I know of a forklift that's pushing 80 and still used in a lumber yard (i.e. a material handling centric workplace)
Other than ~30min it takes to teach an employee to drive manual it doesn't do anything worse than the modern ones it works alongside and it does a handful of minor things much better by virtue of predating OSHA.
What does it do better by predating OSHA? Are there liability concerns or does it have just enough safety to be insured economically?
