Cripes, that's scary ... I was given a set years ago and used them on the MGB when I welded the spring hangers. Never really trusted them and spunked up for some proper SGS ones when I had the van 3 feet up to weld the sills and new floor in . Bloody scrap compared to the SGS items . Glad it ended well...

There a was a huge recall in the USA from one of the big auto sales shops they look the same 2 years old? Same cheap manufacturing I would guess. Glad your head was not under it
That is nasty - I think the USA recall, the casting of the teeth on the top section was poor, rounded teeth. This is the Halfords "3 ton" version, shorter top section and thicker. Still made in China of course. This has survived years of use.
What confuses me is that you actually used that stand. You had it in your hand. Did you not think it looked at least suspect? If anyone is now worried about their own, put that cast bit across a couple of bricks or whatever and smack it with a hammer. Mind your eyes.
I agree ! I wouldn’t of thought that cast steel would be the best material for making these Well that was my first thought when I saw what had happened
Cast steel would probably be ok but cast iron - no. However, no doubt it's possible cast steel in a brittle fashion too if you cock up or don't care.
The pin through the hole ones are better but then you are trusting yourself to a pin. Which should be thick enough to not shear under load.. but you and the suppliers both bought the cheapest ones... oo look this roll pin is the same diameter...
Cast iron is stronger than mild steel but more brittle. Molten it flows more easily so casting well defined teeth is easier. Its often used in architecture for load bearing columns, Victorian era wood cored cast iron pillars can be amazingly tough. If the load on the original axle stand was exactly straight down then it probably would have easily taken the load. A slight bend from jacking up another part of the bus then it snaps..
Precisely, hence hitting it with a hammer. There are plenty of cast steel load bearing parts on a bus.
That's the one I bought from them a year or two ago when they were half price - only used once and then lent to my son for use on his Volvo XC70 - better warn him to check it.
