Introduction movie hydraulic cranes

Seastate:

All standard capacities of the cranes are calculated at a standard seastate 0. If the customer needs to use the crane on a different seastate Promac will calculate the crane back to a different seastate. This means that the marine crane will be larger then usual to make sure the crane can handle the load in different sea conditions and there will be no damage on the crane.
