The rope suspension (1) is provided with at least two diverting pulleys (7, 12), around which the hoisting rope (4) is passed in such manner that, in the running direction of the hoisting rope (4), the first diverting pulley (7) is between diverting pulleys (6) and (S) connected to the counterweight (3), and that, in the running direction of the hoisting rope (4), the second diverting pulley (12) is between diverting pulleys (11) and (13) connected to the elevator car (2). In addition, diverting pulleys (7, 12) are attached to an adjusting element (17), by means of which the angle of the plane of rotation of the diverting pulley can be adjusted.</p> |
