Steel - a material offering potential for enhanced performance and energy efficiency - FURTHER DEVELOPMENT OF PROVEN SUSPENSION MEANS IN ELEVATOR CONSTRUCTION

摘要

Energy efficiency, ecological efficiency, environmental compatibility-all issues which, as in countless other sectors, have become an established aspect of the elevator industry. While only a few years ago, increased speeds and higher elevators at the lowest possible prices were generally at the forefront of development objectives, today research tends to be driven by the achievement of greater economy and sparing use of resources. The design of the first machine roomless elevator in 1996 sparked a move towards ever smaller and more efficient drive systems which questioned existing concepts and consequently marked a departure into a number of new directions. Even counterweights have become surplus to requirements - a development which nobody would ever have envisaged only a few years ago.
