I work for a large global industrial lift truck manufacture. (A fork lift)
Some of our class 1 and class 2 stand up warehouse product trucks use a very similar in design joy stick.
Over the years we have used many different designs. These things are very fascinating since you are able to control all functions of the lift truck with one hand. Travel; raise lower forks, tilt, side shift, ect.
That’s about all I am allowed to say.
Nice video Dave.
