The object of the invention is a traction sheave elevator and a rope () that contains metal as a load-bearing material, such as the suspension rope of an elevator, which rope comprises at least one or more strands () laid from metal wires () and which rope () is lubricated with a lubricant (). Another object is the use of the aforementioned lubricant for lubricating the rope (). The lubricant () comprises at least oil and thickener, which thickener in the lubricant () comprises at least 10% or more of the mass of the lubricant ().

In the invention a method is presented for ensuring operating safety in an elevator system, an elevator system, and a safety device of an elevator system. The elevator system includes at least an elevator car, elevator ropes, an elevator motor, a traction sheave and at least two holding brakes, which holding brakes are arranged to prevent movement of the elevator car when the elevator is stopped. According to the invention the first holding brake is engaged at the end of an elevator run, and the other holding brakes are engaged with a delay. When one holding brake is engaged, the state of motion of the elevator and any slipping of the brake is monitored. If the brake is detected as slipping, a procedure for preventing a hazardous situation is performed.
