A 200-ton salvage grab arrived in Sparrows Point over the weekend to clear wreckage from the bottom of the Patapsco River. The Dutch-made hydraulic grab has four independent claws that together can lift more than 1,000 tons. (U.S. Army Corps of Engineers)
A massive hydraulic grab arrived in Baltimore over the weekend as officials planned a Thursday opening of the deepest alternate channel yet for vessels to travel through the wreckage of the Francis Scott Key Bridge.
Officials plan to open the 35-foot channel for only a few days to let deeper-draft ships through. Traffic won’t be let through next week as crews enter the next stage of operations, which will involve lifting steel off of the cargo ship that struck the Key Bridge last month as well as using the grab to clear debris from the Baltimore harbor’s 50-foot shipping channel.
I don't know if this grab will by used by it, but the first crane that was brought to the crash site was used by the CIA in 1970s. The CIA used what is now called the Chesapeake 1000 to raise a sunken Soviet submarine, the K-129. Part of the sub was brought to the surface, and the submariners that were recovered were given a burial at sea.
