    One project I was on, the safety man was concerned about the braking power of the 657's, and the boss told him those guys have the best brakes in the world. If they need to stop, all they have to do is drop the bucket, and it'll stop fast enough to pitch the operator through the windshield.

      Lol - that's the truth! I bought an old Cat 212 grader a while back and the brakes didn't work. The guy selling it to me said "don't worry, you just drop the blade - best brakes in the world!". Technically true, but I still fixed the brakes.

    It all seems mundane and innocent until you realize that’s a D11t pushing the scraper. The dozer weighs a quarter million pounds and has 850 horsepower. The scraper has another 950 horsepower. All that power means they can load the 40 yard bowl in about 40 seconds.
    It’s absolutely incredible.
    One seamless motion and the scraper never stops moving forward. Super efficient.

      Exactly, time is also money and on a government road building or civil engineering contract it’s about moving the max amount of dirt in the minimum amount of time this too is efficiency , taxpayers are footing the diesel /labor costs so price is irrelevant at this stage, again efficiency in action the dozer is productive in both directions of travel , ripping and pushing

    Fantastic
    A dozer spends half its life doing bugger all but reversing and using fuel to do it.
    Reverse ripping after a scraper push in rocky soils is a no brainer .
    See how that cat dozer does not flinch with the weight of the dozer blade counteractng anything the ripper comes up against?
    Wish i had invented that idea!!

    • @ArthurDentZaphodBeeb
      @ArthurDentZaphodBeeb Год назад +3

      Reverse is usually higher speed and adds a lot of undercarriage wear, so ripping at slower speed in reverse probably adds to undercarriage life. Win win.

    • @gullreefclub

      @@ArthurDentZaphodBeeb​​⁠​​⁠​⁠​⁠I think the concept of reverse ripping is interesting and I can see multiple benefits to doing it such as time saving, fuel saving, reduced wear and tear from making two 180’s if ripping going forward, as well as potentially reducing the occurrence of accident(s) from not spinning the dozer twice to rip going forwards and spin the dozer again so it can push the 657. However I do wonder about undercarriage wear especially on the track chains and possibly the drive. Look at how the tracks move on the machine when pushing forward and then watch the tracks where backing up when the machine is not ripping and then again when backing up and ripping. When backing up and not ripping the motion and slack in the track between the high drive sprocket and the rear roller the motion and slack in the track going forward when pushing and when backing up when not ripping. However when backing up when ripping the track between the high drive sprocket and the rear roller becomes as tight as the preverbal banjo string. I would think this would have to cause some sort of problem with the drive units over time and possibly accelerate track chain wear/stretch among other things. I have no poof that my hypothesis is correct or incorrect just a gut feeling based on what I am seeing. Have a good day and a better tomorrow.

      Yes agree,
      I think those cat designers will be looking at this if they are not already. Anything that increases the productivity of a dozer up from its nominal 50% is on
      a winner provided it does not wear itself out in half the time.

      But how about a dozer kitted out to rip forwards and in reverse then its 100% untilised. Obviosly it cant doze both ways as nothing calls for that so that utilisations stuck at 50%.

    If you look carefully you can see where the D11 is lifting the rear wheels off the ground when pushing the 657's. It's not much but it's enough to lose traction. The D11 operator needs to tilt his blade forward to avoid the problem.

      @segomatu7063 Год назад +2

      @@williammain3247 I think the reason is purely economic : "Time is money!" as you know, by proceeding in this way each movement of the Dozer is optimized, in forward gear it pushes the Scraper and in reverse gear it rips up the ground for the next pass, so no unnecessary U-turns.
      This undoubtedly corresponds to a high cadence with close Scrapers rotation, so no dead time for the guy in the Dozer !
      Usually, we see 1 Dozer for the pushing and another one for the ripping, so here again, economy of means thus economy of money !
      But here in France we don't use this method.

      The bigger worry about reverse ripping is that it reverses the stress (push/pull) compared to forward ripping. if they do both with the machine that's a great way to greatly accelerate metal fatigue. Same reason why excavator sticks break in no time if they're sometimes used with the bucket the other way ("pointing away from the machine").

    Am I right in thinking that the ripper is in backwards, as if you want the ripper it is more money an hour? This is how it used to work in the English China Clay works (ECC), if a dozer was hired just to push tips and scrapers it was easier for the dozer that ripping and pushing.

    That D11 should have its ripper around the right way and just be ripping and the 57,s should be push pulling what the hells going on?

      That 11 has got a hard time moving itself

      Ideally it is a 651 job, short haul, minimal grades and a short loading area so no need for twin powers as they just cost more to run, but they may only have 57,s available, the material is rocky so they are treating the job like they would use 51,s by pushloading them, D11 does not have a lot of time between scrapers so reverse ripping a shallow depth to help load the scrapers.
