The Left Coast Lifter is a barge and crane currently operating in San Francisco Bay, employed in the eastern span replacement of the San Francisco – Oakland Bay Bridge. It is being used to emplace prefabricated steel deck structure box segments on the main span.[1]
With a boom length of 328 feet (100 m), weighing 992 short tons (886 long tons) and having a 1,800 short tons (1,607 long tons) lift capacity, it is currently the largest barge crane ever used on the U.S. West Coast. It may be used to dismantle the old eastern span, but that is unclear as the current operator, American Bridge-Fluor does not yet have a contract for the demolition.
