I wouldnt even attempt it. Espeically if there is any reach at all involved. Sure, its digging force may be 2600lbs, but dont confuse that with lifting force. Digging force is achieved by extending the cylinders....the direction they have most power. But lifting requires the cylinders to retract, where they have less power. Also, that digging force is MAX digging force. When the cylinders and things are at their optimal location and angle.
I'd say you are right, that those pipes are about double what you can comfortably handle. My 18,000lb old BH with massive 5" cylinders only gives a max lift at full reach rating of 2000lbs. And as big and strong as my machine is, I am sure I'd notice the pipes. No way would I do it on a BH92. And even if you "could" do it....how long do you expect the machine to last doing that any given amount of time at all
