Cat 657, front engine 600hp, rear engine 450hp, bowl capacity 33 cubic metres. With the assistance of the D8t, it's loading it's 47t of clay in less than 30 seconds. That is real production.
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.
There are a couple companies here in California that run scrapers way bigger than 57s and they are Cat 660 s and Cat 666s or we call them triple sixes . 60 yard three axle scrapers and the triple sixes are twin engine.
@@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.
As you can see the 657 isn’t getting a full load, two tractors ( 9’s or 10s ) tandem pushing is needed to achieve the optimum production, a valiant effort by the 8T operator though.
Clay... In California it's mostly decomp I spent a lot of time moving mountains and filling canyons for the ridiculous housing market. Had a really big job some years back in temecula where they moved one mountain to fill a similar size canyon to build houses and golf courses over both! the canyon was 7 miles from the hill, I push loaded scrapers and ripped up decomp for 6 months! I remember very little clay LOL
Usually you don't use this small of a dozer to push with. I am guessing it is near the end of the job and everything else has been shipped to another job. Talk about a jack of all trades. This D8T has a sloper attachment and a GPS antenna for checking grade. I think that is what he was doing when he was using his dozer blade to push dirt with near the end.
You lads all seem to use the "Pusher" D? for loading and not what we were always to do which was for topping up. back in the day 60s&70s we had to be half loaded before the "Pusher" started to push us, if you were not self half loaded you ended up taking the long walk back to you're car. We only had 631s and a D9. By using the Half Loaded method production was up by 40% as against the waiting for the "Pusher" to load us. Happy Days.
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.
Poor little Dozer I can remember the days, when I was made to push 627s with a D7h😭 wishing I had the 8k or 9g, then years later I was on a brand new D9L pushing 631d's wasn't allowed to push them with 10L too powerful could tear the floor out!!!!

You don't really get the size of these 657s until you see how tiny that D8 looks pushing it They better get a push plate welded on that blade though before it's beat to hell lol
Never operated a 657 but operated a 627 and a 651 and a 621 so I suppose the jump is about the same from a single to a twin only bigger, when the dozer was busy ripping I used to push load the singles with the 627, first time I started doing it every one said you can't do that but the boss agreed with me and I kept up with the singles.
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.
Push Pull would have been more cost effective here. And, let the little D8 rip away. Also the operators should be required to fill that bowl or go home.....TOO much wasted time.
You know that's a D8 pushing looks smaller don't it ,,657 is near, 240k lbs empty ,Loaded over 350k lbs and does 50mph loaded, tires 10' tall and burns roughly 300 gal in 10hrs between twin diesels.
Why arent this Scrapers equipped with more power say double the power? Or is the tires limited traction the problem? I see them pushed and pulled and wonder if they are underpowered
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.
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 had sum older guy that was runnin on an 8 on a 9’s job, dude was gettin so mad i wasnt putting my can down at the right time. i bout knocked gramps out 😂.
Not a big fan of the new fangled high drive set up, seems to put an awful lot of stress on just a few track pins and 1/3 of the sprocket and as for that relentless "CLACK CLACK CLACK" from the tracks, enough to drive a man insane. Give me an old school D8 or 9 any day of the week!
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.
LB3 is a scab outfit meaning they pay their operators minimum wage.....I know I worked on this very site for David Peed ...running the same model # tractor
I know this question is from 3 years ago, but look at that load speed, 20 second from the bowl drop, to the skirt close. Show me any excavator that can load an ADT with 20 tons in that amount of time...

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

Low elevation they're already hot plus low humidity.

The D8 looks small beside the 657. Cool project to be involved on. Super video 👍
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

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 😂
Is it a bad idea to drop the rippers while pushing the scraper?
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.

Disappointing neither of them has a V configuration engine. Oh well. I guess the scraper has a C18 but not the same sound as a 3408.
Donald Clark.. Who, me? LOL.
Just like the new D11's they dont sound good at all!!!!!!

Those D9Ls were so powerful
Guy running around with half a load???
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.
D10/11 would be a lot better, the scrapers are lifting with half loads

Don't ever blade off windrows, they are free loading material. Seems whenever I , as a foreman, had to teach the pusher to stop it.
I can understand. Dozers cost heaps too run, why burn more diesel than necessary.
@@lesflynn4455 The point being the windrow is material that is already loose, doesn't require effort to loosen it to load.

Not the biggest in history.
Maybe currently.
660 and 666 bigger
Love the batter blade on the dozer no need for a grader aye
Man you need at least a D10 to adequately push that monster
Interesting D8 that with it's side blade! 😍
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.

why is the D 8 NOT RIPPING AND THE SCRAPERS PUSH PULLING
rogerofrhodri it’s hard to push pull with one scraper. It’s got to be a very short turn around for that.
On some jobs twenty plus of that size alone and two dozen smaller 30 cubic yards for operator schools.
Why don’t the just use excavator and dump truck ? Surely a dump truck can carry more at a faster speed
I know this question is from 3 years ago, but look at that load speed, 20 second from the bowl drop, to the skirt close. Show me any excavator that can load an ADT with 20 tons in that amount of time...
For shorter runs nothing is as efficient as dozer and scraper combo
Why bulldozer is pushing scraper
He needs a pushpull partner , so the D8 can go do some trimming
Mr 8t has it!
