This here piling mat that I'm sorting out needs to be tested with a plate test. And to do that I need an 8 ton reaction load. Following the by now normal steeeeep learning curve I learn from some that it is common to use a loaded 20 tonner's back axle, from others that I need a dead weight, like a 10 ton digger (no suspension). Where do I get a 'dead weight' 8 ton reaction load? (Keep it clean, please @Nickfromwales @ProDave) If I have 32 tons of lorry parked on my piling mat, and the test plate and hydraulic ram is put under the back axle, won't the test rig merely tend to jack the lorry back off it's suspension system? And thus invalidate the test? Here's an example of it done with a wagon (sprung) And here with a digger (unsprung) What I want is Vorsprung durch Technik, fellas! And it'd be good if I knew the right Technik.
