I was wrong about these three companies that would replace the lift. MPEC decided to modernize this lift, as well replace the motor, which turned out to be great! And I noticed that the floor indicator is gone, and directional arrows are used for floor buttons. But still, MPEC perfectly modernized this lift, and now it runs efficiently! There's also another lift (which is Staff Only) that serves Ground and Basement floors, but sadly it wasn't working and abandoned. I think it was an old Axelrod Lift (the name was replaced by KONE in 1990).
Thanks to Jon5432 for original project Cheap generic lift ride MODDED!. Thanks to HJ2127 for the Alarm.
