Abstract

See full text

An elevator installation and method to passively and reliably generate electrical energy while an elevator installation is in operation includes an elevator car, a tension member for supporting and moving the elevator car, and a pulley engaging with the tension member. Piezoelectric elements are applied to or embedded within the tension member. As the tension member is driven to move the elevator car up and down along an elevator hoistway, the tension member also engages with the rotating pulley. Force imparted to the tension member during this engagement with the pulley is transmitted to the piezoelectric elements which consequently generate electrical energy.
