Dangerous hydraulic jack

Recommended Posts

I just realised I have had one of these cheap jacks for 25+ years. It  works alright but is not so stable laterally if the floor is not flat. The only real problem with it is it doesn't stay up. I always use stands so that is not a problem. I also always put a block of wood on the top cup (I use 100 x 50) to reduce the chance of steel on steel slip.

 

Its rating is 2 tonne, but I don't think it is good for much more than a tonne. Jacking that much requires a bit of force on the handle.

My 2 cents for my fellow Canadians. I purchased a 3 ton Motomaster floor jack from Canadian tire on sale a couple years ago and couldn't be happier. It's a low profile quick pump, lifts effortlessly and fast! No complaints and I don't know why I waited so long to get one.

I avoid buying anything from China if I can help it. I absolutely refuse to buy any hydraulic implement from there. Since I couldn't find a new US made jack, I bought a used one. It's big and ugly but it works great. It's maybe 40 years old and shows no signs of leaks. I just have no idea what brand it is. I paid less than I would have paid for a new Chinese one with a 1/4 of the capacity.

I had a  Sears 2 1/2 ton. The first time I used it on a smooth and level concrete floor it  tipped.

Something had bent and 1 wheel was up in the air with no load on it.

Lifting the rear of 1967 wagon with a set of golf clubs in the back use to much weight for it.

Since we're talking about jacks and jack stand safety... if you are buying jacks stands these days you might want to re-weld them.   Almost all brands/models are two pieces of stamped steel joined with, get this... a spot welded butt joint.   That shouldn't even be a thing (and I likely just made up that term).  If you look at your stands you'll see what I mean.   I had a set of 3 tons holding my modern sedan up and I took a break for the night.  Being the paranoid type that I am, I had another set of jack stands positioned next to the jack stands but at a slightly lower level (obviously you can't get them tight up against the frame).  When I went under the car that morning I noticed that the secondary set of jack stands was now tight against the frame.   One of the other jack stands had split right at that spot welded butt joint.  I've attached a picture and circled the area I'm talking about... the joint runs all the way up the stand under the sticker... same for the other side.   Mine had 4 spot welds.  I threw them in the garbage, bought 5 ton jack stands,  took the stickers off (the one that warns against modifying the jack stand) and had them re-welded with a true continuous butt weld.

Makes me glad I usually use wood jack stands! Dad made me the first set 35 years ago. I need to make some more.:)

 

They are made like one builds a floor in a typical platform built house. 1 x 4 (or whatever you have) about 15" long, enough to be 12"+ wide (act as the "ceiling sheetrock), 2 x 4 as the floor joists, at least three, the more the merrier, and then more 1 x 4s for the "floor".  For taller ones, you can use 2 x 6 as the "floor" joists. For best safety, also nail a "rim board" across both ends, cutting a hand hole so you can pick them up and carry them. Most of my 2 x 4 ones do not have the ends (rim board) and some have half height "rim boards".  Stack three or four high if needed! Cars do not slide off of them. 

 

And on a similar note, we needed to hold up a heavy "Buffalo" like vehicle and we built jack stands out of  3/4" plywood. About a foot and a half wide and 4 feet long sheets glued and screwed together to a height of one to two feet. Talk about a heavy jack stand! Almost took a forklift to move them. We also made ramps by cutting progressively shorter plywood pieces, glued and screwed. Yes, we used brand name 50 ton hydraulic rams to actually lift the truck.;)

The other thing with jack stands such as those above is the lateral stability is sometimes poor because the ratcheted shaft is much narrower than the slot it runs in. You can rock the car sideways - a bit frightening if you are under there.

My first choice is a quality used product every time if I can find it. My Walker jack was built about 1967. For the ecologist that is great. Most of the carbon byproducts of manufacture and shipping were incinerated during atmospheric nuclear tests in the 1970's.

 

How will the affects of a new one be neutralized?

Whenever  I am working under a car, I always place it on jack stands, of course. I also have an additional jack stand that I keep near me, so in case the car falls, the additional jack stand will prevent the car from crushing me. As I move around, I move the jack stand with me. I'd rather be safe than sorry. As a retired Firefighter, I have responded to calls of people trapped under cars. Sometimes it's not pretty.

I'm with 46 woodie.....chinese, american or where ever the manufacturer is from, I just can't come to grips with trusting anything man made or mechanical. That's just me.

I look at it this way - ifyou use good tools and good parts you generly come out ahead and will be safe under or driving the car.  Use junk in either case and you will pay for it eventually. Think about what you are doing and be safe. Simple bottom line that usually works.

You wouldn't buy a cheap diamond for your wife why buy a cheap tool for yourself. They are one in the same in a lot of ways. Both work towards your well being.

Have fun

You might as well. You can't trust visual inspections anymore.

What about the brakes in your "modern heap"? This would lead to great paranoia whenever you were in a vehicle.

OK guys I get it....flying, driving, walking, shaving, I meant more on being under 2 tons of metal, by myself trusting only minimal support. I don't use 2 floor jacks but 4. Less odds of failing or getting crushed. If all 4 fail then my bad.

Interesting comparison. Were you alone or sitting with a bunch of guys having coffee when you thought that?

I've seen enough floor jacks fail to not rely on them to hold stuff up without some other mechanism that takes over when one fails. Usually they slowly leak, but I have had them (even brand names) just pop a seal and drop the load. No telling what my employees had been using it for before I used it.....:huh: What rating, just keep pumping till something moves....:o

 

Now where can I get in on a cheap diamond? Which of the four Cs do I go low to get it cheap? But honey, everyone is wearing brown diamonds this year!:D

I told my Wife to look close. The diamond was intricately carved to a replica of a mosquito knee join. She knows I put quality before quantity.

Did you buy miniature tools or a compact car?  Big diamonds can be quality diamonds. I’ll ask your wife how she liked the new diamond she got for her birthday that you posted a picture of on the forum.  I can come up with a pic. 

Now that that’s solved back to original subject.

My '56 Cadillac weights 5,800 pounds...no way I'm sticking my head under there without jackstands, and chocks on the tires.:unsure:

Wow.  So now a thread complaining about a "dangerous" jack (that was not used properly) and that then morphed into a b*tchfest about Harbor Freight (which wasn't even the source of the original jack) has again morphed into a thread about using jacks without jackstands???  Wow..... :blink:

 

For the record, getting under a car supported only by a jack (any jack) without stands is evolution in action. Why does this even need to be mentioned?

Me son is a nuclear operator up here. One of the fellows where he works came to the cafeteria for a coffee and forgot to turn off his Geiger counter from when he last used it. It went off when he came to the table taking a reading. Everyone checked themselves thinking someone was hot but they were all ok.  Found the chairs were made in China from recycled material that should never have been used. True story.
