“You cannot run diggers with electricity.” someone replied to a post on EVs saying the application of battery electric vehicles is limited. Well here you go - this is the biggest all electric digger in the world. https://lnkd.in/e6wwCrFY “[…]the Komatsu PC8000-11 […] will operate solely on electricity.” “Electric excavators and other equipment contribute to the mine’s electric ecosystem. The PC8000-11 electric excavators operate in the mine’s loading station, powered by a nearby substation.” https://lnkd.in/eerTD8sa

Reading some of the comments here is like watching people argue that 2+2=7 and have zero concept of the energy used by a PC8000 loading shovel, let alone the energy requirements of even a mid-size dragline. The PC8000 in this original post can be operated by diesel or by electricity and yes electric is much more efficient and cost effective. That electricity however comes in at 7KV via a trail cable attached to the power grid, not from a battery. Anything much larger than a PC8000 MUST be electric. A mid size dragline like a 1570 or 8200 pulls around 15MW at peak power, then regenerates 2-3MW back on the line, approximately every 60 seconds. These are sometimes fed with 7KV but more often with 25KV, always from a power plant, not from a battery or solar farm. Electric power and battery power are not interchangeable terms. "Green Energy?" Yes, I'm all for it wherever it makes sense, but trying to spread nonsense of what it can and cannot do is either clueless ignorance or simply dishonest.

Impressive 800 t machine 75 t 42m3 payload for the bucket, 3 MW or 4,000 HP. I guess they are connected on the grid. But cable needs not to be more that 1.5 MW power. If you remove the two diesel engines, you might avoid 10 tonnes which could be replaced by batteries. With 200 Wh/kg, then you can have 2 MWh of storage. Which allows you to have surge power at 3 MW very easily. Has anyone more info about that?
The biggest diggers are called draglines and have been running on electricity only for well over 100 years, they run off high voltage 6 to 22kVa power grids. Assuming this excavator is all battery powered the main advantage is that this can be moved like any diesel powered excavator.
It was an act of genius by Volvo to get a Lego set made of their own battery-electric digger https://www.lego.com/en-gb/product/volvo-fmx-truck-ec230-electric-excavator-42175 -- now millions of people like me, who have no connection to the civil engineering industry at all, know that there is such a thing as an electric digger.
Amazing how many people in the comments don’t want this to be true.
Try again! The Komatsu PC8000-11 hydraulic excavator has a fuel tank capacity of 13,925 liters (3,679 U.S. gallons). It also has the following engine specifications: https://www.smsequipment.com/en-us/new-equipment/excavators/komatsu-pc8000-11/
Is that a full electric (powered by DC cable) or a diesel-electric?

4wJan Rosenow - from the comments it appears it might be worthwhile adding this to the post: “[…]the Komatsu PC8000-11 […] will operate solely on electricity.” “Electric excavators and other equipment contribute to the mine’s electric ecosystem.
