20110017551 | Elevator - An elevator may include an elevator car, a set of hoisting ropes, a traction sheave, and a compensating device. The set of hoisting ropes may include first and second rope portions. The elevator car may include one or more first diverting pulleys from which the first rope portions extend upward. The elevator car may include one or more second diverting pulleys from which the second rope portions extend downward. The first rope portions may be under a first rope tension. The second rope portions may be under a second rope tension that is different from the first rope tension. The compensating device may act in substantially opposite directions on the first and second rope portions. The compensating device may produce an auxiliary force acting substantially in a same direction as the first rope tension. | 01-27-2011 |
20110220455 | PEOPLE MOVER, TRANSMISSION CHAIN AND METHOD IN THE USE OF A PEOPLE MOVER - A people mover comprising a plurality of steps or palettes to carry and move people.
