In the US they call them jack stands for some reason. We call them axles stands, because after you have jacked the vehicle up, you put the stands under the axles....when cars had axles that is.

There could be another reason they are called axles stands - when they are made from axles ! this was a pretty common thing in days gone by. These aren't used often now, but I had one propping up a machine the other day, and took a photo before putting it away. And another one too...we have half a dozen.

Maybe called jack stands because they're adjustable although you really can't jack them up. Most guys not in the trade wouldn't have access to old axles to make them or a way to get a vehicle as high as the one on the right. Great idea.

Nice old stands but in today's world its a lawsuit waiting to happen if some numbskull used them wrong and dropped the vehicle.

True that. Many of the China made stands I see these days scare me … and I don’t use them enough to justify pro grade … so I wind up load sharing with a stand and a jack (or two) …
I’ll use my ramps if the wheels can stay on.

There are some combo rigs … I had a bigger version of these but seems someone else needs them more than me …

Part of the reason they are called “jack stands” is due to thier resemblance to the old style bumper jacks used on most cars in the past.

One also used them on the jacking point of newer cars to hold the car up.

Actually, the more round a base is, the more stable it is. Circles spread the load better (consistent) than polygons, which have weak/strong spots. My guess is that square bases are easier to construct (cheaper), and over engineer, which is probably why they're so common with jackstands. They're not necessarily better, though.

Round base has one contact point with the floor. Common square stands have four. Square stand is much more stable especially if the load isn't centered exactly. Or you can use a hybrid like this.

That is not accurate. The instability of a load is the exact reason why a round base is a better choice.

A square is more stable than a triangle. A pentagon is more stable than a square. A hexagon is more stable than a pentagon. A heptagon is more stable than a hexagon. An octagon is more stable than a heptagon. ...and so forth. Keeping adding sides and what you're essentially creating is a circle.

A polygon's edges and vertices create weak and strong points. A circle is evenly stable.

Tilt that round base stand just slightly, and only a half inch wide section of the base is touching the ground. Tilt the square base stand with legs 6 inches apart, and you effectively have 6 inches touching the ground, plus no tendency to roll like the round base style.

The whole point is to prevent tilt. Once you've reached the point of tilting, all bets are off, as you've exceeded the limits your device was designed for. A circular base prevents tilting better than any polygonal base. That's the use case of a jackstand.

I've had one side firmly on a stand, started to jack the other side when I see the stand start to tilt a good bit before I realized it, and stopped. If it was on a round base, I could imagine the car would have fallen over to that side before I knew what happened. Just my observation, right or wrong.

This seems like a fantastic idea if you have the clearance to get the stand under the area where you want to jack up and it has enough lift range. I usually jack up, put a stand and leave the jack as a backup. This device accomplishes it all. I like it.
