The world's largest concrete pump—a 190,000-pound machine with a 230-foot boom called the "Putzmeister 70Z"—is being sent to Japan to help the troubled Fukushima reactors, reports the Augusta Chronicle. "There are only three of these pumps in the world, of which two are suited for this work, so we have to get it there as soon as we can," said the owner of the Georgia-based concrete company. "Time is very much a factor." The pump will pump water at first, but later will be used to move concrete to entomb the nuclear material, as was done in Chernobyl.

I've seen this thing in action. We used it to pump concrete for a girder that was 24' high x 14' wide x 250' long that was 180' in the air. We could not build it on the ground because they don't have a crane that could lift and place it once it was built.

It's not that much bigger of a pump. More so a lot longer boom to reach areas that are to far to drive a truck to.

You can still only put two maybe three concrete trucks at the rear for pumping. They have to use a retarder in the concrete because with that much boom the concrete starts to set from the friction before it gets to the end of the boom.

By the way. That's not the worlds largest concrete pump. We've used larger on high rise buildings pumping 30 plus floors from the ground. That is however the worlds largest concrete pump on wheels.
