Well, not knowing much about anything anymore, does this unit have the UPS unit located in some obscure closet in another part of the building no doubt, to bump the car up to floor level? Seems there has to be some way to move that car in emergency situations outside the hoistway. Maybe instructions pasted inside where the drive is?
I hated the MRL too, for reasons like this.
Hopefully someone green or with better knowledge than myself will post up for you.
