks use chains in that sense they must be somewhat safe to use.
 
Chains can be brutal when they fail. A buddy in Alaska ended up with a broke arm and a plate in his skull from a chain that was being used to snatch someone out of muskeg ( nasty mudhole). 15K strap for $25, awful cheap price for a safer way to do the job. Hook to the shackle and you have fewer points for possible failure. The chain setup pictured has failure points at every non-factory connection. Just trying to keep someone from getting hurt.
 
Yes they do but they are using them on known static loads not jerking flash point loads. Those used by the above mentioned are also alloy load rated chains that don't come from home improvement stores.
 
I'll also add that we use chains for hoisting all kinds of stuff and each are tagged with capacities= over 1000/2500$ investment.:rolleyes:
 
^x2
towtrucks use chains to secure load once in place and hooks on end of cable to winch. Different forces are into play when doing a snatch verses a constant pull of winch.
 
okay . so im guessing you know how to weld per your name on here . if i redesign a heavy duty grade steel rear bumper with high grade chains would that make it safer/stronger ?

i dont plan on snatching anything with these mainly for added security when pulling a rolling payload .

maybe switching to heavy duty cable in place of the chains ???????? thoughts ?
 
Are you planning to tow with the chains or do a recovery of someone stuck. It sounds by your last post that the chains are for towing on the street.
 
A strap will still be cheaper, it can still pull rolling loads and you can jerk on it. A strap will also give you a bungee affect and will lesson the shock applied at either end. You can run one with very little changes, just buy a larger clevis to put it through. Mine is on a reciever dedicated to this purpose. Pop it into the reciever; use, then stow back in the tool box.
 
^X2 beat me to my thought.
 
okay so i know i still need to add additional strength to rear bumper support but if i changed out the chains to two straps could i still use the hard ware i.e hooks and mounts safely ?
 
If the ZJ is anything like my DD XJ there's not alot of anything behind the bumper. The hitch is factory and has a known load rating, I'd use that. You really don't even need a clevis. Just insert the strap into the reciever hole and use the hitch pin to secure it. The chain would make some really good overkill safety chains on a trailer, maybe. And before you argue that its strong enough for that then why not use them on your ZJ: If you ask most people they would rather not run safety chains on a trailer. The DOT requires them so you have to have them. I personal would rather get away from a trailer that has went FUBAR enough to require chains to catch it.:beer:
 
^^ ahha yeah good point. well i thank everyone . got a lot of thinking/ maybe redesigning to do. but i know one thing for sure i want some MORE than just receiver hitch to be used for pulling.

Maybe if we spell it out...

- DO put aside "how cool you think they look" dangling beside the "Punisher" hitch insert and LOSE the chains, totally/completely. The ONLY use for them would be securing the rear of your Jeep to something larger (not long enough for that) when winching (and you have NO winch) a heavier weight rig or something on a steep grade. As already stated, chains are used offroad ONLY to statically bind your rig to something of greater weight or resistance when winching and to bind up broken parts to get off the trail (broken links, leafs, steering boxes, etc.).

- LOSE the hooks, totally/completely. They'd only be good for the single reason you'd need a chain (see above, which you don't). There should be NO hooks on the recovery strap the past 5 folks have suggested. Hooks & clevis's for that matter, become projectiles if/when the strap breaks... think of a medieval "mace" with the ability to cut humans in half.

- BUY 1 (ONE) quality (less than $50) recovery strap. Affix 1 end of it to the front hooks or better yet (suggested 3-4 times before) attached to the rear hitch.

Reinforcing the tin (sheetmetal) the current bumper is screwed to and following the above tips will go along towards function... and might get you/others extracted from a stuck, as opposed to dead.

Please DON'T take this as "negative feedback" :beer:
 
naw all good. and as toolbagish as it makes me , YES i do like the tough look to it. but i do tow a trailer and could be useful for that simply as DOT ruling.

i think im going to leave them there until i figure something out. but not use them

but i understand everyones reasoning . sometimes i see more form than function with my ideas.

but you cannot deny MAD MAX WAS COOL !!! ahha lol
