Types of scrapers...Explained

Thought I'd try my hand at a voice over video...shoutout to my friends at Gilliam and Sons for having me out to film their scrapers.

A great explanation of the types of scrapers. I'd never seen an "auger "type before.

My interest in diggers and trucks, started in 76, my pals dad took us to a large earth moving site in s wales, uk, I was only 10, we spent the full day riding in Terex scrapers, and Cat d9 dozers, I was so exciting, since then I've loved all big construction jobs and machines, still have a big interest, 40 yrs later.

Very informative Scott. I’ve worked around scrapers on and off for years but you mentioned a lot of things I never knew. Thanks Scott 👍🏻

I ran one of the cork screw scrapers as a test loaner from Caterpillar when the first came out
I was running a 637 at the time, but Cat sent the Auger out to see how we liked them
I liked it but was glad to get my 637 back

Was in construction a few years and only knew of the one kind of scraper. Really cool information, thank you 🙂👍

Couple of things about 623's. They actually do have an ejection wall as well as the underneath one. They can also have teeth on the bottom of the bowl to help pick up material. Also, if you're picking up heavy clay, when unloading you can run the elevators in reverse to help break it up a bit. Also, at 3:10 I'd be really shitty if he was rocking around like that. Scrapers are already bouncy enough, no need to mess the pit up as well. Also another thing to mention (about all the scrapers) is the cushion hitch. When picking up you lower it, so the bowl is solidly connected to the cab. As you take off, you lift it up and it uses some sort of hydraulic magic to make the bowl 'cushioned'. I learned the hard way when I was first driving them. I forgot to take it off and my head hit the roof lol.

Thank you for a good basic explanation without getting to technical.

Cheers from Oshawa Canada. In the early '70s I'd skip school to go watch the old school Cat scrapers when they widened our 401 highway. ....no to get a sun umbrella, which usually Construction was the name, all painted orange.

Actually the paddle type scrapers have both a ejector and sliding floor to unload. When you unload, the floor first opens to dump the load. Then when the cylinder retracts all the way a switching valve automatically switches the ejector cylinder to push the remaining dirt out of the bowl. Then it does everything in reverse to close the floor. I used to work for CAT. Also My boss has a 623b and 623e. I also seen videos of the auger style in gypsum mines. They have a little set of ripper mounted to the back similar to a moto grader so when they are loading they pre rip to loosen the gyp for the next pass. Everything else was good info. Great video👍👍

In Australia we call the 613, 623, 633 etc Elevating scrapers - haven't heard them called Paddle scrapers before but it is easy to understand why some people do. The first "elevator" scraper I saw was on a road job in the Northern Territory back in 1969. It was a Cat 623B.

Later we got a Wabco B70 elevating scraper [possibly the only one ever sold in Aus]. Over 18 months it probably had about 50% down-time due to breakdowns but when it was sold off the new owners were achieving over 90% availability. Either we finally fixed it - or the new owners had better fitters than us!

Thanks for the lesson the numbers always confused my before never had it explained.. ...👍

[Umael]

Was wondering about these.
Have never seen one here in sweden,
seems rly effective in certain projects.
Thx for the video.

[tedhansen]

This is cool information. I thought I new the #ing system already. I love watching scrapers work. They are some of the coolest earthmovers.

[mambo]

Thanks for the cool videos we run 3 627e push pulls at our company and also a cat challenger and 9400t John Deere with pull pans

[MrLaTEchno]

My thanks to you, for the work efforts and upload.

[BillRayDrums]

Loadin' bowls... yep I've done that but not in a scraper!

[neftalirosado]

Wow, Excellent close up and perfect job ! 👍🏽

[BillRayDrums]

You should go for a more "Attenborough" accent and talk about them as if they're strange animals.

[spritfrost]

We have two 657E auger scrapers in our limequarry in denmark aweaome machines👍👍

[DieselandIron]

This was a really well done video. Those auger scrapers are awesome but I've never seen one in person.
