ThyssenKrupp TWIN庐 elevator system introduce elevators that save time and space. With the continuing construction boom in India, buildings are getting taller and owners are placing greater demands on their elevators to provide increasing passenger transportation capacity. In this context, the TWIN庐 elevator system, exclusively supplied by ThyssenKrupp Elevator, can save time and space. It is the only elevator system in the market that has two cars moving independently in one shaft and addresses a range of issues that owners, operators and occupants of tall buildings face daily. Minimum waiting and travel time Because two cars operate independently in the same shaft, TWIN is able to take two passengers to two different floors simultaneously. Unlike a double-deck elevator, passengers no longer need to make 'false stops' while passengers in the deck above or below enter or exit the car. To reduce the travel time, TWIN exploits the advantages of a passenger grouping system; ThyssenKrupp Elevator's intelligent destination-selection control (DSC) system minimises travel time by reducing the number of stops each elevator makes. At the boarding floor, passengers indicate their destination floor on a touch screen terminal. The computer assisted system then determines which elevator will arrive fastest and displays it onscreen. In addition to optimising traffic flow, the DSC system makes elevator group operation more flexible and can be adapted according to the occupants' requirements, including VIP or emergency call overrides for immediate access to an elevator. Increased floor space and passenger handling capacity Traditionally, improving the service level of an elevator system means a loss of rentable space due to a larger elevator core. TWIN provides building owners the choice of better traffic handling capacity without increasing the footprint of the elevator core, or the same handling capacity as a conventional elevator system but with a smaller core. Furthermore, an unexpected design benefit of TWIN is the visual impact its panoramic car option can bring to a building exterior or atrium. In addition to maximising passenger handling capacity for new buildings, TWIN can be retrofitted as a modernisation option to increase the traffic handling capacity of the existing elevator shafts by boosting the system's capacity. Energy savings TWIN elevators are powered by energy efficient gearless machines and equipped with regenerative drives that feed energy produced by the motor during the generative mode back into the building's power supply system. TWIN offers an additional 30 per cent energy savings compared to non-shuttle double-deck solutions,since double-deck elevators have a heavier total mass to move, whereas TWIN needs 30 per cent less connected electrical loads, which means smaller ratings for transformers and electrical wiring. Another advantage of TWIN over double-deck systems is the capability to downsize the building's emergency diesel generator by 50 per cent. Furthermore, the TWIN system offers the ability to park and switch off one of the cars when traffic is light, thus saving additional energy that significantly contributes to lower operating costs over the course of the building's life. Safety and reliability ThyssenKrupp Elevator has developed an innovative quadruple-redundancy safety system facilitated by DSC 没 namely, anti-collision routing, automatic monitoring of minimum safety distances, an emergency stop function and automatic engagement of the safety gear, which all work together to keep the two cabs a safe distance apart at all times. In compliance with the International Electrotechnical Commission's EN 61508, these last two safety levels are continuously monitored by an independent control system, giving TWIN Safety Integrity Level 3, the highest possible international safety classification. By now, close to 200 TWIN systems have been installed in new and modernised buildings around the world. (Communication by the management of the company)
