I do bieleve that most of the manufactures of tier 1 and now tier 2 forklifts have a speed reduction system.
I suggest, that if speed is a major concern, those of concern contact the manufacture for a solution.
I am aware of a company based in TX that offers an aftermarket solution to speed control, plug braking on IC trucks and speed limiting. If you would have interest contact me, my email is posted in my profile, and I will assist you.
