Abstract: A counterweight and an elevator car are suspended on a set of hoisting ropes, the hoisting ropes being steel wire ropes or having a load-bearing part twisted from steel wires. The elevator comprises one or more rope pulleys provided with rope grooves, one of said pulleys being a traction sheave driven by a drive machine and moving the set of hoisting ropes. At least one of the rope pulleys is provided with a coating bonded to the rope pulley and containing the rope grooves, said coating having a thickness that, at the bottom of the rope groove, is substantially less than half the thickness of the rope running in the rope groove and a hardness less than about 100 shoreA and greater than about 60 shoreA. In a preferred solution, the traction sheave is a rope pulley like this.

Abstract: In an elevator, which preferably is an elevator without machine room, a hoisting machine engages via a traction sheave a set of hoisting ropes comprising hoisting ropes of substantially circular cross-section. The ropes have a load-bearing part twisted from steel wires of circular cross-section and/or steel wires of non-circular cross-section. The average of the wire thicknesses of the steel wires of the hoisting ropes is less than about 0.5 mm and the wires have a strength exceeding about 2000 N/mm .

Abstract: 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 comprises 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 (106,107) is engaged after elevator run has ended, and the other holding brakes (106,107) are engaged with a delay. When one holding brake is engaged when the elevator is stopped and empty, motor torque is increased to a certain limit and the state of motion of the elevator and any slipping of the brake is monitored. If the brake is detected as slipping, the torque at which slipping starts is registered and a procedure for preventing a hazardous situation is performed.
