Abstract:
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.
