Someone sent a link to this to me today.

Pretty nice, actually generates it's own electricity to power itself!

Of course the real energy input is in breaking and loading the rock, but still pretty impressive!

What an absolutely stunning piece of kit. I guess the same process could also power an incline/winder........... IP: 95.145.102.92

Yeah, love it!

I think the fact it uses more power than it generates is a PR stunt, I mean when it gets back to the quarry they have a surplus of 10kwh which I think is about 50p in commercial electricity rates. do they actually bother connecting it up to drain the surplus for that? Or keep the juice it in the battery "just in case"? I'll bet its the latter. I think they like to say its possible to feed power back but I'd be amazing if they actually bother.

Nice to see innovation of this kind though. A proper EV.

10KWH*20 trips per day = 200KWH....They might go two days and transfer 400KWH worth in one go, that would still leave 300KWH in reserve.

Whilst it is easy to get enthused about these electrical vehicles, there are lots of problems, some of which are hinted at in the piece.
Large Lithium batteries are going to used for storage in south Australia, but have all the 'fire risks', been sorted out?
Then there is the problem of recycling these batteries, when they have reached the end of their life.
Governments are committed to phasing out the internal combustion engine, but could the transmission system cope?
I think there is a great future here but it will have to be taken steadily and slowly.

When you think about it they have to get rid of the surplus energy from regenerative braking somewhere. If you just keep putting it into a now fully charged battery you soon end up with a very expensive wrecked battery, so putting it back into the supply is the best option, even if financial benefit is minimal.

Makes my ebike look a little tame.

That though has now covered 2000 miles since I bought it just after Christmas, pretty much solely commuting to work. My fairly crude calculations indicate that it has now more than paid for itself in vehicle running cost savings Smile

Rather looks like re-inventing the wheel to me. We were achieving the same end result over 100 years ago simply by using aerial ropeways! Loaded buckets descending the rope haul empties back up to the top in a continuous loop. No need for haul roads, embankments, cuttings, bridges etc. Just pylons spaced 100 yards or so apart and a wayleave payment to the land owner. Very low tech compared with this truck but does the job without any fuss and without the expense of batteries.

Indeed Roy. I've always had a liking for ropeways. Claughton near Lancaster is the last operating one in the UK. Sorry to go of topic - nice shiny dumper by the way! Reminds me of Tonka Toys.
One thing I did notice; if it is electric why does it have a radiator grill?

Guess it still has hydraulics and aircon etc which still need cooling. The electric gubbins probably gets quite hot too so may even have a water cooling system. My son's PC at home has a water cooling system complete with rad, fan and water pump but that is just a gimmicky fad designed to sell expensive "gaming" PCs to 17 year old lads!

Also its a conversion from a standard internal combustion engined design which needed the big radiator.

Yes, I see your point. Start with a standard truck and modify it accordingly.

Back on the subject of aerial ropeways, wasn't there one over the railway line near Mexborough...Denaby Main?.
It was operating in the early seventies.
