Excess strain on the jack is partly due to the hardness and smoothness of ones driveway. If Tarmac the jack will dig in, or rough and the wheels won't roll under as the jack lifts, so due to the radius of the lifting arm the rear of the jack will lift unless the car is pulled over with the radius of the arm as it lifts. This places massive strain on the jack and I've seen the two tun jobs literally fold up under an omega.

The bigger 2.5 ton and above jacks have wider wheels and a much stronger chassis. (Although avoid the trigger happy sealey jacks, they are bloody lethal. Ime. Zero control when lowering the car)

I have a 3 tonne Sealey jack, bloody thing, lifts beautifully but has a sloppy gear arrangement between the handle and the release valve which makes control difficult

Do you also find the cogs in the release mechanism don't engage when the handle is low, while the jack is lowering the dif for a spring change for instance?

The gears engage well (they appear to be perfectly aligned over the full travel of the handle) the issue is that they have big teeth with a lot of lash (I think that is the right word  )  and the handle is able to slide from side to side which introduces more free play. The release valve seems to need a bit of force to start to open it but it turns freely afterwards.

Poor workman and blaming tools

They do take some getting used to, but are fine once you get used to them .  Better jacks available for similar money on the rare occasions Costco sell decent jacks

For all its other quirks, I don't recall that being an issue with mine...

Cogs no, on yours. Trigger happy, defo.
