    • An elevator, preferably an elevator without counterweight, which has an elevator car suspended by means of a set of hoisting ropes comprising one rope or a plurality of parallel ropes. The elevator has a traction sheave that moves the elevator car by means of the hoisting ropes. The elevator contains rope portions of hoisting ropes going upwards and downwards from the elevator car, and it has a compensating device acting on the hoisting ropes to equalize and/or compensate rope tension and/or rope elongation. The compensating device acting on the hoisting ropes of the elevator, said compensating device having at least a first range which is a structural operating range of the compensating device and at least a second range which is a preselected compensation range of the compensating device, is provided with at least one switching element for monitoring whether the compensating device remains within the preselected compensation range.

    • An arrangement for equalizing rope force of an elevator may include: a hoisting machine, set of hoisting ropes, traction sheave, elevator car, guide rails, and compensating device. The hoisting machine may engage the hoisting ropes via the traction sheave. The elevator car may be at least partially supported by the hoisting ropes to move the elevator car. The elevator car may move along the guide rails. The compensating device may include first and second tensioning devices. The first tensioning device may be spaced apart from the second tensioning device. The first and second tensioning devices may be interconnected via a transmission device that transmits rotary motion. A first end of the set of hoisting ropes may be secured to a point in conjunction with the first tensioning device. A second end of the set of hoisting ropes may be secured to a point in conjunction with the second tensioning device.
