Method for installing an elevator, and elevator

An elevator, comprising:

• car guide rails;
• an elevator car;
• a hoisting rope or two or more parallel hoisting ropes;
• a traction sheave configured to be disposed in a first location that is fixed relative to an elevator shaft of the elevator;
• a compensating system configured to be disposed in a second location that is fixed relative to the elevator shaft;
• a plurality of first diverting pulleys in an upper part of the elevator shaft;
• a plurality of second diverting pulleys in a lower part of the elevator shaft;
• a plurality of third diverting pulleys on the elevator car;
• and
• a plurality of fourth diverting pulleys on the elevator car;
• wherein, when installed, the traction sheave moves the elevator car using the hoisting rope or two or more parallel hoisting ropes,
• wherein, when installed, the hoisting rope has first rope portions going upward from the third diverting pulleys to the first diverting pulleys or the two or more parallel hoisting ropes have first rope portions going upward from the third diverting pulleys to the first diverting pulleys,
• wherein, when installed, the hoisting rope has second rope portions going downward from the fourth diverting pulleys to the second diverting pulleys or the two or more parallel hoisting ropes have second rope portions going downward from the fourth diverting pulleys to the second diverting pulleys,
• wherein, when installed, the compensating system causes a first rope tension in the first rope portions,
• wherein, when installed, the compensating system causes a second rope tension in the second rope portions,
• wherein, when installed, the compensating system compensates rope elongations in the first and second rope portions so as to maintain a ratio of the first rope tension to the second rope tension substantially constant,
• wherein, when installed, at least some of the first diverting pulleys have been rigged in the lower part of the elevator shaft,
• wherein, when installed, at least some of the third diverting pulleys have been rigged in the lower part of the elevator shaft,
• wherein, when installed, the at least some of the first diverting pulleys, rigged in the lower part of the elevator shaft, have been raised in the rigged state to the upper part of the elevator shaft,
• wherein, when installed, the rigged and raised first diverting pulleys have been mounted in place,
• wherein, when installed, the first rope portions are not directly above the elevator car, and
• wherein, when installed, the plurality of first diverting pulleys are mounted directly to the car guide rails or each of the plurality of first diverting pulleys are mounted to the car guide rails via a separate supporting element.
