[Focault's Pendulum]

Your point's 100% valid except for one small correction: a fully charged battery in an electric forklift can lift as much as a propane forklift. The battery adds an awful lot of weight to the vehicle. The problem of electric vs. propane is actual run-time, that's where propane excels.

I don't disagree with you, but the old electrics could only do a twenty foot lift at weight to 20 feet height 1 0r 2 time before recharging..

It's been a long time (30 years...) so I don't remember the make/model of the electric forklifts I drove, however I do remember them being more capable than that. Granted, I was only lifting pallets of paper cups. Boxes were only about 30 lbs each. I stacked enough of 'em back in the day so I remember that. Trying really hard to remember here, I think the max a pallet could hold was 20-24 boxes so the weight was under 750lbs + the pallet (another 15-20.) Not much even for an electric forklift.

But you're right: the real heavy loads would drain the battery after only a few lifts, that's what the Propane lifts were for. We had propane powered clamp trucks that would pick up 4,500+ pound rolls of paper and either stack them 6 high or put them on the line to make the cups. Those were MASSIVE machines.
