My company recently landed a large project in the FL area that will include quite a bit of pull pan and artic truck work. I was only recenlty assigned to the project and through some initial conversations may have discovered an issue with our plan of attack. The plan as I understand it will be to load the pull pans by running them accross the slope, which is a 2.5:1, to remove the material. The pull pans are a mixed fleet of Cat and Deere pans averageing about 18CY in size. The estimate calls out that we plan on getting 12CY (compacted) a cycle per pan. So call it 24CY per cycle for each unit.
My fear is that we missed the fact that because we are loading on a cross slope and the material is sandy that we may have the following issues:
1.: Wont be able to load the bowl very well due to the sandy soil. (More Cycles/Reduced Capacity)
2.: That the actual capacity will be greatly reduced even from the struck capacity because of the cross slope. (More Cycles/Reduced Capacity)
3.: We will have a quantity over run if we try to cut benches into the slope to load level due to the width of the scrapers and the slope required to be cut at each bench level.
(Quantity Bust)
4.: The scrapers wont be able to stand up on the cross slope or the scraper units will tend to drag down the hill. (Production Bust)
Either way I am curious to know what he scraper guys here have to say. I personally have not spent a ton of time in the seat of a pull pan which are big in FL. I have only run 621's and 31's and since I graduated college I have been able to spend much time in the seat in much of anything. But I hope that I can get some thoughts from the group here on what I may be facing here on this new project.
Thanks
