Another demonstration that the key is the rigging.

| NTDOT The "Left Coast Lifter" was renamed the "I Lift NY." The crossbeam that it is raising weights 750 tons. |
The Left Coast Lifter was built in 2009 at an Oregon shipyard to help rebuild the Oakland Bay Bridge. It has also helped build the Tappan Zee replacement bridge (Cuomo) and rebuild the Amtrak/NYC Spuyten Duyvil Bridge. (During the Pandemic it was "unemployed" and stored in the Caddell Dry Dock on the north side of Staten Island. [slive]) It was unofficially renamed "I Lift NY Super Crane." The crane cost $50m. [sfgate] It paid a $70,000 toll fee to use the Panama Canal. [sitecert] It has a 328' (100m) boom and a 1,900-ton lift capacity. [gCaptain, has several photos of its Panama Canal transit.]

Lucibello Heavy Equipment photography posted four photos with the comment: "Left Coast Lifter, a 1873 ton shear leg crane. The barge was built in Portland Oregon by U.S. Barge LLC, now the crane was built and installed by ZPMC in Shanghai China. After completion the crane was carried over from China on a semi-submersible heavy lift cargo ship in 2009 to California. Lefty was specifically built for the Eastern Span Bay Bridge project in California which it competed in 2011. After that job was completed Lefty was purchased by the Tappan Zee Constructors and was utilized to build the new Tappan Zee bridge over the Hudson River starting in 2015 and wrapping up in 2019. The crane has been tied up at Caddell Dry Dock on Staten Island ever since."
Jon Hart: The crane was designed to be able to pass under most “harbor” height bridges with the gantry up, and boomed down. With boom down and retracted, and gantry folded down, it would pass under many inland waterway bridges, and fit in locks.
It was also used by American Bridge for a project where it lifted part of the Amtrak Spuyten Duyvil bridge for rehabilitation.
Liz King: I hear there are horror stories about how cheap and nasty AB were in its construction. They preferred to go with porta potties that they were too cheap to maintain then on board bathrooms.

I've seen a TV show about an really big marine vessel that has two large cranes on it. But I don't remember the name of it. I wonder if it was the Heerema Sleipnir that has lifted 15,300 metric tons. (more details)

This post has motivated these notes to start pulling together the information that I have about large marine cranes.

| Screenshot @ 0:04 of 0:21 video (source) [The video does pan around and catch most of the crane.] John Cox: That thing has 300 miles of cable Eric Mocker: The 10,000-ton shear-leg floating crane is equipped with two 180-meter-long crane booms and two sets of 70 m high back stay. The crane is operable with the control of 16 sets of main hoisting winches, eight sets of jib hoisting winches and 72mm and 54mm wire ropes which are 5,700 meters long each. The main hook is made of eight sets of 1,250-ton hook. The four sets of 2,200 kW main generators, two sets of 600 kW harbor generators and one set of 100 kW emergency generator produce electricity the crane needs. |

| Eric Mocker commented on the Screenshot source Here it is picking a 9100-ton top side for oil/gas production. |
