Does the 63m Putz run 5 or 4 1/2 inch pipe. If it is not 4 1/2 inch how do they keep the weight down?

it is 4.4 same as the 40m Putz. Conform is working on a 4.5 or 4.6 system that stays under the Putz max weight per foot/ full of concrete.

i think its the 5 sec boom does it puts web site has spec on it

Thanks for the info, how long before Swing matches it or better?

Putzmeister Germany has been making some long booms for quite a while. They made the first 62 meter in 1986, I have a picture of it although it has a 65M: posted on the main stage they still called it a 62. The technology is definitely there to go farther; we should see a couple of much larger booms over the next few years. It
