One of the underground disturbances found by Staffs Uni was described as a ramp. If you accept that the dragline could lift from round the edges as shown in your video and it could get into the grave, as you accept they worked inside the quarry, how can they not be used at all at TII to dig the graves, exhume bodies?
I've shown you the mathematics of why the M&H model Mb could NOT have dug the mass graves and stockpiled the ex. If you can disprove the math or find errors in it then do so. Your mindless maundering about "what ifs" is pointless. At the T-1 quarry the draglines were excavating and stockpiling material for shipment, not just digging holes. The draglines would remove and stockpile ex in strips. They could then return and remove another layer of ex for shipment. That's how a quarry operates even to this day. Peel off the overburden and mine the desirable material for as deep as it exists or until your needs are satisfied.
Why are you still assuming only draglines were used at TII? There is no evidence that is all that was used. The Nazis could have used a different excavator more suited, or both a dragline and another type of excavator. You have been told that repeatedly.
Why do you weasel dodge that I have answered you question on numerous occasions? When are you going to address that there were different types of excavator available to the Nazis? When are you going to stop weasel dodging that the witnesses who were at TII did not say what type of excavator was used and we just do not exact make or model?????
There is only one witness that I know of who claims that other equipment was used at Treblinka. That was wagons and carts used to haul the cremains away from the camp to spread on the roads. Others claim that the cremains were simply thrown back into the graves. If you have a witness who claims that anything other than a "digger" or "machine" or whatever dug and stockpiled the graves then post a quote/link. I'm not interested in what you think the Germans COULDA' done. Just what witnesses said that they DID.
If the Germans had brought in a dragline large enough to build 45 feet tall stockpiles then just the three connected graves in Wiernik's model plus the area of the graves would have totaled ~2.7 acres or half the area of the alleged totenlager and that's not allowing for any pathway for carrying the bodies to the graves. That leaves two (2) isolated graves to go. If the M&H dug the graves, the resulting stockpile would have totaled ~2.8 km. in length.
If you innumerate fools can't cope with the very simple mathematics of calculating a stockpile from an excavation then don't whine at me about what maybe, coulda' or shoulda' been done. Your vague, "Well, the Germans had lots of excavators" is just mindless bullshit. Wiernik said that one excavator dug "the ditches". Y. Arad, ARC et al. claim that the M&H dug the graves. You claim that the M&H was used at T-2 but only to tidy up after the mystery machine was sent away.
If the Germans had dug graves with the M&H they would have dug more reasonably sized graves. Since 25 m^3 per meter was about the maximum stockpile it could build, that would define the dimensions of the graves. They would have had to increase the size of the totenlager considerably but that could have been easily done. Most likely scenario for the Germans to dig 10X25X50 meter graves at Treblinka would be them bringing in a small fleet of dump trucks and hauling the ex down to the quarry at T-1.
No cremains, no graves, no holyhoax. Finito. End of story.
