Yes 😂

zordu

They still running the 660s

This is Production

Yeah then whats your problem?

Good

Yes, a D8 is a mis-match with a 657.

So true. A D8 is not a small machine. The 657s are just enormous.

You can't hardly see the exhaust stack from a 57

Slope board Sally gives a clue where she is

After running 57s anything else is a dink

Even with some worn out track shoes!!

Jsjsks

Its relatively easy pushing pans guys lol

The scraper should never stop, that way the push cat can just catch up to him and make contact without a bang. Hard thing to teach scraper operators.

Tu te Kohe Struck load capacity on a 51/57 is 48 yards. With side boards and heaped load 50 to 53 yards

33 cubic metrs of clay,is a lot more than 47 (metric)tons,i think,it should be around 60 tons.

J Cs Figuring 50 yards average heaped load at an average of 3000 lbs for most material that works out to 75 tons

That is cool, I like it and it’s a BEAST! But may I kindly ask why they do not produce a scraper that would be able to self load, while keeping proper load speed of course, but do it without the help of a pusher dozer or Mr. Chuck ‘Plz don’t push me around’ Norris? Serious question. I’m sure it’s a size thing, it would be a behemoth, this I am sure of.

I think we can all agree this guy is going to have to run the coops

Low elevation they're already hot plus low humidity.

A diesel engine is much less harmful to humans because diesel particulates settle

Turn em up

Is Templeton from San Marcos still working

bob dyer GPS receiver

Donald Clark.. Who, me? LOL.

Just like the new D11's they dont sound good at all!!!!!!

gm16v149 the scraper is dual engine by the way.

Yes, thats used to push more dirt. When you mount a blade like that on the side you have more dirt you can push around.

Those D9Ls were so powerful

It looks like they are working to grade and that is the end of the cut so he has to take what he can get.

Cakes Man could it have been the end of the job and just needed a small quanity of dirt to be moved?

Cakes Man unfortunately a video is a brief snap shot of what is going on.

Agreed, an 8T is a bit on the small side to be used as a Pushcat, normally.

I see D8s pushing all the time, but they're pushing 621s 😂

Most people mistake wet silt for clay, big difference.

That decomposed granite can get some tires

NO..you are not

73 actually. If I hadn’t Googled I wouldn’t have believed it.

Of course the boss agreed... He didn't pay for the fuel or maintenance

Why not? Sounds smart too me.

I agree, only reason the bulldozer needs to be there is rip, push to grade and or push out a stuck scraper, if it's got 2 engines and a good operator it will keep up if not ahead of singles been push loaded.

If you don't like the scraper hand

I would have thought so too...esp with twin engined scrapers. Noticed only 2 ripers on the D8...is 3 too much for it to handle in hard clay?

True, and this one hasn't been fully loaded the entire video. Using 3 engines for the full push is a waste of time and money.

I ran a 621 , the pusher was a D8, poor guy had to try to catch us.

You are right on ,from N.C.

The site I'm on, I regularly see 3 621s idling away, waiting for the push. The foreman doesn't say anything. Mind you the material is rough. Lots of rock in it. They had the D9 down for 2 days converting it to a single ripper because there's so much rock in the ground.

Exactly, pretty rammy cat skinner also!

Richard Weemer Was it fun?

Ran a D9G with ripper at Clinton power plant in Jan 1976. Pushed some 637's I believe. Shelbyville.

I was just at the Decatur plant a few weeks ago on a tour. Very impressive operation there. I was surprised at the many different machines they build there. Mining trucks, large wheel loaders, scrapers, the 24 grader, totally awesome! If you ever get the chance to go, take it! Well worth the time and travel. *edit- they also build compactors there, and I think wheeled dozers. They have the first ever 785 haul truck parked out front of one building and what looked like a first generation 657 scraper in front of another. Truly amazing how far their machines have come after watching this 57 work. The one in Decatur didn’t even have a ROPS.

I bet your welds suck

657s have a 70 yard bowl

@@jordank943 I ran them for 20 years , The company's largest open-bowled scraper, the Cat 657 has a heaped capacity of 44 cubic yards with a rated load of 52 tons.the 666 and 660 scrapers had a huge bowl and was rated at 40 cubic yards struck and 54 cubic yards heaped (even more with sideboards).I worked for a company called McCoy construction and they tried to stretch the 57Bs and side board them but the extra weight kept breaking the goose necks and cushion hitches . 😎

@@jordank943 Some of the 657 E models I ran had side boards and apron extensions but never held even close to 70 yards and they were prone for cracking the hitches and goosenecks with all the extra weight.

There is a limit as to how much traction you can get onto the ground. They are not underpowered. We seldom used the back engine when being pushed but let the pusher do most of the work, using only the front engine. When you are loading the weight comes off the back wheels and there is no point spinning them because that does nothing except rip up tyres. Yes they will self load fine, but the bite is a lot less and the travel much longer in the cut - it is far less productive. If you have a couple of pushers they load in seconds and there is little tyre wear. To help you understand lack of traction on the back, the box does not go down by gravity, like a rope scraper, but is powered down. You can power the box down and leave the back wheels six foot in the air.

Guessing the cost is well over $1,000,000 usd

Backpacker1uk I ran a TS14. Yes, I know... It was kinda small.

@@kevinjasper6620 TS 14 single engine up front was it not

Backpacker1uk nope, double barrel

@@kevinjasper6620 The T in TS stands for TWIN.

Geo Thomas when your chasing grade behind scrapers and spot ripping for them three is too many. You can rip faster and a lot of time the rip marks are more to show where the cut is than to loosen once your closer to grade.

A good push dozer always works the dirt waiting on scrapers That's its job

That's Style

Took so much effort because they didn't know how to do it.

He is trying to break you in the right way

Brian Gardiner I don’t know but I could take a guess at it. They do have a couple of D10T’s on site so it’s not for the lack of a big dozer. I’m guessing the reason is that the job is nearly done and they only have the one scraper in the video working. There’s no point having a big dozer hanging around for one scraper.

That 8 seems to be doing just fine. Why use anything bigger?

Who you working for
