saw quite a few different pumps watching an orientation video.  why do people hard core A frame booms?  i get the 'main and third' al day is pretty easy though i just don't get it?

With all due respect ,  would you define "hard core A frame'

B-section maxed out.  C-section and D-section pipe in a straight line.  use only main and C-section rams during the pour.

that is a true sign of a lazy operator who is choosing not to get any better at pumping. time to try out a better company.
