I'm doing some research on the concrete industry and trying to come of with a ranking of concrete pumpers.  I hear Brundage-Bone is the biggest.  Anybody have a sense of size in revenue and who the next five or so players are?

brundage-bone is the largest pump company in the world with 600+ pump trucks. pumpco inc is second with 300+ not sure who is after that.

I THINK THEY SHOULD ONLY GO BY THE PUMPS THAT ARE PUMPING,AND NOT ADD THE ONES THAT THEY GET TO SALE .THAT SHOULD FALL UNDER BIGGEST DEALER.
