Push Pulling and when it ISNT viable.

Me and my expert father are having a debate.

We have a hog barn job with a 9’ deep pit, 100’ wide and 600’ long. That’s minimum as we don’t know our overbuilds yet.

We’ve done these before, but now our scrapers are push pull capable which is a change for us.

Dad says the haul to the stockpile is so short it isn’t worth doing (ie it’s faster for our 3 627G’s to be loading solo all the time instead of one at a time). I can see his argument, but the idea I was left with after working for that other major dirt outfit was that when you can, do. Is that a good rule of thumb or is that not always accurate?

Thanks.

what soil type how wet and how good are your operaters we did a lot of push pull on 600/foot cuts with 627b back years agao but due to rocky soils in the Joplin mo. aera we went to 621f three 621f will keep a push cat busy and we think it is the cheaper thing to do but if no rock you will cycle faster [ we work with a frend that runs 627g we per hr them @300. PER HR 621F we per hr @ 200. but you add a 200. push cat all depends on the job ] the 627g if they load alone we put @ 250. we do both but in the right place I would say if you run 627 and have the right pople hook them up [last hog barn we did was 120 by 900 over overbuild was 15 feet on sides and 10 foot on one end the other end was 20 foot ] we over cut the ends and put it back for free [ we got paid to back fill the rest ] just hired that done was all good in the end

Sandy. The top probably 3’ is material that a twin engine can efficiently get a good load. Deeper it becomes finer sand, not so much clayey as it is more gravely.

And you’re right. But we have no rocks here and it’s just too sandy for a 21 to pull out of a hole like that. We would be pushing them out of the hole with the cat.

I’m glad to see your numbers there. We ran 27b’s for a long time and upgraded and people think we are crazy we up our rates to $300 but it’s where they need to be.

jaclo what did you two decide [you and dad ] you both need to try new things with new eq you will both learn a lot and how to make the new grils make you MONEY that is y you do this ron

Still waiting on the final specs from the engineers. I think what we will end up doing is running one solo and the other two will push pull. The one guy is pretty talented keeping things cleaned up so he will concentrate on keeping the pit edges shaped up and I’ll have the other two operators hogging big loads out of the middle.

That’s the idea. They cost too much to run for free!
