Ramp Removal
Never a dumb question. The dirt is pushed into the corner in a steeper and steeper pile and the back hoes "pass" the dirt up to each other until there is not enough room to do that anymore. One hoe is left in the excavation and a new one with an extra long boom (arm) on it is brought in, which sits above and outside the excavation, to reach down into the hole while the bottom hoe feeds it material. If it is hole is too deep for the upper one to reach, a large box is lowered into the excavation for the lower hoe to fill and the box is then lifted out and emptied. Once all excavation is complete, the hoe is lifted out by crane. Hopefully this answers your question.
