The present invention relates to a limiting mechanism for an elevator compensation rope tensioning pulley, an elevator compensation apparatus including the limiting mechanism for an elevator compensation rope tensioning pulley, and an elevator system. The limiting mechanism for an elevator compensation rope tensioning pulley according to the present invention includes: a first limiting component, disposed on a frame of an elevator compensation rope tensioning pulley, and kept in position by a tensioning force of an elevator compensation rope together with the elevator compensation rope tensioning pulley and the frame; and a second limiting component, limited at a suitable position relative to a guiderail of the elevator compensation rope tensioning pulley, wherein a vertical distance within a predetermined range is kept between the first limiting component and the second limiting component, and, when an upward displacement of the elevator compensation rope tensioning pulley reaches the vertical distance, the first limiting component collides with the second limiting component to limit the elevator compensation rope tensioning pulley to make the elevator compensation rope tensioning pulley stop moving upward. |
