I think that is a bit pessimistic. I took out two swimming pools, about 140 tons of well-reinforced and good quality concrete with it. Plus several jobs of easy "flat work". It does shake things up a lot, but nothing has broken. The only real effect I have noticed is that the balls on the QC fittings have "hammered" into the couplings badly and the couplings are difficult to mate now. These are old-style sliding-sleeve couplings, of course. The newer flat-face ones may not even have this problem. I also had several hoses for the lift arms fail; but was that only because of the hydraulic pulsing, or was it also due to them being over 30 years old?
