Swedish to English Tech/Engineering Engineering (general) Wheels

Hello

I'm sure that in my context, it means this more or less:

https://www.amazon.se/Bygelhållare-för-företag-kan-köras/dp/...


The problem is that I just can't find a name for this in English

I've tried an image search and got hundreds of hits but none on English sites

I've tried things like "wheel buggy/frame" or "wheel jig" but it's never quite the same thing

Can anyone help please?

Thanks
