I agree with Ben. The bigger you go the smaller the potential worldwide market you have to sell to. I know a number of years ago Cat looked at making something larger than the 994 and when they analyzed the potential market for such a size of machine the sales numbers were so small that it would have taken them literally decades to recoup the development costs so the idea went no further. I would think a big brother for the 797 would fall into the same category.

In my experience Cat should have stopped with the 992 and not gone any bigger. At a minesite at present where 4 994Fs are operating and they seem to frequent the workshop regularly. Also running 2 Komatsu WA1200s and 2 LW1850s.

The only reason for a 994 to visit a workshop regularly is poor maintenance or neglect IMHO. Too many people treat it as an overgrown 992, it's not. It's a mining machine and has to be maintained like one. The Maintenance Dept has to be all over it like a rash all the time. I've seen neglected 994's give availability of less than 50%, well-maintained ones over 90%. The highest hour machines I was involved with had over 70k hours on the clock and were still meeting an 85% availability target day-in, day-out. Currently we have 3 F's with 20k hours on them where availability is around 85-90%. That will reduce somewhat as we go into planned component changes in the near future.
Apologies for taking the thread off track. We were talking about 500-ton trucks.

We don't have any thing that big but seems like too many bosses think with a typo in their head. They think "Preventive Maintenance" means "Preventing Maintenance"

Good one. I'm going to remember that one and wheel it out at opportune moments .........They think "Preventive Maintenance" means "Preventing Maintenance"
I found this video while browsing.
Looks like the chinese copy of the ETF truck has beat the original to the field.

Yair . . . Good one JDOFMEMI .
To my untrained eye it looks quite impressive. It certainly appears quite responsive and doesn't hang about.
Cheers.

It seems to have a pretty fast take off loaded(unless they sped the camera up) it will be interesting to see the development of this concept
If you look closely, the video gets sped up right as the truck pulls away from the shovel, in order to make the truck look faster than it really is.
One of the tells of this is if you watch the shovel dipper in the background, you see it cycle at nearly twice its normal speed it was moving while loading the truck. I think the truck is a slug, but marketing doesn't want anyone to see that. It looked slower that normal trucks while running loaded, once you figure out the video is running double time.
I guess time will tell if it is a success or not.

Been a long while but I've kept my eye on the ETF truck comcept, but how many tons capacity is the Chinese version? Note, to my untrained eye, the Chinese version seems to have a large load bearing structure between the dump bed and the running gear.
Anyone heard anything new about newer huge trucks? How many of that monster 500 ton capacity Belaz one in Russia have been built?
I figured attacks on the coal industry by the Obama admin. and the drop in oil prices have reduced the impetus to build larger ones by Caterpillar and other manufacturers for coal mining and tar sands

The way mining markets are right now manufacturers are looking to save money not spend it. There is no stomach for anything larger than what's currently in service.
Regarding the larege Belaz there were a few clips posted to YouTube when the model first went into operation (you can tell it was because in every clip the truck is clean and shiny) but nothing since. Every clip posted more recently than the first one is obviously the same truck video'd on the same day, just uploaded to YouTube at a different date. It's more than likely been consigned to the scrapheap of history along with the other efforts from the same manufacturer.

I don't know. The Russians never seem to like throwing away anything.

You've obviously never worked in Russia I take it..? Maybe I need to scan some of the photos I have of the scrapyards at the mines in Siberia I was at ....... what looked like almost new machines all with unpronouncable manufacturer's names just dumped in lines.
