Surely that's a bit of overkill?


not if it has to 'reach out' any distance. Cranes are rated at a lifting
point close to (or in between) the outriggers.

He shouldn't have to boom it out very much, he's launching in a hole in
the ice.

Correct Scotty.... 34 tons is dead lift with the boom at max elevation....
start lowering that exponentially with every degree of angle..... at 45
degrees it will be at max capacity at maybe 4 tons.

I usually use a 150 ton crane. That has a hard time with a 42 footer.... at
20 k.
