Claim:
1. An elevator comprising: a car; a counterweight; a rotatable drive member; one or more suspension ropes interconnecting the car and the counterweight and passing over the rotatable drive member; a drive machinery for controlling rotation of the drive member; a sensor mounted on the counterweight and arranged to sense a state of an elevator component, a hitch plate connected to the one or more suspension ropes; and at least one spring mounted to said hitch plate and a counterweight frame, such that the at least spring is located between the hitch plate and the counterweight frame, wherein each of said one or more suspension ropes comprise at least one electrically conducting member extending continuously along the length of the rope forming an electrically conducting connection between the car and counterweight, wherein the sensor is functionally connected with the drive machinery via said electrically conducting connection between the car and counterweight such that a predetermined state change sensed by the sensor triggers the drive machinery to brake rotation of the drive member and/or to stop rotating the drive member, and wherein the sensor is provided adjacent to the hitch plate.
