Good push pull hands.. is this union

Look what we got with politions that don't want to work together

Nobody has to rock you to sleep after supper!

+crguy722 Those scrapers are called 'push -pull' because when they come into the cut they both hook up to each other. The one in front gets loaded first and this is done with four big engines all working together to PUSH him , then when the front scraper is loaded he lifts his cutting edge and the scraper in the rear drops his and then he is PULLED by the rig in front as well as by his own engines. At 5.00 min .n this video you will see the scraper in the rear pass by with that "big loop" that is called a 'bail' lowered onto a hook on the scraper in front. When both scrapers are fully loaded the rear scraper will raise his bail and disconnect from the front rig and both will head to the 'fill' . They will work all day as a team and will both stop together when they need a break. Thanks for asking.

+UAL012 not quite a 90 degree turn what they are doing is fine. nice thing about push pull its fine to pull corners with them as long as the power is managed properly and the bail is kept tight when being pulled nothing breaks

George Harrison sang that song My sweet Lord God says in the Bible the hills will be lowered and the valleys filled. Before his glory comes through

Thanks Mining shovel. Yes I have some of the 5130 as well as the 5130B on the same site that I'll be sure to post up:)

I'd be willing to bet there using the better clay for something else and that rocks probably better suited for fill

Snail darters, spotted owls and who knows what. If they can't find it they'll make it up.

Your dead right on that one. Its staggering the power they have if they want to use it to stop things being built.

Christopher Lovelock How true. I read a book once that was written by a head of the Atomic Energy Commision (maybe), Dixie Lee Ray I think her name was, and she had their quote that if they hadn't 'found' the spotted owl they'd had to made up something else. Maybe you can Google her name and find the book I hope I spelled it right. CHEERS Christopher!

Oh yes I forgot that one . The bird brigade have a pretty strong voice as well, a few years ago some rare 'bird' nested in a building due to be demolished. I think it cost the builders £80,000 to prop the building up while this bird hatched its eggs before they could pull it down. I looked up the lady you mentioned I see she wrote a book called "environmental overkill" - very appropriate. Cheers.

Christopher Lovelock That's IT! I had 2 copies and ended up giving them both away. A good read but it'll make you mad as a hatter. We don't know any of what really goes on but it will all come out one day! Cheers again!

they make 1:50 scale models ive got 2 of em

1/50 is way too small for me. 1/50 is about the size of a large matchbox truck. I like 1/16 to 1/18 scale trucks because you can actually use those for practical applications. There is a company that makes 1/16 scale cat models, but they haven't made this one yet, and the more I think about it I think I would rather have a 630 1K1/16 because then you can have A wheel tractor scraper that is a reasonable size for little kids as well as big kids to operate.

And it's really not too much of a stretch to ask them to do that either because they already make a D 11 T that is absolutely gigantic. The blade on that thing is A monster for a toy bulldozer it's a 9 1/2 inch SU blade. If you would like to see that bulldozer check out a video called fixing the D11T on my channel.

I'll bet that one if those guys is the grade setter and the other the superintendent. You never see one without the other it seems like

+onyourbikeuoldfart The guys walking around are not just scratching their arses. They serve several purposes; 1) one man is what is called the 'grade checker' , his job is to make sure the scrapers excavate to the required depth and not remove to much dirt. At $500.oo per hour for both of those machines it is well worth having a man on the ground to keep the rigs where they need to cut. 2) The other man is probably a 'soils inspector'. His job is to insure that all unsuitable material is removed from the cut. For example; suppose a grove of trees were there long ago and now roots were everywhere. These roots could cause voids in the soil if left and would eventually cause a structural failure of anything built on top of them if not removed. 3) last we have Paleontologist/ archeologist who are looking for fossils and other natural history remains. I hope this helps you and thanks for asking.

that's a grade checker

Just got through with a job where I had to do a lot of stripping so I understand what you're saying. Get bthe good and use the crummy stuff to grow grass on!

MOst companies ive worked for your lucky to see the surveyor once a week but then again ive never worked on a job this size
