norWISequipment Lesson number one to avoiding whiplash,always keep light sideways pressure on the bale. Even when you're getting pulled sometimes the front guy slows a little in a soft spot an then WHAM, broken bale or whiplash.

norWISequipment very true

"hooking it" is what we tell the new guys to do to avoid the jerk. Hooking it, alot, makes for a loose bail.

Tax me I'm Canadian they are fun to operate.

I've run 657E series scrapers with 35,000 hours on them.

dcugseth they never retire the older ones just keep rebuilding

A lot of 627Bs and 637Ds from the 70s are still running.

pretty comfy in the newest ones H and K, other than those models they're all back killers

That's right. They are 700hp each and take a minute to self load, with two you are loading with 1400hp and 30 seconds per scraper to load. Hook up three and you have 2100hp and 15 second loads. Scraper are like Voltron. The more you hook up the better it gets!

vantagetes Scraper Voltron... that, is awesome. What's the longest (feasible) combination you've ran?

rangerman375 8 657E scrapers, that's 8800 horsepower on one cutting edge. Even with 3 you have to be really careful on not digging too deep or the hydraulics cant lift the bowl back out, and heaven forbid if you hook a big rock. Jackknife city, and someones ending up on rear radiator or breaking a bale. Takes a lot of people that know whats going on to do it right.

Not very boring when you are ripping around at 50km/h and turning out a load every 4 minutes.

certainly productive!! how many tons of dirt you you get moved in a day running like that?

About 4500yd3 in 8-9 hours.

vantagetes seemed like an awful long time in the cut with first can. but very nice equipment

Chuck Leahy the dirts real silty and sandy so it takes a bit

10, 1 and 4 are the pretty standard breaks doing construction here.

vantagetes so are you working a 12 hour day in the west?

Read the grade stakes. Or if you are stripping topsoil like we are in this video take the black stuff to the big pile.

thequattro20v read the grade stakes, they are also laid out to the contours of what is being developed, a good scraper hand will know how deep his 627 or 657 cuts when using the grousers (commonly called corner bits by most).

vantagetes Well that was simple enough, even for me. :)

Eddie Cardinal Nice to know, i don't know if we have a scraper in Finland at all. Never seen one. :)

The tyres should last longer than the machine in these kinds of conditions but in saying that over all they take quite the beating in general purpose use

If you spin the tires at my work you get one warning and if you do it again you get sent home. Tires are 10k each and are the biggest maintenance expenses for these things

Nah just getting rid of some of our old junk.

ahh i see. thats good i dont like the f series scraper anyway
