Abstract (en)
An elevator installation having a car (20), a counterweight (6), traction means (8) interconnecting and supporting the car (20) and counterweight (8), a drive unit (12) to drive the traction means (8) and a controller (18) to control and regulate the movement of the drive unit (12) and thereby the movement of the car (20) further includes a load measurement sensor (32) mounted to the car (20) to output a signal (F) representative of the load of the elevator car (20). A processing unit (34) having an input to receive the load measurement sensor signal (F) transmits a first signal (J) from its output indicating that the elevator car (20) has jammed if the load measurement sensor signal (F) deviates outside a predetermined range (F1-F2).
