Tetra Hedron, a heavy (1763 tons) lift marine crane

Dennis Makowski posted
For perspective that's a 2250 boomed down directly underneath the bohemith.
[The comments disagree that the crawler crane is a 2250. But the fact that you have a crawler crane as your "utility crane" is empressive. The video below has scenes with the utility crane boomed up so that it is easier to see.]

Got one of her boomed up on lunch , check out the six million miles of boom hoist cable
The brilliant minds of humans are smart enough to design and build a floating crane barge that can house 300 people and lift objects weighing as much as 3,526,000 Pounds [1763 tons, 1600mt]. That is not speculation. That is what the Tetra Hedron barge crane pictured above can do. 
The Tetra Hedron in drydock, this is one of several photos you can scroll through. Including one with both booms up, but I could not get a link for it so I copied it.

It looks like Manitowoc made a biggie for Tetra also:

  1. The platform of a mobile crane can either have traditional wheels, wheels designed for railroad tracks, or a caterpillar track, which is useful for navigating unpaved and uneven surfaces. Mobiles can be used for demolition or earthmoving by replacing the hook with an appropriate tool, such as a wrecking ball or bucket. Telescopic cranes, with a series of hydraulic tubes fit together to form the boom, can also be mobile. Find out more:

  2. I wish more authors of this type of content would take the time you did to research and write so well. I am very impressed with your vision and insight. Georgetown crane rental

  3. Folks, per the web site this crane is owned by a company called Epic Heavy Lift Services. They have a flyer on their web site that tells all about it. The flyer list the deck crane as a "Manitowoc 14000". Don't know one from the other myself, but I figure the owner would!
