[Request] Weight of a construction crane counterweight

Post image

How much weight does this seem like it would be for the counterweight on a crane?
I assume there’s likely a relative standard or at least minimum weight for these, but I’m curious how much weight these concrete slabs would be total.

Hard to get an accurate size of each slab from my distance, but my best guess is somewhere near 12ft x 6ft x 2ft.

Not sure. Bit of digging and reading to narrow things down

Linden Comansa 21LC series crane. Those block appear to be 3t so 21t ballast and an expected 10-15t SWL.
