-The wave of the future brings with it the creation of buildings without machine room, — says Shannon Nell, Manager of International Public Relations Otis Elevator Co.
(«Building Operating Management» from 1 October 2000).
John W. Reynarts the company Reynolds & Reynolds Electronics, Inc. I agree:
— Eight years later, it is clear that this is what happens.
Reynolds Company & Reynolds Electronics, Inc., founded in 1989, is a supplier of systems for emergency retraction lift building industry. About seven years ago, the company’s attention was focused on the market for hydraulic elevators. Reynarts joined the company in January 2001 to the position of Vice President of Sales. In late 2002, he agreed to take the post of president of the company and led its activities in a new direction. Marketing research based on market data controllers elevators, points to the future sales growth traction elevators. The company has gone in this direction, developing new products for the market of the traction elevators.
The transition to environmentally friendly products
In the history of the world has come a historic moment. The world of «greens.» «Green» movement is gaining momentum, and the first of his series are many companies: KONE, Otis, Schindler, ThyssenKrupp and Reynolds & Reynolds. KONE is still supplies its customers hydraulic equipment, but the company believes that the future of low-rise buildings and medium-sized direct drive technology for machine-room and argue that KONE — Lift the first company to introduce the concept of elevator without machine room in the industry. To date, it has installed more than 300,000 systems in these countries.
Otis will start seriously cares about the environment in 1997. In a press release published in the edition of «The Hartford Courant News» August 19, 1997, the company says it will «deliver lifts lt; … gt; for the building of Conde Nast Building at Times Square 4 in New York. , Otis won the contract in part because of its approach to environmental issues, health and safety … «.
— This is the first US installation of high-speed elevators with AC drives with variable speed — said vice-president of Otis’ Ray Monsini. — These drives consume less energy and cleaner than traditional DC drive system.
According to the company Otis, the use of lifts AC drive offers superior indoor air quality. Because of the engine generator is not used carbon brushes, they do not produce coal dust, which can enter the heating, ventilation and air-conditioning.
The technical data SPEC-DATA® Sheet for traction sheave elevator 400A® The Schindler says that the elevator «requires less vertical and horizontal space of the building.» 400A System «consumes 30% less energy than traditional gear model» and «environmentally friendly.»
— The rating system of «green» buildings Green Building Rating System ™ as part of a leadership program in the field of energy saving and environmentally friendly designs (LEED) encourages and accelerates global adoption of the practice of «green» construction with the requirements of the environment, through the creation and implementation of all clear and all the accepted means and performance criteria. LEED program is an independent certification program in the country and the common criterion for the design, construction and operation of high performance «green buildings» — says the Council for the United States Green Building, which includes the company ThyssenKrupp.
Reynolds Company & Reynolds Electronics, Inc. always encouraged manufacturers of complex lifting equipment (OEM) use the back-up battery as a means to release trapped passengers, rather than the more costly and less environmentally friendly solutions based on the diesel generator.
Keeping up with technological development
The construction market suggest that the elevator will be incorporated the ability to prevent cases when passengers are stuck in it because of the failure of the power supply. The last 20 years of contractors elevators offer their customers a hydraulic lift system with battery backup. However, the contractors did not offer systems with battery backup for traction elevators because they did not exist. In 2002, Reynolds & Reynolds began developing systems Traction Powervator®, designed to save people from the traction elevators in emergency situations. By the end of the 90s with the installation of backup battery for traction elevators it was not feasible, because the battery can not provide a large amount of energy needed to use them in large motors AC and DC, including the squirrel cage.
When OEMs began to produce motors with variable voltage and frequency (VVVF), the company Reynolds & Reynolds realized that there was the possibility of developing an emergency rescue system, realizing the advantage of lower energy demand systems VVVF. The difficulty was to establish an emergency system based on the backup battery for the traction sheave elevator, capable of operating in their inherent physical conditions, allowing the system control of the elevator to move the cabin to the nearest floor (upwards or downwards, depending on the weight of the car and counterweight) with speed check mode and open the car door so that passengers are not trapped in an elevator. Reynolds Company & Reynolds got to this device certificate Canadian Standards Association (CSA), and then it was patented.
The first OEMs, who took advantage of this technology is the company KONE — in July 2003, she used her project Transportation Expansion (T-REX), as evidenced by the records of Lerch Bates Inc. T-REX Project has transformed the Denver metro transport system for those who enjoyed the southeast corridor between routes 25 and 225. The draft decision of transport problems of Denver used several types of vehicles, online www.trexproject.com called it «a new generation of transport projects «.
Today, many consultants elevators indicate in their specifications based system backup battery for traction elevators. Most third-party controllers have studied the effect of, purchased, tested the systems with battery backup for its controllers. Some OEMs offer battery backup as an additional function of its traction elevators. It seems that Nell was right. Welcome to the future.
