The Peninsula Crane and Rigging hydraulic truck crane used to transfer the steel from truck to building has capacity to lift 75 tons. That rating is for loads within a 6′ diameter of crane center bearing (can you think of some object that weighs 150,000 pounds and is less than twelve feet across ? )
For our project the more important statistic was the ability to move up to 9,000 pounds at 80 feet from the truck.
