The cradle runs on 5 rails.Its hauled by a double drum winch,one line hauls up the others hauls back down.1'' line 8 parts on the main 7/8'' on the haulback 6 parts .The vessel is measured by some very talent ship guys to get the hull shape right .blocking is then set to conform to the hull.The cradle is lowered to acomadate the the vessels draught ,its floated in blocks adjusted and winched up.Usually they are repaired and relaunched,this boat was a deralict in danger of sinking.The company I was working for was awarded a contract by the government to decommission and dispose of this once proud ship.Lots of hazmat work and a bunch of plasma and torch work.

Nice looking old crane, it must have been really well looked after all these years. I remember the 40T's and 50T's being a real bear to work on because everything was stuffed into a smaller space than the larger Americans.

Cranes, Ships, and Landing Craft? Yep, you're going to need to keep posting pictures.

Some pictures of the 40 ton at work. An easy vibro job on the lake and then a workout with the drop hammer on some h piles for a building foundation. We are back at the yard resting now.

I gotta say my favorite is a Vulcan air hammer. I can say that now because its been years since we ve used one and forgotton the noise,broken parts and fuel bills for those 900 compressors.
