TENSIONING SYSTEM FOR THE TRACTION BELT OF AN ELEVATOR, AND AN ELEVATOR

摘要

The tensioning system (180) for the traction belt (160) of an elevator (10) is installed or can be installed in connection with the car (100) and/or the counterweight (110) of the elevator for pretensioning at least one traction belt (160) running between these and comprises means (219, 181) for storing energy. In addition to this, the tensioning system (180) is configured to use the energy stored in the means (219, 181) intended for storing energy for pulling in the traction belt (160) in question for returning tension when the tension of the traction belt (160) falls.
