The biggest construction crane operating in Alaska is now at work on the expansion of Sitka's Blue Lake Dam, reports KCAW, which also has a photo of the beast.
According to Jessica Stockel, with the contractor McMillen LLC, the crane itself weighs about 2 million pounds. It has an overall length of 364 feet. The main boom can lift and lower 47,500 pounds. In order to carry that load across the canyon, the crane has 660,000 pounds of counter-weight.
