9000kW sounds about right, it weighs 5600 tons. So if you converted that to a decent size car, of 1.4 tons (1/4000 the weight) it would have an engine of 2.25kW, and move at barely a walking pace. The video is sped up a fair bit, they gently undulate across the landscape as opposed to looking like Howl's Moving Castle.

That's not a whole lot of power for an industrial system. But that's still a pretty significant trailing cable application. Wish I had a single-line diagram of the high voltage systems for that machine. Also that led me to look up some stuff and I found this useful information about shock safety with mining cables.

I guess that's why they had a tracked vehicle to drag it around, but that cable didn't seem anywhere big enough.

Megabound posted:Those are spots where the tire wall has thinned and weakened, I think. They don't thin and weaken, it's only impact that does that. Tears the outer layer away from the inner layer so that air pressure can get in between them and bulge out like that. If you have one of those on your tire you need to replace it.

Machine isn't producing anything, just jacking itself across the countryside - the draw will be significantly less than when it's chewing up overburden. Soon the parasitic tyrespiders will hatch to begin the cycle anew. IPCRESS fucked around with this message at 13:38 on May 20, 2017 |

This is what happens when you fill your tires with nerve gas instead of air. Just use air, it's way easier to get and it's everywhere. I don't know why you have to make it so complicated.

Fanelien posted:It's actually not uncommon for mining equipment to move like this. It removes the need for an expensive axle and differential arrangement to take the massive weight, and it never bogs in the soft ground of the mine. My local machinery club has a small dragline with a similar but different movement method. At first I was like "good lord, if someone gets a toe trapped under that their foot is going to be squished into a fine paste." Then I thought about it for a bit and looked up the weight (3840 tons) and estimated the diameter of the base (100 feet) and turns out it's only about 67 psi, which is not bad at all. Less ground pressure than a bicycle tire.

How would you even deal with a situation like that? Try to sneakily let the air out without getting your arm blasted? I wouldn't recommend poking it with a sharp stick or throwing rocks at it.

If it's this type of tire gauge:  Then the little nub opposite the part you take the pressure with is meant to let you open the valve and let out air (if it has one, not all the pencil gauges have them).
