The weight needed depends on the capacity of the crane. It has been a long while since I had anything to do with cranes. But say you were proofing a 10,000 lb crane and the procedure called for 125% of capacity. So you would pick out weights so the total was 12,500 lbs. The next crane might be a 15,000 crane and you do not have weights that total up to 18,750 lbs . So you use somewhat less and label the crane as derated to whatever you can do.
