The pump on these units are capable of 10,000 psi. If the cylinder were a 3.5" bore then it would take 10,400psi to get 50 tons. If it were a 4" bore cylinder, it would take 8000 psi.
The 8" cylinder would only take 2000 psi. Surface area becomes your mechanical advantage. That also requires addition strength in the materials used since the force acts on everything within the cylinder.
So, to answer you question. Yes, it may have a 50 ton capacity. Just by the skin of its little pump.
Compared to our Dake structurally. Anything near 50 ton on that frame looks scarey!
