The elevator man that was injured that got me thinking about the TOJ was hurt when a car ran with the car top stop switch had been jumped!!! Like I said the hall and car gate are the big attension getter but may not be the leading cause of people getting hurt. Killed maybe but hurt ???? Yes the TOJ are priced at around 90$ so 3 per man 270$ alot cheaper that even 200$ for every elevator. JKH the max time is 99hrs and 59 sec. But there is a master controll that can be set to only allow an predetermined amount of time. Say 10 miniutes if that is what a company decides to set their safety policy to.
