Heritage Elevators published this interesting video of an antique elevator in motion in 2011, but it is trending again now. The chain-driven Paternoster elevator by Titan was made way back in 1913 in Copenhagen, Denmark. The elevator is in a constant state of motion with one side moving up and another moving down, similar in concept to an escalator. Riders must quickly and careful enter and exit the elevator as the cab is always moving. It is quite apparent why this model of elevator is no longer used.
