We just got this at auction... amazingly cheap for what it does... rated at 5K, but will lift more. Has made life easier 10 fold, I am loving this thing combined with 4 big jack stands to get stuff up fairly high.

any one have any experiance with these?

I have seen those before but always wondered how well the work. Can you put on the front and one and back and lift the whole thing or is that to unstable?

We only have one right now so I have not been able to try that. Personally I think it would work great. I have seen truck and equipment shops use for jacks sort of like that to lift busses and tractors by each of 4 wheels up to frightening heights with great success.

I would not trust sole support to the Jack. It has what seems ot be a VERY secure mechanical lock that I *think* would be 100% OK but I am just to big a sissy to go with it.

The jack is VERY stable but I doubt I would leave it on one if I was going to be doing heavy pounding or beating on it. The only problem I have had with it is that if you have the rig in park or the brakes locked and try to go up high it tries to pull the vehicle off the jack as it goes up but it has never once gotten the jack to start tipping.

We had one in high school shop class, worked pretty well. Always used jack stands when going under the vehicle though.

i used oen this past weekend at my friends shop where he works. they do strictly exaust work but we have access to the shop on weekends (owner is really cool) they have one of those "big johns". they use it to support the ass end of small school busses and fleet trucks while they are on a normal vehicle lift while they do exaust work on the truck or bus. its pnuematic, but still lifts a shitload, i thought it was real cool

A friend has a couple of those in his barn. We put a lift kit on there once and used one front and rear and it was nice.

The only thing that could be a hassle would be if you were trying to lift a buggy rather than a full-bodied rig.

I used to use something like that at a tire store after high school. Worrked pretty good at lifting, but not very stable after that.

We have one in my shop and we use the hell out of it over our lifts for a lot of projects. I just used it to lift and hold the back of my 32 foot 5th wheel while I put new axles under it I crawled around under it without any jackstands for safety not the brightest thing I know but it seem very sturdy. It is really light for its size also and quick.

We use ours all the time, very nice for projects, quick rear end swaps, etc. Quite stable, makes up for when the hoists are full.

IT is not recommend to lift bothe nds with one. For the reason someone else said, if the other end of the vehicle is not able to roll, it will pull itself off the jack.
I used to have a few of those around, and i seen how bad they are used in pairs before. One of the guys here tried it, and lucky noone was under it when it came down as the second one raised up and the vehicle pulled off the other one.
I think there was even about a full page disclaimer in the manual stating to not use them in pairs.

We have them at our shop. Left over from the air force. They work alright. I believe they used them for the Hummers even though our entire shop is setup for deuce and a half trucks.

I've got one in my shop, inherited it from a friend who just wanted it out of his garage. Never used one before being given this one. I use it all the time! :D
Best freebie I've gotten in a long time.

Friend of mine owns a tranny shop and thats all he has as far as lifts go He has like 4 \

He will put them under the front and back and leave the truck or car on them untill the trans is removed and reinstalled If placed properly They dont fall off.

We use them at work for lifting semis and trailers. I think they work great. Usually we put jackstands under the load, but sometimes we put them under the arm the supports the load. Oh and I think ours are bigger, like 10,000 lbs or so.

Throughout the post this thing has been referred to as "one of those". Anyone got any mfg names or links so those of us who are unfamiliar with these things can be enlightened?

Mineis a Black hawk, no idea of the tool name.. I would guess pnuematic bumper jack or soemthing like that.

I have been thinking about making "attachments" to help in lifting tube stuff orother oddly shapped vehicles... I am sure it is goign to decrease the capacity but most of the stuff hard to grab with it is very light.

I have always referred to them as "walker jacks" it is the old widespread brand name sort of like calling a circular saw a skil saw.

Heres mine (the freebie), its a Hein-Werner. 3K pound capacity.

We use one of those at my uncle's tire shop. Except it is hella bigger. it has dual tanks and if i remember correctly i think it was made by napa. We use it to pick up the rear of semis while putting on tires. It works just fine when i have used it

Latest HF catalog has a 2ton version for 350 bucks item # 33795-5TXA

Get one like shown in jeepin Doud's post and this is not a problem..Jack can move with the load...lov'em

and I thout you were talking 'bout this:

2 4x4's, overkill, I think one would have worked well and he would have had more room under the truck :smokin:

Makes sense to me that you could lift both ends fairly safely if you lifted them both at the same time. Of course you would have to have really long arms or a helper. So are some of these hydraulic and some pneumatic? Tell me what you think about puting a DA cylinder on it so that it can clamp too? Let me know if you think your model would work and what model it is. It would have a few uses.

dude, your gears are missing! :eek: :laughing:

I used to work on theses http://ari-hetra.com/product.cfm?ProdCatID=1&StartRow=1

I've seen them lift some seriously heavy stuff :D

I really like those lifts with one exception...

I once watched a friend using one in High School shop to change his oil and as he rolled under the car to place the jack stands, he also rolled the car right off the lift and crushed his head. :eek:

He lived - but looks completely different than he used to look. It broke his forhead bone, his eyebrow ridges, his upper cheek bones, his nose, and his jaw. It was NOT a pretty sight... :shaking:

The problem with a lot of vehicles is that as you lift, the vehicle rotates around the lifting points and depending on how and where it is lifting, you have to make sure that it still has a firm anchor on the lifting point.

With proper care, they can be a real shop savior, especially for home shops without regular lifts - thus their value - just be careful...

so to cure this maybe a safety chain type setup?

we use 2 of em in a buddies shop when we do odds and end jobs, just wondering if i should be more concerned than i am

wes

As I see it, the main issue comes from the jacking points and the design of the pads that make contact with that point.

Some of the pics on the thread show a flat pad, which may or may not be best - while others have a sort of hook. I would love to have one of those jacks in my own shop (or lack of one...) but I would also certainly make a couple of modifications to the jacking pads to make sure that what I stick on there stays stuck.

The idea of safety chains is a good one - but the problem is that most bumpers arn't open anymore, unless you have a pure rock crawler style tube bumper. I'm not sure where you could actually hook the chains to gain any advantage...

Works great.
Lift the back up and place jack stands under the rear axle. Then lift the front up. It locks solid. Use it to pull my tranny. Here is the best shot I have of it.
