Title Cantilever Cranes
Description This is a view looking west across the dam, showing the span of the great cantilever cranes. The last of the CBI cantilever cranes were dismantled on Sept. 12, 1940. Note the transverse beams inside the trestle towers on which monorail cranes operated while placing concrete beneath the trestle. Heavy construction equipment comes high. Upon receiving their notice to proceed, MWAK Co. immediately let contracts for $5 million of equipment and material, and by Jan. 1, 1937 this item totaled... These cantilever cranes (hammerhead) were specially designed by Colby Steel and Engineering Co. and Bethlehem Steel to 300 and 330 ft. double cantilevers. With a total of 8 motors totaling 408 horsepower they could both carry empty buckets at 600 feet per minute and lower loaded ones at 300."(Clifford R. Koester.
