For the record have been retired since 2007. Never spent one day or even a half of day working directly and/or as a consultant for/to Hyster/Yale, Nacco or what ever they are called now. But I did and do know people that worked for Hyster/NACCO. Guarantee you we don't talk about zero emission anythings.
Did work for the following lift truck companies
1. Allis Chalmers - my first 14 years in the lift truck ball game right out of college - did know the late Sir Neville Bowman Shaw - the self proclaimed side loader king in the UK - aka Neville the Devil and his younger brother Trevor
2. KD Manitou for 2.5 years
3. Mitsubishi in Houston, TX - 12+ years
4. Komatsu Forklfit - Covington, GA - 5+ years
5. Before retirement I worked for an independent Clark dealers for 5 years.
You can take the above info to the bank but..............your first ASSUMPTIONS in the first sentence are definitely off base. Because of this, I didn't read past the first sentence of your rather l rant as you don't even believe what your wrote. See in your very first sentence you started out saying WE (you and that mouse in your pocket I guess) ESTABLISHED (have found solid/strong evidence to back up your Scientific Wild *** Guess or SWAG for short), then when you expanded on your second finding by using the word PROBABLY (which means "maybe yes, maybe no" or is solid information equivalent to "trying to eat a soup sandwich" or it is just "wishee washee").
Sorry bucko
