@peterahjorter There are two engines! The front controls hydraulics as well so sometimes you want full hydraulic power but less pushing power hence the need to control them independantly. Also in corners the back will push the front around if left at full throttle.
It can be called a can or a bowl, people always call different parts of different machines different things. Its even as bad as calling a whole machine by a different name like people referring to a skid steer only as a bobcat or in the uk a backhoe can commonly be called a jcb because theyre popular manufacturer names. Or like calling the arm on an excavator an arm or a croup. Doesnt mean that somebody who uses a different word isnt an operator in my opinion its the exact opposite.
i like the presentation. You have some fun and enjoy the job. Dirty machines are paying the bills. i like mud and dirt otherwise I would work in an office not run iron.
A Lighthearted look at the beast! Don't be so upset people. I liked his presentation! a few errors who cares! I like the single stick! The 3 levers and the Bail arm lever were what I had to use for decades! Do they still have the button for setting the RPMs the same as others pushing/pulling you?I suppose they would have to as transmission problems could result. My favourite was the 639D Twin engine elevator was the best! But still preferred sitting on a digger loading trucks!
@specialks1953 It's easier to not think about what the controls do, just what you want the machine to do. I had someone ask me which joystick in the excavator did what and it took me a good 2 minutes to figure it out and tell them.
1970 in Scunthorpe with Merrimans using the older version of the 657,s we moved 18million cubic meters in 14 months thats mucking some achievement for 53 years ago.
The horn is the most important bit on that scraper as I'm guessing thats what you use to summon the Dozer to give you a push! Oh and Luke Skywalker cant ever drive that scraper - the sign on the window clearly said "Dont force this joystick" LOL
Love the Es haven't driven the Gs I think they're C18s powering them as opposed to the 3412/3408 configuration in the Es nice machine though thanks for the look
It's just a counter. If you're paid by the load or the cubic yard (or cubic meter) instead of the hour, it's important to keep track of how many loads you've hauled.
when you turn the scraper on a 90 degree angle you only want the front motor engaged, as the back motor will push you forwards instead of pivoting on the rear wheel
The scraper is a tricky bugger to operate, I had a trial run in a terex and I didnt get enough time to get used to the controls, kinda tricky trying to drive and watch whats going on at the back at the same time!
@25mfd These scrapers aren't capable of automatically setting up to make cuts at the same depth. It takes a while to develop a good eye for making cuts and fills. About 90% of scraper operation is by feel. I've got a LOT of hours and years in one and it's a matter of getting used to the machine and how it runs.
@robdog121523 These guys are double shifting eleven and a half hours a day and have been working in brutal conditions for the last month straight. Normally most stuff is kept nice and clean on my site but when it's painful to even just drag yourself to work every day because you are so worn out (big push before the end of the year shut down) things get a little run down.
@25mfd The answers depend on the type of soil you're working in, size of the scrapers, and the operators of both types of machines. In a scraper the size of a 657, they're designed for moving a LOT of dirt and a grenerally used for rough cutting. They'll usually cut out the dirt to within 5 tenths (6 inches or half a foot) before other machines take over.
@robdog121523 Oh and before I laid them all off I paid them a couple extra hours to go through every machine and give them a wipe and clean out behind the seats.
@Amed2012 As I stated earlier in the video you can toggle the gauges between the front and back engine. The gauges were on rear engine display while I shot the video, and it was not running.
Is that right? Maybe you should take a peek in the manual and see what Caterpillar (the manufacturer of the machine) calls it. Last time I checked they called it a BOWL.
hahah lol i got so confused i was watching another one of your videos in another tab so i started hearing a cat 657E scraper cold start when you played with your ac knobs i was so confused
@akechely Ok bro, I'll make sure every single one of our 220 some machines is in perfect factory condition. Or maybe since this on is being worked on by a mechanic and not being used for production when I took the video I will make it of this machine?
Loved your video man!!! Find it funny how this offended the 'militant asperger internet heavy equipment expert crowd'Bwhaa ha ha ha ha!!!:) made me kind of miss it................except for neck and back ache at the end of the day from years of gettin bounced around in this shit.
Maybe just to see how they have changed over the years,i have been frozen in winter and boiling in summer..no heaters or air con ( or decent cabs) for many many years,i retired a few years ago after 46 years of 12 hour shifts..enough is enough..my last machine a new D9R did have air con tho',brilliant...i also drove my name CATDW21 many years ago too..no auto gearbox or hydraulics then...clutch/ winch and a big gearstick + a donkey engine to start..the good old days,,no thanks..lol
@vantagetes After you make a pass, how do you get back to the EXACT cutting depth of the previous cut? Do these machines have some way of locking in a cutting depth so you make the same cut at the same cutting depth EVERYTIME? If they don't have this, i would imagine it would take a good eye to set the bowl at the same cutting depth every time. And be correct.
@UAL012 That's pretty much what i thought. Answer this...If you have an area where you need to make a substantial cut of say 5 feet or more, after a few passes, how do you check to make sure you haven't overcut the area? Grade stakes give you the initial depth to cut to but can they be used as a guide to determine how close you are getting to grade?
please if you are going to talk about a pice of equipment that i love you get all the facts right . that what pay the bills and feed your faimly be serious and take pride in what you do. what we do as operators is a dream for some and a reality for some to make history that future generations to admire
@UAL012 I recently watched a vid of the gomaco 9500 trimmer. I thought that was what the motor grader was for? Is the subgrade rolled after the trimmer is finished or is it ready for the next phase. (ie curbs and concrete/asphalt paving)
What is the purpose of dual engine control? Why would you apply throttle to one engine but not the other, or vice-versa, or both at the same time? Thanks! Always wondered this about scrapers.
@UAL012 Another question...Scrapers are used in the rough grade phase but how close are you looking to get to grade when using scrapers? What are the typical tolerances that you would want to get to? Also, how much can one expect of the grader operator to fix a botched rough grading phase? ie, an over filled or underfilled area.
It’s easier to feel what your scraper is doing with hydraulic but if you don’t mind less feel and wanna kick back with out flailing arms everywhere Gs are nice
Along time since i drove a 57,no heaters to keep you warm then,the fan blades were adjustable (rotated) and you could turn them around thro' the hole in the radiator guard so the fan sucked air in and blew warm air into the cab rather than blowing it out thro' the rad,also had to start front engine with a donkey engine...wonder if anyone here could /know how to do that....catdw21
@cummins35001 Who wants to be serious all the time. We've already gone over what climate control switches are, and I would hope if you're running a 657 you are smart enough to figure it out anyway.
How about you take a little pride in your iron, and clean it!! Also, cracked glass on at least 3 windows, 1 of your hood latches is up, missing the ashtray.......really bro, if your gonna give a tour, make sure your machine is presentable.
