I thought the website was more engineery than slick, but more specifically, the up to 250 tonnes appears to mean, we can envision building one of a sufficient size to deal with that. They have mockups of a 2, 25 and 250 tonnes, and the scale of the big one does seem very large:

So is this reaction just getting caught up on combining images of the small model, with the load capacity of the (theoretical) biggest model? There's lots of things, like cranes, that have a fairly standard size and a few mega sized examples used for very specific tasks.
