    My hope is that by getting feedback from real users, the report will reflect reality.

    Thank you, I didn't know about the Case and Komatsu trials. The Case website is very helpful. Thanks for your feedback.

    You need a machine that can run at 85 percent of capacity for 10hours aday to be able to market it anything less and it will fall short of demands and a few bad experiences will taint the program for years

    I myself wouldn't even look at a machine for battery unless it came to that criteria

    Awkward Potato,
    Not looking to offend you but.... You seem to want input from folk that are in the trenches that will prove your point. No one wants to disprove your attempt to come up with a better source of power; Most of us guys in the trenches HATE to see waste. Most of us are thankful for the natural beauty and resources we have enjoyed and want them to be managed so future generations can share that same experience and support anybody that can come up with REAL solutions for other more sustainable energy sources. But we have also seen crap like ethanol jammed up our hind parts (engines designed to run on 10% do ok, engines not designed for it just pass it though, and "flex fuel" engines that are required in many states are not able to run efficiently on ether gas, 10%, or 85%) and diesel "after treatment" systems that have been a enormous increase in operation cost (including additional fuel) with very questionable positive results. So please don't be personally be offended if some of us are not wanting to get battery powered HEAVY EQUIPTMENT.
    On the bright side I no longer fire up the big compressor to knock of a few bolts, instead I grab my battery powered inpact!
    Keep the faith brother, I hope you come up with something REAL for all of our sakes.

    Thanks Potato for trying to get some input from real users like you suspected %50 usage is low and can vary so much from day to day
    All equipment built in say the last 20 years have computers that track idle time ect and with all the telemetrics all the manufactures know what the real world usage is

    @crane operator that hybrid does look good for most crane work. that's a case where the idles does amount to a significant portion of fuel.

    63 Caveman brought up some good points. This subject of battery operated equipment has been studied to death. I remember being a struggling University undergrad in 1990 addressing the same questions Awkward Potato is asking 30 years later. The market did what markets do.

    The market provided us wonderful battery operated aerial lifts, lift trucks, underground mining equipment, and whatever else that makes economic sense

    Admittedly, I’ve never done original research. When I finished my graduate work, I opted for a M.Ed. I took an 8 hour comprehensive exam instead of doing a research paper. That doesn’t mean I don’t understand the process of original research.

    awkward hasn’t demonstrated any sort of research Protocol. The OP hasn’t introduced themselves or their pronouns, the institution, the study, and all the other disclosures and permissions required to gather research data. I don’t understand what the angle is.

    Flame me if you want, I spent half my career in Higher Ed. I understand how the academic research biz works.

    Hi Caveman,
    No offense taken. I don't have a dog in the fight (not being paid to work on the project), I'm just trying to make the project better by getting input from real users. Electric equipment has some great advantages, but a lightweight and long-lasting fuel source is not one of them. My goal here is to make sure the results of the study reflect reality, so that the readers/decision makers are informed and recognize where batteries are viable and where they are not. If the reality is that battery can only replace diesel in a few special situations, the report should say that rather than claim most equipment can be converted to battery.

    Thanks Coaldust,
    To clarify, I am not part of the research team, am not representing an institution, and am not gathering data for research purposes. I was asked to provide feedback on a study, and it seemed important to run assumptions by real-world users to help make sure the research reflects reality. You are correct that if I were part of the research team I would go through official routes and pay folks for their feedback. I am grateful to everyone here who has contributed.

    When speaking of HE while looking at say a D8 high track
    Weight in excess of 35 ton
    Need to be able to move the base mass then the product being cut away

    HP is HIGH to move all that need be moved so energy use as in hp vs work performed will also have to be High requires a load of battery energy regardless gear reduction.
