Double Locking Jack Stands

Upon further review of my ratching jack stands I'm looking at these, just don't trust ones without a pin lock...

Mike, did you buy them from this company? They seem like some nice stands. I noticed that they had no pricing that's why I was wondering. If not where did you purchase them at.
 
I've not purchased them --I've seem then online.. The Company makes ones that are not double locking as well (appears Home Depot sells those). I wish I had the set I made as kid in 10th grade welding class.. they held up a F350 without issue but by Brother lost them....
 
I'm kind of crusing around and comparing.

It would seem the HarborFreight items DOES NOT have the double lock feature. It does, however, meet the ANSI/ASME standard for jack stands in that the lock pawl CANNOT be moved with the load/pawl in place due to a shear pin between the handle and the pawl.

It would seem that the Northern Tool item DOES have the double lock feature. It also meets the same standard as the Harbor Freight item - but not more as the ANSI/ASME standard does not address double lock - this merely an addition based on consumer aesthetics/market differentiation. Also about a $10 addition in price.

Likely BOTH stands are made by the same Pacific Rim supplier. There is not much made in the US today. Nice that they are willing to follow US standards - or so they claim.

Being a sort of frugal sort myself, I might go after the cheaper of these since one can't move the handle and knock the load off hook anyway. No sense in giving them any more of our money than we have to.

But your money - also you under the load. We all makes our choices.

Just don't end up like Mark Fydrich.

Single points of failure are not an option with 2,000+ lbs above me.. I own the Harbor Fright stands --not going to use them.... Garage sale items...

I drilled holes and use old cheap screwdrivers (ground the tips) to make them secure. Don't throw them away, modify them.

I was recently looking for some stands too.

I looked all over the place, but they were either nasty cheap looking pieces of crap, or VERY expensive.

10 minutes on my local ebay equivalent (trademe) had me a pair of stands the same as Dads - 60's or earlier, large cast base, threaded shaft with a thick handwheel that screws them up to height.

Absolutely stoked to have gotten them for about US$45 for the pair.

I'm going to keep an eye of for more of them, though I don't know if I'll be that lucky!

Actually, the failure mechanism is the same with either stand. The lock only locks the pawl when the load is off - it has nothing to do with descent of the load should the pawl fail.

Unless as suggested you drill a hole and pin it.

Pity. Were Cow Hampshire closer I could have helped you with disposal of your perceived hazard.

FWIW: Just another type that I bought about (7) years ago when they were $14.00 a pair ...... now they are $19.00 a pair.

The ratchet types usually fail at the single shear area of the cast iron teeth protruding from the cast iron bar because of a poor or defective casting ..... many are cast & made from parts in China.

The two (2) pairs I bought shown below are Canadian made by "Larin", "all" steel, no cast iron, with no possibility of a void in the cantilevered cast iron teeth causing failure.

Anybody familiar with structural steel analysis will be able to immediately see the positive safety factor built into the non-cantilevered all steel Canadian "Larin" Jack Stands.

Larin jack stands are provided with 2, 3, & 4 Ton Models.

Bought these jack stands from FLEET FARM, Oshkosh, WI.

Now, if one likes to take chances, just buy four (4), of the cheaper three (3) legged jack stands from e-bay to use when tightening large bolts under your Model A ..... might help to increase feeling more secure & safe if you have one of those devices advertised like: "HELP, I'VE FALLEN & CAN'T GET UP!"; or better yet, leave a copy of your will on the running board.

Hope this helps a little for one to choose jack stands.

Mentioned by H.L above -and for those who are new to the market, below see what I am currently using bought in the early 1980s...

...but not by themselves. The double standard of support (anti-Fydrich effect) called upon here.

So now you see my interest in this now?

OBTW, asking price (or best offer) is $7.50 on Ebay. Shipping extra.

He seems to want to get past them too...

Personally, I would be afraid to actually sell these to someone. Liability aspect. Mine are going to the dump after I cut one of the legs out of it.

It would never be a bad idea to Google & read auto forum articles about "Jack stand failure".

Other jacked up & supported vehicles involving failures causing accidents & death that are often mentioned include but are not limited to auto jacks tipping over; hydraulic jacks springing a leak & failing; concrete blocks or cinder blocks crushing all of a sudden; etc., etc.

Just sincerely hope reading these searched forum failure articles can make one think twice before crawling under one's jacked up Model A Ford with cheap or homemade makeshift jack stands.

Hein-Werner USA Made jack stands Click

Interesting commentary from the only respondant/rating that gave them 2 stars (out of 5)

No longer made in USA June 7, 2014
gtthrills from Iowa
(read all my reviews)


" Very disappointed!!! I purchased these jack stands a few years ago and they are great! They were made in the USA and the quality and workmanship was excellent. I purchased another set a few months ago. I noticed right away when I saw the box that these were NOT made in the USA. Upon opening the box, I found that they say "Assembled in the USA". What that means is, they opened the box that was shipped from another country and inserted the yellow extension (USA cast into side of it), then close the box and ship it to you. I am willing to pay more for a quality product that's made in the USA, but not for this! Buyer beware!!! They are no longer "Made in the USA"!!! "

I bolded the part that's probably important given H.L.s failure mode analysis. Others who eschew a non-double locking stand may still have to look elsewhere.

We really don't make much any more in this country. This troubles me.

As JoeK points out, the extra lock is BS,,,,you can't move the latch pawl with weight on it,,,so what is to be gained?

Also, JoeK, those tubular types are fine for storage or smaller stuff,,,JMO
 
Another most compassionate safety precaution for those who never drove vintage cars with tubes in the tires whereby flats occurred more often on back roads.

Anyone care to share experiences like jacking up a car with a jack on the shoulder of a highway, (hard surfaced or gravel), removing the wheel with the flat tire; then experiencing a large truck zooming by causing the raised vehicle to fall off of the jack?

Next, if it was not life threatening, the jack may not always fit under the lowered axle?

Just like an old Laurel & Hardy Cartoon ....... FUN, FUN, FUN!

I bought 6 pairs of those cheap pieces of crap back in the 70's when K Mart had them on sale. Not only are 3 legs very unstable, but one of mine folded up and I was under the vehicle. Luckily the ground clearance was enough so I wasn't hurt. Those things need to be melted and made into Model A fenders.
