You had to call in an engineer for that?
I failed to see " massive rock slide "
Holy crap that’s a ghetto outfit moving trailing cable by hand underneath a live digger? Wow love to see this happen at Mt Arthur 🤣🤣🤣
That must be a cheapskate outfit. Swapping one tooth at a time is a "money saving" move, that ends up costing more money in the long run. Pulling all the teeth at regular intervals and swapping them with new or rebuilt ones is more efficient in the long run.
i dont think they changed one tooth i think they just didnt show them changing all of them after watching them do one we get the point
@@alhagopian2100 I will say potato
Hello
Agreed. Teeth are a normal wear item.
Outside ones ware quicker so they swap them to the inside and new ones go to outside.
There's a wheel dozer there, why don't they have used that rubber tire to pull the trail cable while the d10 pushed the pole bridges?
真是个大家伙👍🏻
It's a face shovel, it creates rock slides !!
Claw is not such a bad ass when you shut off the electric. 💤
Great big Excavator RH 400 0&K Orenstein & Koppel 🇩🇪👌👍💪
Could anyone understand what the manager was saying?
Should have bought a diesel shovel and not electric.
A diesel shovel needs way more repairs than a electric shovel, remember the diesel is an engine with all its moving parts on and in it. Also the costs for diesel will be way higher then electric, heck with a bit of thinking they can produce theyr own energy and if they done that, the electricity is for free.
Electric is better as CRTukker pointed out. I still don't like the thought of barehanded man-handeling thoes 6Kv live wires though (they'd have to be live right? Surely you can't move it without the main power supply). I'd like to think it's armored wire and has a surrounding grounded layer of copper sheathing to divert faults away from people and trip some sort of breaker incase the cable gets nicked on a sharp rock. Even then I'd be tempted to spend the $50 and get some certified insulating gloves.
@@charmio see the issue is would you save in fuel you lose in having to have 24-hour available man power and not a small crew at that, for every time it has to remotely move. With a diesel power plant you will still get the same performance greater movement and less people in the line of fire.
steveMCHS the electric version seems like more hassle to me. At the end of the day there’s still a diesel generator powering it. And then the hassle of moving the wires and so on. Maintenance is no hassle when you do it right.

No brake fluid and no transmission oil in a Terex RH400.
Well depends how you look at it
Yeah its Hydrualicly Driven like all excavators and face shovels.
Brake fluid? In a hydraulic excavator?
Autos.com has this to say about the difference between the two:
"There are many uses for hydraulic oil, and hydraulic brake fluid is just one variant. Hydraulic brake fluid is made of refined mineral oil or water depending on the brand you have used. It is basically a special form of hydraulic oil that is used specially for braking. These materials have a high boiling point that makes for a perfect braking fluid. These qualities are needed, as there is a large amount of heat produced during braking. Prolonged braking over long distances would cause the brake fluid to evaporate, but this does not happen."
Jim Watson (Mechanical Engineer 1988), goes into MUCH more detail and although talking about steering fluid still hits on relevant points:
"No it is not there is a big difference within the two if you put brake fluid in a typical power steering application it may work but I guarantee you that it won't last long ,the brake fluid is not meant to be used in a continual high pressure hydraulic pump and does not have the viscosity requirement to be compatible in the mechanical pump driven power steering environment plus there are other requirements that brake fluid simply does not have to survive a power steering environment a very big disadvantage that you will notice first is after all the rubber seals swell up in the power steering environment they will then start to either harden up or and most likely will start to breakdown and deteriorate and start leaking anywhere there is a rubber seal along with contaminating the complete system and clogging the system and symptoms will include chatter steer as the pressure reverse valve that is responsible for the line pressure to switch directions when turning the steering wheel from left to right the oriface that the fluid passes through usually has a “check ball” that will close one passage and open the other one directing the pumped pressurized fluid to assist the steering box to help ease the amount of strength needed to turn the steering wheel the contaminated valve will restrict the amount of pressurized fluid that can make it to the steering box causing the chatter along with that and the fluid leaking everywhere the return line and side of the pump will be equally contaminated with the debris from the breaking down rubber seals and there is a mesh wire screen within the system to collect any debris before it can get into the actual pump and cause catastrophic failure of the pump .clogging that mesh screen and other points and orifices within the system will cause the pump to starve /cavitate and that will also kill the pump back way early when power steering was first introduced on a broad spectrum if transportation the rubber seals within the power steering pump were more prone to leak as technology was behind that of the mechanical pumps service life and an old trick was to add just a minute amount of brake fluid to power steering fluid in the pump and that mixture would swell the seals up enough to stop fluid leaks giving more life before service had to be done and the same was true for automatic transmissions but there also it was just a bandaid that would hopefully buy some time before a major service had to be performed .if it is an emergency and there is no power steering fluid available the best alternative would be to use automatic transmission fluid as it is the most comparable to power steering fluid in that both systems the hydraulics of the automatic transmission fundamentally work in close proximity as that of a power steering environment a high pressure high speed hydraulic pump gravity /low suction building positive pressure of fluid that must pass through small cavities and through various pressure valves ( a valve that is usually a ball bearing located in a cavity/passage with a spring on one side of the ball bearing that stops with the ending of the passage it resides in and a small orifice behind the ball bearing so that when the hydraulic pressure from the pump overtakes the resistance of the spring behind the ball bearing the bearing will be pushed back exposing the opening of the passage and the fluid will pass through and operate a diaphragm type valve or help pressurized a galley that helps to assist the direction of the steering box or in the automatic transmission it will pressurized a mechanical gear selection or operations of the automatic transmission so the environment between the two systems is that of more symilarity than the braking system and more compatable."
@@charmio I have operated many excavators and I have not seen one that the operator's manual specified brake fluid.
@@charmio wow all those words to say nothing.
@@wailnshred I'm with you on that one.
@@charmio You're a peanut mate, Brake fluid is a similar oil to standard hydraulic oil, but its not the same. Excavators do not have power steering, transmissions or brakes, there is a giant spring-encased cylinder usually in the front of the track frame that presses on the idler.
As you push on the travel sticks/pedals this sends a message to the control valve to draw on the pump, an electrical signal is also given by the computer to increase power at the engine away from idle.
The engine has a shaft which drives the pump (Mechanical).
The pump converts this mechanical energy into hydraulic flow, the system provides the resistance which against the flow from pump provides the pressure.
The pump sends hydraulic fluid through the control valve and down the swing ring, through (or on/under) the undercarriage, to the track frame and then the final drives on the sprockets.
No transmission, its an 'hydraulic excavator', the engine powers the pump or pumps, the pump and the alternator is doing everything.
The swing motor is electric but it is run off the pump not the 24v electric system.
You’d think people would make a better system for that cable so it won’t be run over.
I wanna be excavator driver so bad but unfortunately there's nowhere to start.
Here’s what you need to do to get an excavator like me
1.save up money for some sort of animal big enough to harvest crops
2.save up for farming equipment for that animaL
3.farm for about months or years
4.once you are done with farming and have enough money go buy an excavator
And there you go
Cash crop weed
The ohne guy is very useless😂 He does nothing But is tired
Rocks failing. It's part of the job. Get back to work. And load those truck to their max.
Your teeth are fine baby. Don't listen to the producers. They show footage of your old teeth, after your replacement.
