Parking garages use something similar, but to my eye more dangerous, to get the staff quickly to different floors. I have no idea what they are called.

- Animats 11y agoManlifts.[1] Those are more dangerous than a paternoster. They're essentially a powered ladder. The biggest hazard is failing to get off at the top, because the belt just goes over a pulley and back down, which would throw the rider down the shaft head first. OSHA: At the top floor an illuminated sign shall be displayed bearing the following wording: "TOP FLOOR - GET OFF" ... a red warning light of not less than 40-watt rating shall be provided immediately below the upper landing terminal and so located as to shine in the passenger's face. ... Two separate automatic stop devices shall be provided to cut off the power and apply the brake when a loaded step passes the upper terminal landing."
