Makes sense. It doesn’t travel far from the charger and massive battery weight isn’t a problem since it only operates off-road.

The weight reduction just from not having engine oil and fuel is significant.

A Komatsu 960E carries about 5 tons of fuel (1400 gallons) and nearly half a ton of oil and lubricants.

How much do the batteries in this one weigh, and does it run for the same length of time? 5tons isn't that much compared to the total weight it hauls

Yes, not needing to roll out charging infrastructure across the world (or agree one standard) make this much easier than cars.

diesel to hydrogen engine conversion covers the aspect of having no electricity infrastructure close. Also negates charging downtime. JCB make lots already.

These trucks tend to run basically 24/7 though. It's not like they run them for 8 hours and close down for the night.

It's a cool idea but it seems like it's not really going to work. The reason they have trucks so massive is to increase throughput, without buying more trucks.

I'm not sure they'd want to buy extra trucks to sit idle.

I feel like figuring out some sort of easy way to run them off of electrified tracks would make more sense.

Depending on where they’re used, they might not need to be charged at all. Like if they load cargo up on a mountain and then drive down. They can charge through regenerative braking. On the way up they’re empty an use less energy.

Human drivers need breaks and these might be enough to charge the trucks.

Building a train is also an alternative commonly used in mining.
